Default Alternator / Stator? Or both

New to my Ironhead and new to anything electric

the previous owner converted to alternator/regulator

It’s got charging issues. Tested relay, battery and regulator and all are good.

in reading online it’s pointing me to stator. Since it’s alternator conversion, isn’t the stator INSIDE the alternator (like a car?) and not inside the engine? If this is the case I just need a new alternator…or are they 2 separate components on this bike

The stator and rotor are one. The alternator will be right at the front where the generator used to live,



look here

I have had luck with both. Alternators if you are having problem charging usually it is a bad ground on the regulator. You ground them on the back. I run mine to the battery ground with a coil so the vibration does not break the wire.

Harley Generators with a Harley regulators work well as well.

how did you attach the ground to the back of the regulator?

I have one on my 77 XLH. Here's the TROUBLESHOOT GUIDE.TROUBLE SHOOTING

1. Make sure all connections are made.
2. Make sure battery is in good working order.
3. Make sure regulator is grounded Well
4. To test alternator on bike you must have an AC volt meter.
A. Disconnect wires from alternator to regulator, hook up meter by placing positive lead to one of the wires and negative lead to other wire coming from the alternator.
B. Start bike and read meter at 1500 rpm’s. It should read 12 volts. At 2000 rpm’s 15 volts, and at 4000 rpm’s 26 volts.

Reading may vary depending on meter. If you don’t get any reading at all, check wire end and make sure they are making contact with the wire and not the insulation. If everything checks out okay then the alternator is working fine, and the regulator should be checked.

C. With regulator still hooked up to the battery; but not the alternator, place DC volt meter across the lead on the regulator just like you did with the alternator. Do not start bike!! If you get any volt reading from these leads there is a short in the bike some place. If no reading this is good.
D. To check regulator off of bike, take an OHM meter and put it on 1 X setting. Put the positive lead on the lead that goes to t he alternator and negative lead on the wire that goes to the battery. It should read about 4 ohms. Then test the other lead. If both read the same the regulator is not shorted.

E. Make sure the wire coming out of the regulator that goes to the battery is going straight to the positive side of the battery, NOT going through any relays or resistors
