Hey Guys, I'm at work so I didn't have time to trouble shoot this on the car so I thought id ask all of you instead. I have recently wired a gauge in my dash that is a 4 in one gauge. oil pressure, coolant temp, volts and fuel are measured and it lights up when you turn the headlights on. I got it all done and everything worked perfect until i came out this morning and went for a little drive. the gauges all seemed to be working correctly but as it was early i turned the head lights on and they all pegged out!? I shut the head lights off and they went back to were they should be. Also, the light in the gauge did not turn on when I turned the headlights on like it did previously/ like its supposed to. My thought is that a ground wire somewhere isn't grounding, like something loosened up from when it was working previously. Does that seem feasible to you all? It's something easy to check but don't have the time right this minute so figured id through it out there. its an Omega Kustom instruments 5" 4 n 1
I'd bet on a bad ground. The temp reading on my p/u jumped about 20-30 degrees when I ran with the headlights on. Pulled into the garage, killed the lights and she was running cool again. All because of a poor ground. Pulled a strong ground to the gauges and all is good now.
Easy to check out with a simple jumper wire. Clip on either end gage cluster to known ground. If that's doesn't fixit. Ground the headlites.
You have a poor ground, most likely in the lighting circuit. Trying to find a ground through the gauges.
Easy check, run a ground wire direct to battery and hook that to your current ground and see if problem goes away, sounds like your chasing grounds.
looks like my ***umption was correct judging by your replies, I recall reading in the instructions that almost all problems that are called into there tech line are bad grounds. we'll find out tonight Thanks guys
Original headlight switches had to be grounded to the dash OR a separate ground connection, because when you turned the switch all the way to dash light dim, the dome light came on. The switch sent ground (Only in that position) to the always hot dome light circuit, BUT only from ONE particular connection on the switch. After checking your grounds, make sure that the power for gauge lights comes from the proper pole on the headlight switch and that the switch is OK. Dash light power normally comes off the switch where the rheostat controls the voltage and bulb brightness. Twisting the knob to right usually increases the voltage at that connection, but only when the switch is pulled out or on. Hope this helps.
Problem resolved, lose ground as suspected Posted using My **** Tracey watch and the full custom HAMB app
Yeah I always try to post what the problem turned out to be on trouble shooting posts so it may help someone else. To be 100% honest I tightened up all the bolts to the grounds and after I had them all tight I noticed one of the ring terminals wasn't connected to a wire! Not sure how I didn't see that one haha. Bad ground as suspected
Hey Tim! Send us a pic of your dash if you can. I've always wanted to see one of those 4in1 sets in a fattie. Thanks, Mike
Hmm I'm pretty sure there should be some photos in the last few pages of my build thread if you want to hunt that down... My desk tops of of commission a the moment let me try out this fancy new app and see if I can't put one here
Stolen from my wife's Instagram from our drive Saturday. Not the best of the gauge but you get the idea until you find them on the build thread Posted using My **** Tracey watch and the full custom HAMB app
