Unhappy HELP wiring gremlin on 85'

Suddenly this morning I started blowing fuse a fuse on my block #ed 6. It kills the dash gauges and throws the charge idiot light. The only other thing that i can find not working is the turn signals. Happens as soon as the key is turned on.

85' toyota pickup standard cab 22r motor

sounds like a short or a bad ground. You could pull all the fuses and start to put them in one by one till one blows and search from there?

its obviously a short, a bad ground would just cause whatever functions to not work, it wouldnt blow fuses...and he already knows what fuse is blowing...

you need to find a schematic, or you can start tracing through the entire wire harness looking for damage, but it isnt necassarily a problem with a wire (most of the time it isnt) it could very likely be something like an internal short in the alt or some other load on that circuit...I would try unplugging everything that is on that circuit, then stick another fuse in (same size, DO NOT put a bigger fuse in at any time) and see if it blows...if it blows with everything unplugged, the problem is in the wire harness...if the fuse does not blow with everything unplugged, then it is in one of the loads...start plugging them back in one at a time to see which one causes the short circuit...

I had the same problem on my 4runner.
Turned out to be a leaky window, water was running down in the interior fuse panel and into the circuit opening relays on the pass side.

I cleaned and sanded all the ground lugs and their bolts, applied some di-electric jell and it didn't happen again untill it rained.

I replaces the window and "fixed" the leak....until it rusts worse..
Did it all again, and i haven't had a problem with it in over a yr...

then you may have a situation where a harness has chafed and is shorting out when it hits a bump...check the harness for rough spots, anywhere that is rubbing, etc..look at anything that you may have moved since the problem first started..
