74 Road runner 318 auto Rally gauges.
So about a month ago I sent my gauges in to bobs speedometer and he fixed and calibrated my who gauge cluster because my fuel temp oil and batt gauges werent working. I got it back and installed to and now my fuel gauge works and I havent hooked any wires up to the batt gauge. I was expecting this because the previous owner put in a set of aftermarket gauges (temp, oil, batt) and i assumed the others werent hook up properly. Tonight I bought a new electronic oil sender unit and installed it instead of the aftermarket mechanical one. I looped wire around it and then put it in the correct location on the bulkhead. I then check for continuity from the sender unit to the stud on the back of the oil gauge and found out it was continuous. The ground wire on the cluster is hooked up and should indeed be grounding. I start the car up let it run for a couple mins and rev it and the oil pressure reads nothing.
I then did the same thing with the temp sender but i just used the one that was already on the car instead of buying a new one. I did the same thing with the same results as above.
What i thought was weird was that when i checked continuity from the oil sender to the bulkhead under the dash, it would read continuous whether i touched the oil or the temp prong (right next to eachother) on the bulkhead. It only worked for those two, none of the others.
Anyone have any ideas?
Also how do I hook my batt gauge up?
Thanks
