Re: TEMP GUAGE
Here's a good way to isolate your problem. With a multimeter, verify you have battery voltage between the I(12v) and G(ground) terminals on the gauge, even a cheap test light can accomplish this.<br /><br />If you don't have voltage there, simply rewire the I and G to another gauge that is functioning.<br /><br />If you do have voltage there, remove the sender wire from the gauge. Then short the S(sender) terminal on the gauge to the G terminal on the gauge. The gauge should peg all the way to the right. If the gauge does this, it is good to go. If not, it's the gauge.<br /><br />If it does, the problem is with the sender or the wire from the sender to the gauge. A guage completely pegged to the left is a symptom of an "open sender" (the gauge doesn't see the sender).<br /><br />Also verify there is no teflon tape or pipe dope on the threads of the sender. The body of the sender requires a ground from the engine. If there is pipe sealer on the threads there is no path from ground for the current to travel through the sender to the gauge.<br /><br />Good luck.
