And its the momentary opening of the points that causes the spark. Also.... my points seem fine but there is some blackening/charring on the shaft they make contact with... can I dress it with steel wool so the electrical contact is good again? It seems as though my points are opening up at the full advance mark. Also should the igntion be turned on while checking timing (not the engine running just the battery in the circuit). When I turn off the ignition and check it the continuity buzzer on my multimeter is going off all the time... it *never* shows an open contact. yet the bike runs,The easiest way to do this is to use an Analog Ohm meter. If your meter uses a tone that's fine too. When you use your ohm meter, you want the system to be discharged and isolated ... that means you want to remove the battery !!! When you check points timing statically, you are only checking for resistance. One ohmmeter lead should be connected to a good ground (on the engine preferably) and the other lead should connected to the wire leading to the coil. When you rotate the engine, (IN THE PROPER DIRECTION! Wink ) you need to pay attention to the ohmmeter. The exact instant the needle jumps to infinite resistance, that's the place your plug fires. (the exact moment the points open, in other words) This should occur on a designated place that is engraved on the points plate .. (usually maked with an F.) The other marking here usually indicate T for tdc, and usually || for full advance. Be sure that you are not timing the bike 180 degrees out. Also, be very careful while timing - USE A PROPER SIZED SCREWDRIVER! to prevent stripping a screw head (Which are a PIA to replace.) ,,,

If I had a new timin chain put on my 1994 Chevycaprice with the 5.7 an if they move anything wrong will my car be off timin


A new timing chain will not affect ignition timing unless the chain is incorrectly installed then the whole engine is out of time. Why not state what the problem is instead of a generic question like you posted.

Any opinions on what's better electronic ignition or points .what are the pros and cons to both of any


electronic ignition will beat points hands down any time
to understand this you will need an explanation of how each works.
with a points system there are a set of points , a condenser and a coil
when the points are closed the current flows through the coil windings and produces a field flux
when the points open this field id collapsed and that produces the high voltage for the spark ( understand that current has mass and when the points open the current still flows and that is absorbed in the condenser-- that continuing current flow acts like an arc welder and burns the points )
to make this collapse happen faster the condenser back feeds current through the coil windings and so the voltage is boosted from 12 volts to around 17,000 volts
This relative low voltage induces a high current flow which over a short operating time burns the center electrode of plugs away , requiring frequent plug gap adjustments and plug replacements
problems associated with points include
point gap constantly closing from the wear block being worn away
point bounce at high rpms
coil flux saturation falling off at high rpms reducing the intensity of the spark
water and moisture in the distributor causing loss of spark
on the other hand with electronic ignition there is no points to
get wet
bounce
close up
no condenser to fail
points burn
the electronic system works on a much lower voltage ( 5-7 volts) and a pulse that initiates the action in an electronic circuit that is controlled by transistors and capacitors
This allows for a more rapid increase and decrease in the coil field flux and that increases the voltage to the vicinity of 60,000 volts
this reduces the current across the plug gap and that results in longer plug life and no change in plug gap settings ( EFI systems using quality plugs will never need changing of the plugs from electrode loss)
as electronic systems are sealed there is no problem from water as there is with points , although the same problem remains with moisture in the distributor cap
Now we have a low voltage spark with high current flow to ignite the mixture against a very high voltage with low current flow to do the job
to make it even better some electronic systems will actually continue a series of sparks so that the flame in the mixture is continually being ignited as against the one spark from a points system ( the air fuel mixture is not static but continually rotates -swirls in the combustion chamber)
what does this mean
better economy at higher rpms
better burn rate of the mixture producing power for all of the power stroke
smaller coils
with ECM units that control the ignition , it also controls the ignition timing according to rpms , and throttle setting and mixture setting reducing the need to alter the spark timing for different fuel octane ratings and altitude conditions as it is done automatically to suit the reports from all the sensors
So as I said
electronic system win hands down over points every time

Mercedes c class 2001 elegance, key fob not working everytime its pressed. I have had the batteries checked and they are still working fine, any advice as to what is causing this?


Most likely needs to be re matched to the car.

Two bits of info off the net for you

C CLASS (1993-1997), E CLASS (1995-1997), SLK (1996-)
Procedure
1. Point the remote control at the receiver - this should be located in the driver's door handle or next to the boot lock button.
2. Press the lock/unlock button.
3. Within 30 seconds manually lock or unlock the vehicle using the passenger's door lock or the boot lock.
Alternative method
Procedure
1. Point the remote control at the receiver - this should be located in the driver's door handle or next to the boot lock button.
2. Press the lock/unlock button.
3. Within 30 seconds, switch the ignition ON.

