Wondering how to check if my voltage regulator is working. I had a headlight delete so I hooked up a Leadog aftermarket headlight. Then I put my headlights back in and left all the wiring for the leadog still intact. When i started it up the OEM headlights came on for a second then quit and there is no power going to my gauge. I took the sled out and it would only rev to 4000-5000 rpm (I had no gauge so this is only a guess) and wouldn't go any higher. Pretty sure it sent a power surge through the system and took out my regulator (hopefully nothing else). Just wondering how I could check this myself instead of paying my dealer to do it. Thanks.
