Hello, everyone.
I'd purchased a used fuel gauge for my TR3A. Trouble is, the fuse to F3/F4
kept blowing. I've isolated it to the gauge by disconnecting output to the
fuel gauge and running an inline fuse from a direct power source, bypassing
the stabilizer. With just the fuel gauge hooked up, fuses blow every time.
When I swap leads on the gauge, with the green wire power going to drivers
side, and output (green/black) to the passenger side, the fuse doesn't blow,
but it registers full, even if I've disconnected the fuel tank sending unit or
swapped the ground with the green/black wire there.
I tend to think this is a fuel gauge problem, but I can't figure out why a
short to ground within the gauge would not short regardless where the leads
are attached, since really a gauge is only a simple resister, isn't it?
Thanks, everyone.
