1978 corvette Courtesy light fuse problem
As you can tell from my signiture, I'm NOT a Corvette guy, so please bear with me.
I'm working on a '78 Vette, and while doing some electrical work under the dash I kept blowing the "Courtesy Lights" fuse. So, I resorted to putting a 20Amp Circuit Breaker in the "Courtesy Lights" fuse position (2nd one down on the Left Side) The circuit breaker immediately gets very hot. (I don't think I have a short, as I knew each time I blew the fuse, I was aware of the cause. and other than that, the fuse was carrying the load) Does anyone on here have a listing of what all this fuse serves? Or can you send me to a link that would show that circuit? Do circuit breakers normally get this hot? The breaker in use is about 1/4" square, black plastic with round copper lugs that fit into the fuse position. (I think it is made by Dorman) This car is being raffled off for charity in 3 weeks (July 21,'12) so money is non-existant for buying anything, and time is pretty much in the same catagory.  Thanks!

Re: 1978 corvette Courtesy light fuse problem
The problem is solved! I went 'back to the basics', and put a regular 20A fuse in the offending slot. No more problems, and all the lights work! Apparently I just got a defective breaker, as I had the doors open for about 5 hours yesterday, with all the lights on the whole time. Thanks for the input, Maxwedge

Re: 1978 corvette Courtesy light fuse problem
Light switch 15 amp fuse circuit brake and check the tail. If you have 55 corvette you have 6 volt electric fuse system, so go for 20 amp which is regular.

Re: 1978 corvette Courtesy light fuse problem
What year did the 'vette go to a 12v system?

Re: 1978 corvette Courtesy light fuse problem
JoeW & Jeff collision, All GM (and I think Ford & Mopar) went to 12 Volt systems in 1955. The '53-'54 vettes (and the other brands older vehicle models) were 6 Volt systems. I've solved the problem, and, as listed in the first entry, the car has been given away.
NOTE TO MODERATOR: Please close this thread, as we are getting away from the origional question. Thanks Stale Trooper
