Hey guys, thanks in advance for your time. I hit a bump today and my fusebox fell down on my feet, (bad system). When I tried to push it back up into position a wire terminal arced against a screw and the truck died. It won't turn over, and the blinkers, radio, turn signals, and guages won't work. The lights and a couple of other things still work but that's it. I don't know where to begin. The only thing that I have found is that a small cylindrical three-pronged relay type thing located under the dash to the left of the fuse box stays burning hot to the touch constantly, whether the key is on or off. I tested the wires going to this relay and found that the pink wire is live at all times, whether the key is on or off. I don't even know what this relay looking thing is. Please hlep, I know nothing about the wiring system.

 

Sorry but I really dont even know where to tell you to start. The only problem I can see is that the fuse block is supposed to stop any wire frying when an arc occurs, but in your case you stated you arced the box itself. Which means you might have done more damage than you think. It only takes a fraction of a second to fry something electrical. Giving you say you dont know anything about wiring I would possibly suggest going to a professional?

 

check main fuse box under hood

 

No fuse box under the hood on a 1st gen, but check the fusible links under the hood. They are part of the wiring harness near the battery, they look like wires spliced in. They will usually look fried if they have blown.

 

My 93 had some problems as well and that cylindrical thing I was thinkin was the key in ignition buzzer, it was hot also. Check all the fuses real close,you should pull them to see, then if thats ok you need to look under the hood at the fuseable links. I took a 12v tester, the kind with the light bulb and a real sharp tip and poked both side of the links to see if they were still good. Its kinda of a pain sorting thru them. get some liquid black tape and seal the pin holes back up after pokin the wires. If any of the fuse links are fried you should be able to get news ones at the local A/P store. I think they go by color, 5amp 10amp, etc. Its gotta be in one of the fuses or links. also I cant remember but I think some of the little square boxes( circut breakers) are in the fuse block also, you can check these with a mulitmeter or run 12v thru them and see if they light up the tester. let us know what you find.

 

sorry about that,, thought they all had a main fuse box uder the hood.......but make sure you use a test light to check the fuseable links and the fuses cause thay can 'look" good and be blown.

 

Thanks for all the help guys I really appriciate it. The problem was a fuseable link. I was pretty worried there for a while considering how little I know about wiring.

 

Glad to hear it was nothing BIG. I once touched a hot wire by an alternator and with in milli seconds I had melted a few leads and fuseable links to. If you going to mess with any electronics it pays to disconnect the battery first.

 

To test a fusible link, just give it a little tug with your finger. If the metal strand is broken, the insulation will stretch.
P.S. the little cylinder under the dash that gets hot is the timer for the halo light on the ignition switch.

 

So where is the buzzer relay, it drives me crazy
