How do you test an IronHead voltage regulator?
Run the engine at about 2000 RPM. MOMENTARILY [not longer than 10 seconds] connect a jumper lead from ground to F and read the meter. The meter should read 25 to 30 volts DC. If the generator fails this test it must be disassembled for repair.
How do you test a stator on a Sportster?
Un plug stator. Set multi meter to ohms. Check each pin to ground ( one lead to pin, one lead to ground) Both should be open. Check resistance from one pin @ the plug to the other, should be some, but low.
What was the name of the Sportster electric generator?
This generator is called the model 65A. It stayed on big twins until 1969 and Sportster until 1981. From 1982 to early 1984 the Sportster used the 65B. The 65B was made in Japan.
How to check the charging system on a Harley Davidson Sportster?
To check your charging system: Start the engine and record the battery voltage on your multimeter. The voltage should be near 14 volts. Raise the engine RPM’s to 2,000 and turn on all your Sportster’s electrical accessories, such as lights, radio, etc.
How are generator relays tested in the field?
Generator relays (SEL 300G, GE489, Beckwith M3425, etc.) are field tested and checked for the correct calibration with our highly advanced 3 phase test-sets. It is critical that you can, with full confidence, trust the instruments on your generator system.
How to find a short on a Harley Davidson Sportster?
Another test to locate a short is by using a compass. Run a compass along the affected circuits wiring and watch for fluctuations in the needle. When a fluctuation is noticed, you may have found the shorts location. This works best with larger parasitic draws.

How to check for parasitic draw on Harley Davidson Sportster?
You may notice this as a headlight that remains dimly lit even with the switch off. To check for a parasitic draw: Turn the ignition off. Remove the positive battery cable. Set your meter to read amps. Connect your multimeter in series (one probe on the battery positive terminal, the other on the positive wire) and record the reading.
Why did the Sportster Charger change terminals in 1969?
This was done to keep the brush insulator dry. The paper insulator used back then would swell causing the brush to stick. The A and F terminals swapped positions to keep the current in the field coil flowing in the proper direction. This generator is called the model 65A. It stayed on big twins until 1969 and Sportster until 1981.
