Temp Guage
Hey everyone, need some advise before I go break out the wallet.. My aftermarket temp gauge just stopped the other night when she overheated.. It is getting power as the light still comes on and the connection on my intake seems solid..
Is there a way to trouble shoot for these or should I just scrap it and buy a new one?
Thanks,

Assuming it's an electrical sensor and not a Bourdan tube (long skinny tube from the sensor site all the way to the gauge) - probably one wire to the sensor? If so, check resistance through the sensor - connect the + wire of the multimeter to a 12+ line, then the ground wire of the multimeter to the wire post on the sensor, engine cold. Turn the engine on, and as it heats up you should see the resistance changing. If it doesn't, your sensor is probably shot. Think that should work. On a Ford factory gauge I think I read elsewhere that they go from 20-70 ohm resistance, aftermarket I have no idea.
