i have power going to the ignition switch while the key is in the off position, but as soon as the key is in any other position i loose the power.

i really need to know what the hell is going on here.

thanks

Is your car a manual?

Do you have a factory alarm?

3engineRex

loose connection at the underhood fuse box

i just checked that, and all is good.
i have no grasp on this problem what-so-ever.
i mean it just doest make sense.

its just a circut with a switch. and all that switch does is change the path of the current. i have power in this circut before the switch. when i flip the switch, the power disappears.

battery to the 80A(i always have power on each side of this fuse) main fuse to the ignition switch to the starter to the battery.

the starter(its good ive tested it, autozone and checker have also tested it) is grounded to the engine block, could something else be shorted and grounded to the block causing this circut to short out, say the alternator?

i have three switches, all three end the same way

Nah, not if it looses voltage before the switch.

Anyway, are you sure you checked the wires were they attach to the 80 amp main fuse.. I have seen those get loose and do exactly what you describe

3engineRex

I pulled them off cleaned them put them back on. and I always get power after the fuse.

I did realize about 5 minutes ago that the ecu is also part of this circut, how do i test for a bad ecu( the ecu is actually in my lap right now)!

Icemark

ECU won't shut off power, it just gets the crank signal

Icemark

how about your ground from the battery too the body???

and you have checked that you don't just have a dead battery by turning on the lights, right???

When you turn the switch to ON, do you lose power before and after the 80A fuse?

Or do you constantly have power before/after the 80A fuse, but no power after the switch? Maybe a broken wire?
