Temp Gauge Wiring...Kinda lost! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Howdy All,

Temp gauge on a '82 K30 W/ 454.

I've replaced the circut board on the back of the instrument cluster and also the Temp sending unit on the engine.

Turned on the ignition and checked the three gauge connectors on the cluster with a 12V tester and nuthin' on any of them.

Which one should be hot? I inspected the green lead from the temp sensor and everything seems fine, I'm just not getting power. Is it OK to prod the circut board with the tester? Should one of the leads supply 12V to the 3 clips that the gauge clips into?

I've searched the archives, but couldn't find anything on our style of truck.

Ideas?...Theories?... I don't want to blow anything in 90 degree heat while I'm dragging by bobcat around the neighborhood!

Scott
