How to test the battery and voltage regulator on a Harley?

Step 1. Check the voltage of the battery while it is disconnected from the bike using the multimeter. The volts should be no less than 12 volts.

How can I identify stator problems in Harley Davidson?

Take a test light and clip it to the negative terminal of the battery and then touch first one pin and then the other on the plug that goes to the regulator. If you get even the slightest amount of light from the test light the regulator is toast.

What should the volts be on a Harley Davidson?

The volts should not drop below 9.6 volts when the starter engages. Turn the throttle to rev the engine. As the engine is revved, the volts should go up to 13 or 14 volts.

What should the voltage be on a battery regulator?

To do this with a meter which is more accurate: black lead to battery ground, red lead to each pin on the plug, start with the voltage scale higher than 12vdc and move voltage scale down in steps for each pin. Any voltage is a bad regulator. You may get battery voltage on all three pins on the newer 3 phase regulators.

Very simply, just Right-Click on the Knocksum line, click “Edit”, then under “RequestID” change it to 3E, if not already. The correct address for 1997+ ECU’s is 26.

When did the Harley Davidson Evolution engine come out?

The Evolution (Evo) engine is a V-twin engine that has been manufactured by Harley-Davidson since 1984 for a variety of different motorcycle models. The engine design is often credited with saving Harley-Davidson from bankruptcy after the management buyout and subsequent reorganization that the company went through during the early 1980s.

How can I check the voltage of my bike battery?

Check the voltage of the battery while it is disconnected from the bike using the multimeter. The volts should be no less than 12 volts. Connect the battery to the bike. Reconnect the multimeter to the battery.

Why was the EVO engine important to Harley Davidson?

Many old timers give AMF a bad rap, but the $$$’s they plowed into the EVO development paid big dividends later, saving the H-D company from “extinction” and eventually it’s success enabled the H-D family to “buy back” the company and field a whole generation of engine designs that exist today…
