On the way back from the beach I went to go turn on my lights and the trans temp gauges goes right to 320 and I turn the lights off and it goes back down to 160 at what it was when the lights were off.
So I get home to look at all my wiring and it looks good. I turn my head lights on and I hear a buzzing noise and its coming from the trans temp gauge. What could be the problem? The boost gauge is fine and the trans temp only works when the lights are off otherwise it will go up not read right and say if im at 140 degrees it will read 190 and its really got me worried that something might be up with it.
The gauges are Stewart Warner Maximum performance series Boost, EGT and Trans temp. Any help will be appreciated!
I was having a similar issue with my Isspro tranny guge, used to jump all over the place, weather lights were on or not. Go over ALL your wiring. back of gauges, ground connection, and other connections...i just jiggled a few wires around D/C and R/C wires and havent had a problem with it since
