Would you be able to tell me how to check if the rectifier is working? It does not look like my battery is charging. The sled runs fine, no loss of power. Lights worked after I put in the new voltage regulator. However, after I hit something in the ice today, my lights got dim again.Hangman said:I would start looking into how to test the lighting coils. Personally, I don't know that one.
If your regulator was bad, your voltage would be rather high. Maybe unplug the regulator and do a quick voltage test, but be prepared for a burned out headlight if you're not quick enough.
If you have a battery, then you will have a voltage regulator and a rectifier. The rectifier is for charging the battery. Uses different coils than the lighting circuit.
