oil pressure guge pegged and battery draining

[JoeMo]

Ok here goes I just put in a completely rebuilt 4G63 Turbo motor into my 97 Eclipse GST Spyder, balance shafts were removed.
It started on the first turn of the key but the oil pressure gauge is screwy. With the motor off the gauge is permanently pegged, with the sender wires disconnected from the sender switch and the idiot light sender the gauge is pegged. When the car is running the oil pressure gauge drops, and when the key is turned off the gauge is pegged. The battery is dead within 12 hours or so. I am assuming the pegged gauge is killing the battery, the question is what is keeping the gauge pegged. any help would be appreciated

It's time to bust out a volt meter and double check your connections. I'm afraid outside of the search term "6 bolt swap battery drain" there isn't much we are able to help diagnose without checking your wiring

Thanks here is some more to add I disconnected the alternator gauge still pegged i removed every fuse from the interior fuse box (including the 1 that is for the gauges) oil pressure gauge is still pegged removed every fuse in the engine compartment except the fusable link pressure gauge is still pegged the mystery continues

Sounds like you might have to pull the cluster off and see if there is anything going on with the wiring behind it.

[i fixed the problem there is a bracket bolted to the back of the alternator that supports part of the wire harness, same wire harness with the oil pressure sending unit and OH crap oil pressure unit Turns out the metal bracket nick 2 of the wires in the harness 1 was the oil pressure gauge feed and the other was the temperature gauge feed when i wiggled the harness the gauge fell to normal and back and forth wit the movement of the bundle I taped the 2 individual wires, re-taped the bundle, put the plastic sleeve back on and reattached the metal hanger all is well now its on to a new problem
