Question about Harley Davidson FXD Dyna Super Glide Motorcycles
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.
