masinoshane Posted June 8, 2023 Share Posted June 8, 2023 Having trouble finding out where the black wire to the actual sensor gauge is attached to the motor somewhere also when I turn the gauge dimmer switch knob down the light on the transmission temperature gauge gets brighter as the rest of the gauges go dim86 Seabreeze Quote Link to comment Share on other sites More sharing options...
REALLYRURAL Posted June 11, 2023 Share Posted June 11, 2023 Sounds like a ground issue. Broken or bad grounds can cause some funky things to happen. Might not solve your problem but checking all the grounds on a regular basis. Both ac and dc can prevent a bunch of problems Quote Link to comment Share on other sites More sharing options...

Also would the sensor be located on the side of the transmission oil Pan? Quote Link to comment Share on other sites More sharing options...

extech Posted June 22, 2023 Share Posted June 22, 2023 i don't see the symbol referred to. i would think g is ground, s is sender, and the other ignition. Quote Link to comment Share on other sites More sharing options...
extech Posted June 22, 2023 Share Posted June 22, 2023 do you have a test light or multimeter Quote Link to comment Share on other sites More sharing options...
masinoshane Posted June 22, 2023 Author Share Posted June 22, 2023 Just now, extech said: do you have a test light or multimeter Yea I've traced the wires down. He's got the light tied into the dimmer knob. But it works in reverse when you turn the dimmer down. The oil gauge gets brighter when the rest of the - lights get dim and then hes got another wire to a ground screw behind the dash Another wire hes pulling from a bundle Where the fuse for the radio comes out of. And severed wire coming from. I think the oil Pan sensor. It makes sense that they were connected together at 1 time Quote Link to comment Share on other sites More sharing options...
extech Posted June 22, 2023 Share Posted June 22, 2023 are you more concerned with the gauge or the light Quote Link to comment Share on other sites More sharing options...
extech Posted June 22, 2023 Share Posted June 22, 2023 looks like factory dimmer is on the ground side. turning the dimmer knob increases the resistance to ground- dimmer lights. Quote Link to comment Share on other sites More sharing options...

extech Posted June 22, 2023 Share Posted June 22, 2023 ok. the gauge has 3 wires. one is power. check each wire with key on. one will show 0 one should be battery v, the other may be less. disconnect either of the last 2. one of them will be battery v. reconnect and connect the other wire to ground. the gauge should go to it's upper limit. thats the wire going to the sender on the transmission if you connect your test light clamp lead to battery v when you probe the ground connection it will light if the wire is actually grounded. i know clear as mud Quote Link to comment Share on other sites More sharing options...
extech Posted June 22, 2023 Share Posted June 22, 2023 the gauge installer connected the light incorrectly. doesn't affect gauge operation Quote Link to comment Share on other sites More sharing options...

extech Posted June 23, 2023 Share Posted June 23, 2023 are there 2 wires for the light? i thought only one. if so that wire should go to any light power and not try to have a dimmer on it Quote Link to comment Share on other sites More sharing options...

extech Posted June 23, 2023 Share Posted June 23, 2023 yea i get it. put tape on each wire. label them. disconnect them. find the one that has power with key on. if using a test light connect the clamp to battery power and the probe to the other wires. one will light brightly. it goes to ground connection. the other wire goes to the sender connection. with power on, touching the sender connection with the test light (clamp grounded) the gauge will go to full hot. this tests the gauges ability to work. the sender (if working) will make the gauge move based on it's resistance to ground Quote Link to comment Share on other sites More sharing options...
