temp & gas gauge working on & off

Post by omarosses »



Hello! I have a 1997 GL1500SE , temp and gas gauge working on and off, relay #3 has been replaced, it worked good for a little bit and now its doing it again. I've heard about a possible 7volt regulator going bad, if so, where is located at? any inputs are appreciated . Thanks

There is no 7v regulator on the 1500's only the 4 cylinder wings have them.

Since you already replaced relay 3, about the only other thing in common to the two gauges would be an intermittent ground to the instruments.

Update -
I said a ground, but I retract that, I think the ground going to that gauge cluster is only for the lights in that cluster. Gauge grounds are separate, and pass thru the temp sensor/fuel sensor on the way to ground, so it must be a flaky power connection to the gauges. I doubt relay 3 is the issue because there's an awful lot of systems going thru that relay, if the relay were bad there'd be a lot more than just gauges not working.

Intermittent problems are the worst kind, you get in there with a test light on a connection and suddenly things are working again and of course you can't find a fault if there is none. I'd start troubleshooting by pulling plastic, the radio shelter and left side, and start wiggling wires to see if you can find a questionable connector somewhere in the wiring harness going between the relay and the gauges which causes the fault.
