    First of all if you are using 100 Mbps Switch you don't need those two pairs you need only 1-2 and 3-6 pairs, but for 1 Gbps you need 4 pairs, for further information I have to know what kind of Network Tester you are using, it is possible that the patch cords used for testing aren't good try with different patch cords.

How do I check the ignition coil


Ignition Coil Primary Circuit Test

Remove the coil. THEN set your ohmmeter scale to RX1 and place ohmmeter leads on the primary coil windings A (front of coil) to B (middle of coil), B to C (front of coil) and check for primary coil winding resistance which normal resistance range is zero point five and zero point seven ohms. If primary resistance is not within this range check out test results below.


Ignition Coil Secondary Circuit Test

With the ignition coil removed from the motorcycle and the ohmmeter set to the RX1K scale place the ohmmeter leads on the secondary coil windings B (middle terminal) to

R (rear secondary terminal/socket), B to F (front secondary terminal/socket) and check for secondary coil winding resistance which normal resistance range will be 5.5-7.5K ohms. If secondary resistance is not within this range check out test results below.


Test Results

A low resistance value indicates a short in the coil winding which requires coil replacement.


A high resistance value might indicate that there is some corrosion/oxidation of the coil terminals requiring the coil terminals to be cleaned and the resistance test then repeated and if after the test is repeated the resistance is still high after the terminals were cleaned the coil must be replaced.

If there is an infinite ohms or no continuity) resistance value the coil is open and must be replaced.

Bike has no spark


Check your pick-up sensor located inside the timing cover, behind the adjustor plate. If the filament is not intact you will have no spark.
A defective coil, cam position sensor, or stator will also cause a no spark condition.
Ignition Coil Primary Circuit Test
Remove the coil. THEN set your ohmmeter scale to RX1 and place ohmmeter leads on the primary coil windings A (front of coil) to B (middle of coil), B to C (front of coil) and check for primary coil winding resistance which normal resistance range is 0.5-0.7 ohms. If primary resistance is not within this range check out test results below.

3com Switch Intermittently Losing Connection.


this could be a problem with the second switch unit. what happens if you connect a pc to this cable, is that intermittent, if so, that is your problem. try fault finding with a LAN cable tester to see if there's any issue with the link cable.

I have a broadband DSL modem/router in my home office. I also have 2 CAT5e ports there. I want to feed the Internet signal from the router (one of the ports on the back) through a CAT5e point up to my...


Hi Joe,

How are you connecting to the port in the back of your router? if you have crimped a male plug on to some UTP cable then this may be the problem. UTP cable has a solid condutor and needs a different male crimp plug than UTP patch cable, which has stranded conductors.

I suggest you connect the UTP cable between the office and the loft to an RJ45 wall or surface socket in the office, use a terminating tool designed for the make and type of outlet you use, i.e. if using an ADC socket use the ADC termination tool. The sockets are designed for solid cable and have a colour code for you to follow. Then use a factory terminated patch cord between this socket and the router port.

I assume you have terminated the cable from the office onto one of the patch panel ports and want to use a patch cord to patch from this incoming socket to the sockets that are terminated onto the cables going to your other rooms. If you have access to a laptop connect this directly into the router port and ensure you have an internet connection, then plug the patch cord connecting the loft port into the router and take the laptop into the loft and ensure you have a connection at the incoming port on the patch panel. If you get the connnection there then use a factory patch cord to patch to a room you would like a connection in and then take the laptop to that outlet and ensure you have a connection.

If you want to run outlets in multiple rooms without re-patching every time then you will need to have an active switch in your loft and connect the port from the office to this and then patch out of the switch ports to the various room outlets.

Hope this helps.

Cheers, Jason

Using patch panel fields and patch cables versus running cat5e and field crimping a modular RJ45 end


I would tell you what I think of your IT folks, but I don't want you to rate this response as IA :-)

Yeah, they have a point. Wiring point-to-point does cut down the chances for failure....provided they used the proper plugs and don't plan on moving them around. It gives them job security because you have to label each cable and when the tags fall off, only they know where the cables go. Plus, a structured cabling system give you, well, STRUCTURE. You're not at the mercy of the guy who "crimped" some imported 8-pin plug on a piece of wire. Wait were those solid or stranded wire plugs? It may run 10 Base T, but it is unlikely that it will run 1000 Base T.

A proper infrastructure contains a patch panel properly labeled and jacks at the computer end, with patch cords of various lengths to the computer and switch. We're a Leviton house, so the link is to their web site.

Speaker protection fault on rx-v557


Hello, you must first tested with a voltmeter in DC entrance if you have a DC voltage on all the terminal outlet speaker, normally you must obtain 0Vdc+/-50mV on each out speaker with control volume to minimum, you can stay or remove the speakers during this test.
