Default 74 corvette electrical problem

So, i had electrical problem for years, something was bleeding.
Couple of month ago, i decided to change radiator.
I drove around a little bit.
Unfortunately left main cutoff switch( for battery ) on one day. managed to kill the battery. Also replaced starter.
long story short, it was sitting in between repairs for a month.
Now i have a short somewhere, and it keep popping gauges 10A fuse, when i try to start it.
Where should i look for it?

You need a good wiring diagram that shows all of the items connected to that 10A fuse, plus you need to find anything that may have been connected to that circuit and then isolate them one by one.

I'd start at the starter/solenoid followed by the alternator.

Coming off that 10A fuse, on the side closest to the brake pedal is a pink wire with a black stripe that goes to a white ignition switch connector. It branches off and goes back the the box, to under the hood.

The other side of the fuse, a pink wire goes to your gauges, a large seat belt interlock relay connector clip, a smaller seat belt relay connector clip, door ajar lamp, and the parking brake alarm bulb.

A wiring diagram is a must a this point.

The FUEL, WATER TEMP, OIL PRESSURE and also the light for your parking brake are on this circuit from what I can remember

The AMP meter is NOT powered by this circuit

Thanks

I am still shocked that my mind can remember this stuff. Because sometimes I get it all backwards, sideways, inverted and twisted.

Happy to hear that. I thought it was just me.
50+ years of cars, mixed with 30+ years of 9 different big airplanes, it gets a bit tough to keep them all in their own files. (and no, I'm not 90. I kept playing car while playing airplane)!!
