Ok so I just finished my rebuild and I have a stock 351 pcm (winsor) . My problem is ...

I wired my new gauges up and two are giving me problems .. voltmeter/ oil pressure

Main harness from motor has 8 pin
Power
Ground
alt
Coil
tach
Oil press
Choke
Temp

But on this diagram it shows the output for alt to have and orange wire that runs from alt
To Batt positive on seliniod and then to the signal for the gauge ...

So when the wires are terminated as the diagram shows the meter is pegged out with out the keg on. And stays pegged out when I switch to run and or start .... ???? Does that make sense?

Oil press - PO said he installed a new sender but do I just read ohms of sender to ground to check?


EDIT: is my email

Any help would deff help me out. I'm on supra boat forums under (lively) if u would like to see what I mean ...
