Charge the battery first. Check battery voltage with a multimeter. Start the bike and check battery voltage again. It sould be close to the same, or a little higher. Rev the bike to about 2000 rpm, while checking battery voltage. Reading should be between 13.8-14.2vdc or thereabout. If not you will need to check both the regulator and stator. Is this the original battery in the bike? If so, replace it!

SOURCE: 04 fxsti 88b motor check oil while bike is on

You need to check oil while bike is upright on a level surface. I believe from 05' and earlier the MOCO designed their softail dip sticks to read the level while the bike is on the jiffy stand.

If oil is hot,it should be at the full mark. If checking cold, it is about 1/4 inch below the full mark.

SOURCE: what's involved in replacing electric

To remove the starter, disconnect the battery. Then drain the oil from the primary and remove the outer cover. Take the bolt out of the center of the starter jackshaft. When you pull the jackshaft out, the coupler may come with it. Make sure you mark the postion of the coupler as in must go back in the proper direction.

Then from the other side, remove the exhaust system and anything else that may be in your way of getting to the starter motor. You will probably have to remove the seat and take the bolts out of the oil tank on your softail. This is usually required so that you can lift the tank just enough to get the starter out. On some, I've seen the oil tank have to drained and removed to get the starter out. Once you get access to the starter, take the two large 5/16th bolts out and the starter comes out.

Good Luck

SOURCE: My choke cable wont stay out when i first start

There is an adjustment on the cable. If you pull the knob out, you'll see a another knurled knob just behind it. If you turn the knob clockwise, it should put more tension on the enricher cable. Never put any kind of oil or other lubricant on the enricher cable. Be careful when tightening the tension knob as the parts are made of plastic and break easily. If it breaks, you must pull the carburetor in order to replace it.

Good Luck

SOURCE: bought a new battery rode

To check the output of the charging system, first, you must start with a fully charged battery. Then connect your DVOM (Digital Volt Ohm Meter) across the battery. Red meter lead to the positive post and the black meter lead to the negative post of the battery. Put the meter's function selection switch in DC VOLTS, 25 VOLTS OR GREATER scale. Start the engine and bring it to a high idle. Your meter should read between 14.5 to 15.0 volts.

If not, find where the regulator plugs into the alternator. A Big Twin is in the front of the engine and the Sportster is behind rear cylinder. In the stator side of the plug, there are two metal contacts. This is where you're going to check the voltage output of your stator. Put the meter's function switch in AC VOLTS, 50 VOLT OR GREATER scale. Start the engine and insert either meter lead into one metal contact and the other lead into the other contact. Do not allow the leads to touch each other or the engine case. Bring the engine to a high idle. If you're working on a Big Twin, you should be reading at least 30 volts, a Sportster should read about 25 volts. If you don't read this much, your stator is bad, If you do read this much, it's probably the regulator. But, since you said that you've changed the regulator at least once, I'd guess maybe another problem. Make sure you regulator is grounded to the frame. I always put one of those star type lock washers between the regulator and the frame on both mounting bolts. The regulator must be grounded.

Good Luck

While riding at night my bike died and could not be started without battery jump. Where do ifind the magneto and regulator to test? and wht output should i be expecting?

its an alternator not magneto, there should be 3 wires white or yellow, going to the reg\rectifier, multi meter across any pair(unplugged) should show 50-80 volts at 2000rpm non of these should short to earth, multi meter across battery should show up to 14v at 2-3000rpm.with everything plugged back in
if alternator checks out, and no voltage more than 12 at battery , replace regulator,,

all assuming the battery wasn't fried when it ran out of acid

my guess is new stator\alternator required

Harley ignition problem

The alternator is bad. IT is not charging the battery. When the voltage drops on the battery it dies, When you jump it the bike starts because power is coming from some other source but when you disconnect that source it dies because the battery has not charged back up.

2. Loose, corroded or broken battery cable.
3. Alternator not charging or below normal rates.
4. Failed ignition coil, ignition/electronic module.
5. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor.
6. Faulty ignition switch.
7. Water or dirt in fuel system, carburetor or filter.
8. Fuel tank vent system plugged or gas cap not venting.
9. Fuel tank empty.

All the lights on my 2004 s10 blazer are strobing or blinking

Its most likely the voltage regulator which is most often attached or inside the alternator its a replacable item. Normaly the sighns of an alternator gone are a dying battery.

The Battery and or Stator is bad. Just like on a car if you pull the negative cable off the battery while the car is running and it dies your alternator is bad.
