NE IL | Spent a few hours today trying to figure out why the flashers or turn signals on the semi suddenly don't light. Put in a new flasher and fuse. When you flip the signal handle the flasher clicks a few times, like it normally does, and then gradually dies out. The lamps never flash though. When I test the prongs on the flasher while it's partially plugged in I get the test lamp to blink like it should. The turn signal lamps light up when I turn on the CL LPS lights and all other lights and functions on the truck work fine. Is there anything else I should try? I'm going to try and find some grounds to clean up in the morning. | |
