phildirt Posted April 30, 2014 Share Posted April 30, 2014 In the Wiki section of this site (page 5) there is a typical wiring diagram for the R (including the RW) series of trucks. It will give you the basics.Buy a Power Probe Hook. It was invented by a guy trouble shooting the wiring in a SuperLiner. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/35563-85-fuel-sender-no-power-at-guageor-wires-at-tankwhats-the-problem/#findComment-243777 Share on other sites More sharing options...
leversole Posted April 30, 2014 Share Posted April 30, 2014 Power for the gauge comes from a circuit breaker...gets power when the ignition is on...guage is a variable resistor to ground. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/35563-85-fuel-sender-no-power-at-guageor-wires-at-tankwhats-the-problem/#findComment-243779 Share on other sites More sharing options...
slingblade Posted April 30, 2014 Author Share Posted April 30, 2014 great advice youall,,spent all day fixing lights and undoing butcher type work under the dash by mechanics too lazy to find the problem,just run a bypass circuit to get it back up,,its a nice truck with individual differential guages,trans temp,motor etc,another thing ive found is the reverse lights dont work,someone put a toggle switch on the dash to operate,,isnt it just a switch on the top of the trans?i found it but nothing when i applied power to it to see if the reverse alarm worked,this may take a few days to unscrew,,thanks for all the great tips Quote Link to comment https://www.bigmacktrucks.com/topic/35563-85-fuel-sender-no-power-at-guageor-wires-at-tankwhats-the-problem/#findComment-243799 Share on other sites More sharing options...