Procedure
1. Point the remote control at the receiver - this should be located in the driver's door handle or next to the boot lock button.
2. Press the lock/unlock button.
3. Within 30 seconds, turn the ignition switch to position II.


and

1. Place key in ignition lock and turn to position 2 [all ignition lights on]
2: Turn key to off position and remove from ignition.
3. Within 10 seconds:
3a: press the Close [Lock] button and hold it down
3b: while the Close button is still depressed simultaneously press the Open [Unlock] button. Press and release the Open button 5 times [still holding the Close button down]
3c: Release both the Close and the Open buttons at the same time, and immediately push any of the two Open buttons once [i.e. either the Open doors or the Open Tailgate]

This information is for the resetting of a previously synchronised key to match the security system after batteries have been removed or replaced. This information does not work with new keys which it seems must be taken to a person with a key synchronisation device [or a super-ripoff-expensive MB dealer]

hope this helps

How does the firing system work step by step from the battery to the plugs on a 1994 road king v-twin motor points /condensor


To begin with, a 1994 Evolution powered Road King did not come from the factory with a points type ignition. It came with a solid state ignition system. Harley went to a solid state ignition in their Big Twin engines in 1979. If your's has points in it, it has been converted to that system. So, I'll simply explain how an ignition system works in a general manner.

When you turn the ignition switch on, voltage is supplied to the primary windings in the coil. This voltage builds up a magnetic field. When the points, or the Hall effect sensor in the case of an electronic ignition system, breaks the circuit ground, the magnetic field collapses inducing a high voltage low current pulse in the secondary windings of the coil. This pulse goes to the spark plug via the spark plug wires where it jumps the gap between the spark plug's center electrode and the ground electrode.

Now, in a points type system, the ignition timing must be advanced by means of a mechanical advance unit where the electronic ignition uses electronic circuitry to advance the timing according the RPM of the engine.

How does my 1939 evinrude work electric wise


Typically for small outboards.. that era and for many many years after.. use a Flywheel ignition System. a Magneto, Coil, Condenser and Points..

Most of those parts are located on the Magneto stator plate under the magneto "cap". Magnets rotate past the static coil.. hence stator..

The Magneto/Magnets rotate past the coil creating an electric current.. The condenser controls the volatage spikes or modulates the voltage directing the correct voltage to the spark plug. The Points open and close allowing the voltage when closed to travel to the spark plug at the proper time as in or during Compression Stroke / Power stroke.. Which is why timing is so important..

This is a very basic description.. proper operation depends on all parts being in good condition and the timing being set correctly.. good fuel and air supply.. not to forget a proper operating spark plug gapped correctly.

There are youtube videos (of course there is) on how to check the various components of early outboards..coil. condenser.. points etc..

Very simple system..performing a complex dance.

Hope this helps.

Best of luck

What is the feeler gauage measurement on the points describe how to set points bobnichol what is the gap reading for the points and...


.45mm or 18 thou . Set them when the rubbing block of the points are on the highest part of the lobe. Reset the ignition timing after setting the points as points setting changes the timing. Use a strobe light or if you dont have one you can do it statically . Put the engine on its timing mark on the front pulley not tdc. loosen the distributor turn the ignition on and slowly rotate the dissy until you hear the small tic of the points opening and the spark jumping. at this point re tighten the dissy. That should do the trick If this helps Please Vote Jeff

I need to know how to set the distrubtor


The ignition timing is not adjusted with a timing light or with the engine running, and to set the ignition timing follow these procedures.

There is a mark or notch on the distributor housing that the rotor should be pointing to when the engine is on TDC. (Top Dead Center) This "Static" timing is all that matters and the computer will be able to control the timing as long as the ignition rotor is in that position when the engine is at TDC.

1. Place the engine at top dead center.

2. Look under the distributor cap and find where the number one terminal runs under the distributor cap, and where that position on the distributor cap corresponds with the distributor housing, and it should match up to a mark or a notch on the distributor housing (usually has a #6 for 6 cylinder engines or a #8 for 8 cylinder engines) indicating the number one TDC alignment position.

3. With the engine on top dead center the ignition rotor should be pointing to the number one TDC alignment mark or notch that is on the distributor housing, if it is not then loosen up the distributor and turn the distributor until the ignition rotor is pointing to and aligned with the TDC alignment mark or notch on the distributor housing and then tighten down the distributor, the engine should now be "Static" timed. (The more precise that you are aligning the TDC alignment mark with the ignition rotor the better the engine will run, and it will be less likely that there will be a camshaft to crankshaft correlation problem)

If the distributor can not be turned enough to align the ignition rotor with the number one TDC alignment mark on the distributor housing, or the distributor does not set properly and will not allow the installation of the spark plug wires then the distributor is not installed correctly and is most likely a tooth off and it will need to be re-installed correctly. (The distributor should set like it is shown in the firing order diagram when it is properly installed)

Here is a firing order diagram to also help assist you.

Some distributors have the hold down bracket secured onto the distributor housing and the distributor can not be turned into alignment and then tightened down into that position, and these distributors will only fit into the engine and correctly align on "Static" timing one certain way, and when it is correct the distributor hold down bracket bolt can be installed and the TDC alignment mark on the distributor housing will remain properly aligned with the ignition rotor.

Just rebuilt bottom and top end cant fiqure out how to set timing


The ignition timing is CDI ignition, pre-set at the factory. You can't change it. The valve timing is the only timing you can do and that is done by lining up the static cam timing mark and the timing mark on the flywheel.

If you simply installed the cam chain on the gear without paying attention to the position of the crank and the position of the cam then the valves are likely not opening and closing at the correct time. Too far off and the piston can hit the valves and bend them and possibly crack the valve guides.
Check a service manual. Cam chain timing procedures will be shown in the manual.
