Why does the temperature gauge not work?
I would assume your question is ‘My temp gauge doesn’t work’..First off the system consists of just two parts, the gauge itself, and second ,the “sender”…the sender gives a signal as a variable resistance according to temperature to the gauge…first find the location of the sender (The size & shape of a sparkplug, sometimes smaller)it has just one or two electrical contacts(wires)…it is screwed into the block or head to sense the coolant temp…correctly identify it, turn the ignition “On” removing the connecter will fool it into thinking its COLD or HOT, BRIEFLY jump a wire across the two wires (Or short a one wire version to ground) you should be able to get the gauge to swing one way or another..if not you may have a bad gauge or a wiring issue. If it does swing, the sender is bad. _____________________________________________________________________________________Rick………
