HELP with electrical/fuse issue!

[WVZR-1]

The under hood lamps are fed from inside the car through C100 that is a 3" X 3" 'pass-thru' connector that is down low and behind the battery vicinity. If you washed the entire under hood area and the left rear in the battery vicinity it certainly got drenched. It would take a very long time for it to dry out if indeed it got drenched. Remove the battery and you can access it I believe and maybe dry it out with a blow dryer. You should be able to follow the under hood harness back and along the left side to the C100 connector. You could have a break in the under hood harness between the C100 and the 2 connectors to the lamps. If the C100 got drenched it's got so much sealer that's likely dried out it's taken on a good bit of water.

Is that your problem? Very hard to tell but it could be the next most likely spot to concentrate on. If you have a FSM the C100 is displayed quite well in book 2 8A201-8.

Good luck.

Thanks for the direction, Dave. Will pull the battery and give it a try.

I know they were DEFINITELY on when I started to clean but I can't remember whether they were on when I dropped the hood; just wasn't thinking about it. If I had to guess, I'd say they were off. But the weird thing is that I unhooked those lights this afternoon during my investigation (individual connections under each headlight) and I'm still blowing the fuse. Seems to me that this must eliminate those lights as a potential cause. Or am I missing something? Thanks again bro!

You need to unplug every other device that Franke said post 4, besides the UH lights, then plug multimeter probes into the fuse + and - sockets.

Does it show 12V still?

Not a real difficult task, and not intermittent. You got a connection right now, waitin' for you to see it, sort of, where there ain't supposed to be one.

UPDATE: after several beered-up conversations with different buddies of mine, where we agreed that if the problem was anything other than a) water or b) corrosion left by water, it would be ONE HELL OF A COINCIDENCE, I finally gave up and took the car to an electrical specialist. $300 worth of troubleshooting later, he traced the problem to a pinched wire in the passenger door, and all is perfect now.

So, to review: when I started spraying water under the hood everything was perfect. When I finished, I had a blown circuit. Except, the two turned out to be somehow completely unrelated. That's what I call ONE HELL OF A COINCIDENCE!!

My Corvette is undoubtedly, absolutely, unequivocally...a woman. I knew exactly what I did to piss it off but after I spent a bunch of money on it, it laughed at me and told me I'm completely wrong and an idiot.

Thankfully, I'm also single!!!
