<VV> Re: re;thermister

[Michael Kovacs]

I checked the continuity to the guage. It pegs at 600 when  the wire is grounded. Then "bench tested" all of thermisters. They will also peg the needle when carefully heated with a propane torch. A match did nothing, the hair dryer did nothing.
   
   I'll need a high speed cruise to see if there is something to be concerned with. I'm really just looking for a data base for comparison while driving.

  btw,since you've got a few,put one in the right head and compare the gauge readings...a thin coat of neversieze on the thds...unless you don't want to risk shearing the snap sw off...don't ask...Tom..//

   About 5k at room,  and just touching the bulb will start to lower the resistance. I checked all of them and will pick one. Thanks. I'll first check the continuity of the car wiring by grounding the thermistor wire before replacing anything. 
   
   Like they taught us in the USAF, check the simple stuff first, like a burned out warning light, before trying to find out what is wrong with the circuit.
