Engine temp goes up significantly when lights turned on
benracing123:
Hey guys thought I’d bring it to the forums because I’m stumped, I have a digital dash kit that’s been in for some time now and recently when I turn the lights on in the truck the temp will go from 195-220 within 10 seconds I don’t know if I should even think to trust the guage or of my thermostat is fried. If anyone knows anything like this please help

What gauges are you running? Sounds like you have a poor gauge/body ground.

They are the intelirronix guages but I have them all grounded to the motor

The intellitronix gauges are crap and depending on what ones you got, they have major issues. Nevertheless, make sure nothing is touching and check all connections.

Pretty sure it's electric. Tstats are mechanical.
Does it stay pegged at 220? Or does it fluctuate?
