Hi,, I own a 2002 Dodge Ram Conversion van, 1500. My wife was stopped at a red light and all of a sudden the wipers turned on, the radio got loud and full of static and the headlights went out. I checked and both headlights were burned out, the wiper fuse was blown. When I replace the wiper fuse and you start the van, the wipers stay on and can't be shut off. I have not replaced the headlamps for fear of them just blowing again. The voltmeter shows just over 14 volts and the van runs fine. I was told it was possibly a power surge due to a bad regulator.
Any ideas?
Thanks so much.

Have the alternator and the regulator tested. Sounds like a power surge to me also here is a guide so you can test them for yourself. When the engine is idling high about 2k RPM the voltage should not be over 14.5 volts

Suggested Repair

Test the alternator and voltage regulator. At about 2000 RPM, charging voltage should not exceed 14.5 volts. If either is faulty, replace the alternator.

A 2002 Dodge Ram 1500 conversion van suddenly had loud static on the radio, both headlights burned out, and the wipers came on and would not shut off after the blown wiper fuse was replaced. Charging voltage was just over 14 volts and the van otherwise ran fine. The expert advised testing the alternator and regulator for a power surge, noting voltage should stay at or below 14.5 volts at about 2000 RPM, and replacing the alternator if it fails.
