Allright ive done the headlamp test and when I turn the left blinker on the flash module just hums. Right blinker is fine, but when I turn on the left it hangs and just hums. Does this mean the flasher module is bad? | ||

"Allright ive done the headlamp test and when I turn the left blinker on the flash module just hums." The headlamp bulb is to protect the wiring harness from melting while testing for shorts. (The bulb limits the current, an automotive fuse blows at a very high initial current - a 20 amp blade style fuse blows at 20 amps after 1 second, at 0.1 seconds it can pass almost 100 amps - BussAuto.pdf). The flasher has a DOT standard that it has to indicate a open or shorted bulb by flashing at least half or double the flash rate to indicate the fault. With the flasher humming (with the bulb replacing the fuse, there is no harm being done), remove bulbs, move wiring, disconnect the left wire off the hand control, etc... until the humming changes. Good Luck! | ||

I have to give it up to 99X1, his troubleshooting method was dead on. After plugging the lamp bulb into the fuse slot that kept blowing I just started to wiggle and jiggle till it happened. A wire was loose underneath the main fuse box.  I hate electrical problems! Took off the fuse box secured the wires and it works like brand new. Thanks for everyone who posted in this thread and the other one. Special thanks to 99X1 |
