Default dash is still dark

Hello

I own a 1989 Corvette 6 spd manual. While it was sitting in the previous owners back yard. Squirrels ate some oI replaced the fuse and lost my dash board lights. My mechanic said that he re-replaced the 5 amp cluster fuse and now half the dash lights up. but, when he starts the car the now illuminated tach does not indicate rpm of the running car. The oil/water/milage and speedo lights are also out.
I removed the instrument cluster and probed pins c16 and d16 they did not have power. pin c12 did.
Any ideas.
The dash did work fine. Oh I put a probe connected to ground on the battery on the metal tab of the fuse. the probe did not light up. I took out the fuse and put the probed in the fuse holder and the probe did light up.
Thank you all.

Bryan has a wealth of info there, between that and the FSM you should be able to get it back on the road. One thing, take a light and see if you have gauges but they just aren't being lit up. Had that on mine, had Bryan give it a once over and it was the ground between the boards had gone bad.

This is a great suggestion. The tachometer lights up but does not indicate engine speed when the car is running. And remember the pins supplying the cluster did not have power.

Should we take out the fuse box and clean the connection? But, drives me nuts is it all worked well until I changed the fuse. Now it all went to hell. I keep thinking of the black and white wire that has no home. but there is no ground in the fuse box it is all hot.

Thank you for the help. I am considering sending it to Bryan but first I need to prove that I am getting power at the pins that supply power to the cluster.

You are not going to take out the fuse box to clean the terminals. The fuse box has about 1500 wires going into the back of it. You can clean the terminals from the front. If they ate one of the wirs going to the back of the box, that's a different matter.
