SOURCE: T100 tail lights & dash light keep blowing fuses

If this vehicle has a trailer harness, that could be the problem; it could be shorted out. Additionally, if there is no trailer harness, look under the truck bed at the rear, look for a grey wiring connector that wires come out of, and run to the taillamps. I have observed corrrosion in this connector, which will result in a short circuit. You may find it necessary to cut the connector out and resplice the wires back together (eliminate the connector), if severe corrosion is indeed present.

you have to loosen the mounting bolts on the fuse panel and on the bottom side the fuse is held in by 2 8 millimeter bolts.

What would cause a fuse to blow out as soon as the battery is plugged in?

If problem on wiring circuit somewhere, replacing the parts won't fix it. If fuse 17--10 amp that fuse circuit is hot all the time. You have a short. Disconnect the wiring connector from generator, does the circuit still go to ground. Instead of blowing your fuses, use a test light across the fuse terminals, if the lite comes on, the circuit is still going to ground. Some don't like to use test lite for that test, but, anyway.
Could be problem with fuse box or the wire circuit from fuse to generator. Make sure generator wire connector doesn't show any signs of heating/melting or anything.
If you think the problem is the white wire with black tracer, you might leave a pigtail wire at both ends, hopefully the pigtails are good, then splice in a new wire for testing. If that fixes it, then make the new splices permanent and route the new wire properly.

New fuel pump, ccrm and fuel filter and still blowing 20 amp fuel pump fuse

If the components are all good, then check wiring connectors and wiring circuits, it appears the problem is after the ccrm. wiring from ccrm to fuel pump. For testing you should be able to use jumper wire with inline 20 amp fuse, from voltage to fuel pump connector, to see if it will run w/o blowing the fuse. As you can see from ccrm to inertia switch there are two connectors. From inertia switch to fuel pump, one connector. There are many ways to test. With connectors unplugged, you could use a test lite connected to battery voltage, touch correct wire terminal, if lite comes on, that circuit is going to ground, somewhere.
See that one wire that goes down, wire circuit from ccrm to inertia switch, that wire goes to pcm, I believe it to a monitor circuit, the pcm monitors the voltage on that circuit.

120 amp fuse

It sounds as if your battery may have come to the end of it's life and needs replacing. You need to get someone, preferably a garage to check your battery. If the 120 amp fuse is blowing then their could be other electrical faults on the vehicle. Do not replace the fuse without getting the battery and electrics checked out first.

I have a 1994 Ford Thunderbird LX V8. A few months ago when I put the car in park, the air conditioner and the battery amp guage quit working. I found a fuse that was bad and I replaced it and then the...

I'm betting it has something to do with the shift lock actuator or the harness to the actuator. I'm pretty sure it is located on the top of the steering column on your vehicle. The lower part of the dash will need to be removed and then the steering column lowered in order to gain access to it.

This vehicle does have an airbag and unless you experience with airbag systems I would not recommend tackling this yourself.

unplug the interlock. Replace the fuse. Start the vehicle. with your foot on the brake manually release the interlock with you hand and shift through the gears. If the fuse does not blow your on the right track. If the fuse does blow let me know and I'll get you some more info.

Let me know if you have any questions and thank you for using Fixya.com

Many cars have the cooling fan on a thermostat or time delay, to allow it to run for a short period of time after the engine turns off, to cool the engine off. You may have just never noticed it before. So I wouldn't worry about that.
Your real problem is the blowing fuses, apparently you have a short somewhere in your wiring. Putting in bigger and bigger fuses is a great way to set fire to your wiring harness. It's possible that the wire is pinched or chafed somewhere, and perhaps when you hit a bump just right, it touches and shorts.
You may have to take this to the Chevy dealer or a GOOD independent shop to have them chase it down. Unless someone out there knows exactly what this is, it could be a tough one to find.

This fuse is attached to the fuse box by screws which may be under the fuse box. 100 amp automobile fuses are always fastened in by screws and do not just push in/pull out like lower amp fuses.
Hope this helps.
