Hello, the name is John. I am a driver for a non profit org in fort
We currently have a 1986 chevy suburban we haul teens around in.
We are having a problem with all of the gauges, none of them are
reading anything, except the fuel which jumps and is never truley
accurate, we've already stopped once w/o fuel, and there is also an
after market oil temp guage that was installed and that works well. I
was wondering if anyone could put me in the right direction as where
to start repairing , or what wires to start looking at first. Thanks
