Re: Engine Temperature Guage Inoperative - Where to Start?
Posted by HH56 On 2012/5/22 14:03:55
If oil and gas work, instrument regulator & fuse are OK. Remove the wire from sender and ground it while someone is watching the gauge. If it starts to move toward hot, gauge and wire are OK and problem is sender or ground to sender. If no movement, then wire or gauge. Don't leave the wire grounded longer than it takes to have gauge move to hot.
Senders are a failure item & all the vendors have new. Don't know offhand of a proven aftermarket replacement sender available locally but have an idea of one. Specs at least look like a possibility. We need 90-100 ohms cold and 10 or so hot. This one is good hot, but not sure on cold. IIRC, someone might have tried one already but if you want to try as well, it is an Echlin TS 6464 from Napa at about $12.
