Mykeys Toy Posted February 9, 2010 Share Posted February 9, 2010 That pretty much sums it up. The gauge works check by grounding it went to the top. The switch that was in there worked before pulling the motor for headgaskets and no worky after.. I bought a new one thinking I probably bounced it against something to kill it but I have nothing reading on the new one either. And before anyone asks yes it is for a gauge not an idiot light.

Turbone Posted February 9, 2010 Share Posted February 9, 2010 I just thought of something....we need to check all the grounds, make sure we got them all connected. Quote Link to comment Share on other sites More sharing options...

Mike YIKES,you should never ground that wire w/o a resistor in series to limit the current. You wont always get away with it Quote Link to comment Share on other sites More sharing options...
Mykeys Toy Posted February 14, 2010 Author Share Posted February 14, 2010 OK so the wire in my hand is yellow even though it doesnt look like it. I obviously screwed it up so where does it go?.. OPS is plugged in and no worky. BTW this is from an 86 hatch. The following pics are of more wires in general viscinity and thought maybe one of them may belong to my problem.

OPS is plugged in and no worky. BTW this is from an 86 hatch. The following pics are of more wires in general viscinity and thought maybe one of them may belong to my problemMike The wire goes to #5 lead of the 12 pole connector on the back of the gauges.You want 12V here and on #8(black/white).Grounding the yellow/black lead w/140 ohms in series should give 57 psi on the gauge. Since the gauge still moves,it is probably powered up,but look for voltage at the sender end of the wire anyway. Sounds like the sender is bad.Could you have gotten a pressure switch instead of a sender? Check the senders resistance.

Mykeys Toy Posted February 14, 2010 Author Share Posted February 14, 2010 Thats a possibility, but the switch that was in there worked until I put the engine back in. I did make sure that when I ordered it that it was for a guage not the light but that doesn't mean I didnt get the wrong part anyway.

naru Posted February 14, 2010 Share Posted February 14, 2010 Could just be a poorly connected engine harness connector too. Quote Link to comment Share on other sites More sharing options...
