80LS1T Posted July 22, 2003 Share Posted July 22, 2003 Ok I have a Autometer Phatom series temp. gauge in my car. I have the sender hooked up to the thermostat housing on my LT1. It worked like 2 weeks ago but now it doesnt seem to work? When I take it out and heat it up with a cigarett lighter(I dont somke ) it works? What am I missing here? Could the thermostat housing be coroded(sp?) so bad that its not making a connection? All I know is that it worked 2 weeks ago! Guy Quote Link to comment Share on other sites More sharing options...
Tim240z Posted July 22, 2003 Share Posted July 22, 2003 Well the LT1 sender by the thermostat is for the PCm signal. The one in the odd bank head is for the gauge. Don't know if it makes a difference, but put your sender in a tin of boiling water and check the sender that way. Tim Quote Link to comment Share on other sites More sharing options...
80LS1T Posted July 22, 2003 Author Share Posted July 22, 2003 Actually I just thought of something....my voltmeter isnt working either and they are both powered by the same 12V signal? Hmmmm....I wonder if that has anything to do with it? Guy Quote Link to comment Share on other sites More sharing options...
80LS1T Posted July 22, 2003 Author Share Posted July 22, 2003 Oh and I know my sender is ok because when I ground it, it pegs over to 260(all the way hot) Guy Quote Link to comment Share on other sites More sharing options...

80LS1T Posted July 23, 2003 Author Share Posted July 23, 2003 Well Im not sure what the heck is going on? I had it working again tonight but it seems like everytime I run the car it doesnt work, only when the car is shut off and key on. I know I am getting voltage to the gauge, the wire from the send to the gauge is good and no brakes in the wire, the ground is also good! I think I need a new sending unit? I just oredered one from JEGS and it should be here by the weekend. It was only $14.00 so I figured I would try it. It just seems like when ever I fiddle arount with the sending unit it works then when I stop touching it it doesnt! Guy Quote Link to comment Share on other sites More sharing options...
