Testing ect, and oil presure gauges

[rojo1]

OK Since I've rewired the whole bronco, Centex body harness, and the rjm efi swap harness, I can't get my oil and ect gauges to work (don't move on start up or running) Today I spent half the day rechecking wiring (every thing is perfect) Testing grounds and then found out my dvr was bad. NO problem have an extra change it out. It's pulsing about 5.4 volts But the gauges still won't move ( Oh and fuel gauge works fine) Does any one know if there's a way to test the gauges to see if they are the problem?

No clue what a "ect" is but.., when key is turned to the "on" position the oil pres. needle should twitch., as in move up just a hair.... (not easy to see) if energized.

"Does anyone know if there's a way to test the gauges to see if they are the problem?"

Yes there is.... Question comes to mind....did they work B4 the re-wire... are they all the stock gauges.?

Your sig. page filled out would be a big help.

It's a very simple circuit and should be easy to troubleshoot, diagram attached. If it worked before the wiring change then it can only be the connection from the gauge to the sender unit, the sender unit, ground. If it didn't add the gauge to the list. The sender depends on good contact between the threads on it and the threads on the intake manifold, so NO TEFLON TAPE.

Ok so up date on everything. I just said ***** it and replaced my oil presure gauge, (working fine now), and my ect (engine coolant temp to answer bobs question) now working fine as well. What was up with the orignals I have no idea, but I figured if I have spares replace them and figure it out down the road. But other then that Thanks for all the thought's and help.
