Default CTSY/CLK Fuse keeps blowing

Hello all:

I have just incountered a new problem in which I require your help with.

The CTSY/CLK (15 Amp Fuse) keeps blowing on an 85 Corvette.

I have replaced it 4 times and it keeps blowing.

I can't seem to locate the cause?

Has anyone else had the same problem?

Can anyone suggest a fix?

Thanks,

Leon

Default Been there, done that...

On mine, it was the pink/white wire that ran over to the driver's side door. Finally found the culprit by tearing out the dash, and tracing the wire....turned out to be a spot where the wire insulation was rubbed off, causing a short.....it turned out to be right behind the info center, just above the radio, but you couldn't see the wires until you took the entire dash out....Good Luck!!!!

Make sure there is no loose change falling into the cigarette lighter shaft

Check the hot wire going to the cigarette lighter that it isn't pinched or insulation abraded and touching ground.

I had a case where the screw that retains the door light had come loose and was grounding out against the bulb.

This is the circuit that most people tap into for aftermarket stereos and alarms. That'd be my first place to check.

Replacing the fuse will not fix it. And don't under any circumstances put a bigger fuse in.

Does it blow instantly? If it doesn't it'll be easier to diagnose.. unhook the battery ground and put a ampmeter between the cable and the battery post. Then start unplugging **** in the car until the amps drop down.

When I attempt to replace the 15 amp fuse, it sparks out and blows.

If I disconnect the negative battery cable, insert the new fuse and re-connect the negative battery cable it is ok for a little while.

One time I closed the hood and the fuse blew.

Another time i drove down the street and the fuse blew.

Do you have an aftermarket stereo or alarm? If so, disconnect them.

Electrical shorts take lots of patience and diligence.

This fuse kept blowing with my aftermarket stereo so I put the original back in. No more blown fuses.

This may help trace the problem. It's from my 86 but should be similar to the 85. http://members.shaw.ca/agent86/Clk-Ctsy%20Fuse.pdf

Hood lights are also behind this fuse. So, maybe one of the hood light cables are broken, and closing hood makes short circuit. Check two wires coming from both of the lights to front of car, there are connectors near headlights.

I bet you will find that someone tied in a hot wire to that fuse panel (look for a strand of wire stripped on the end that is shoved into the fuse box front or back), or that some one tapped the cigarette lighter hot lead for power to the stereo and it is shorting out (is it an aftermarket stereo? If so, pull it out and check the power inputs for bad connections, and wiring for fraying).
