Need help w/ electrical problem

['92eclipsegst]

Here's a little background on the car: it's a '95 eclipse gst w/ a sfp tubular manifold, garrett 50 trim, greddy emanage blue, ect. I bought the car from the previous owner after the timing belt went and bent all the exhaust valves. I recently had the head rebuilt and now have it all back together but I have an electrical problem that I can't fix. The problems are: there's no power to the coil, the fuel pump, or the power windows, and the only light on the dash that lights up is he door ajar one. I've checked all the fuses and fusable links and they're fine. Any idea what could be causing this? Is there a fuse or relay that provides power to all these things? Could the fuel pump and coil be an issue with the emanage? Thanks in advance.

It's possible that these circuits have been shorted out from melted wiring. If that is the case though, the battery would die after sitting for awhile. If you have a voltmeter, start checking the wires from the fusebox till they get to their destination.

Well every time I go out to work on the car the battery is dead so I guess I'll give that a shot.

If your battery is dead every time it is VERY likely that there are shorts in the wiring. A similar situation happened to me not too long ago where 5 fuses in the engine bay would continuously blow. Found out that there were shorts on all five circuits.

To determine which circuits have a drain on them, disconnect your negative battery cable then connect your voltmeter's positive lead to the negative battery terminal and the negative/ground to your chassis ground. If the key is in ignition, the voltmeter should read 12v, with it turned off it should read zero. If you have a drain in the system, the meter will show a positive reading regardless of whether your keys are in the ignition. To then determine a more local place to search for the drain, start pulling fuses in the engine bay fuse box until the meter reads zero again.
