Anyone know a good cliff? Electric Problem

[un_known]

Anyone have a clue why the tail lamp fuse would be blown, constantly? I replaced the damn 15A Six times, including after i replaced the damn TCU or w/e the hell you call it. I think their may be major ground problems. But any suggestions would be greatly appreciated!

What was the most recent thing you did to the car electrically? I've had WEIRD experiences with the 240 electrical system, for instance: I unplugged the front left horn, and every single time I put the key in the ignition it blew the interior light fuse. That one took me forever to figure out.

have you tinkered with anything else coming off the tail lamp fuse? like the shift lock control unit (if you have an auto that is) is on the same circuit. The only thing I can think of to do is to reseat the TCU and see if that cures the problem. I don't know if it would since the TCU isn't on the tail lamp fuse block

I forgot to mention that around the same time as the problem began to occur, I installed an aftermarket CD player. Reseat TCU?...Elaborate

double check your radio wiring. there may be a cross somewhere on there. But that would more likely blow out the interior lights and door chimes

I'll bet dollars to peso's it is being caused by something you did when installing the CD player. What circuit did you tap into for the switched power source? (The one that comes on with the key moving to the on position).

[thekage]

Yeah.. check switched voltage.. and also where you tapped the "illumination"

Its not the Cd Player, im not saying that it wasnt the Cd player that started the problem in the first place, but I completely disconnected the Cd player and still no illumination, no marker lights, and no tail lights. Just for kicks today I put in a new fuse and it worked for about 4 minutes. Everything worked except for the illumination, and left side markers. I bought the FSM which in this situation is basically useless, because it has nothing but a breif section in the back. Are their any other useful books for electrical? Thanks

wrap the 2 fuse plugs with wire

now that we are on teh fuse subject. I look at my fuse box for my dome light and its not burnt,poped out or upsidedown. Why isn't it comming on? I have a new bulb in there :-/
