What would cause my EGT gauge to start moving backwards as it warms up got the autometer phantom series got red wire on acessories and black wire grounded and the yellow and black are correct to yellow and black on the gauge and to the probe just wondering if anyone else has had this problem

HELP ITS DRIVING ME NUTS

 

Elaborate. I don't think anyone understands "moving backwards"...

 

well instead of the needle on the gauge moving upwards toward the numbers it goes down or back wards the opposite way it should be moving as if i had the wires backwards BUT I DONT

 

Did it ever work correctly?

The voltage should only flow one direction across the junction.

 

i bought it new just hooked it up and it dosent work and i dont know if this is a sign of a fucked up gauge or what im going to go over the wiring tommorow and if its all good then ill just get rid of it.

 

Sounds like it's hooked backwards.
