Guys I'm stumped. I've been trying to solve a problem with my temperature
sending unit for months without success.
Here's the deal. I dropped a Chevy 305 into my '56 truck. I hooked the wire
from the dashboard temperature gauge to the new temperature sending on the
re-built 305. As soon as the engine began warming-up the temp goes straight
to "hot". (By the way I installed an "after-market" sensor that says my
engine is running at 180 degrees.) A guy at the auto-parts store sold me
another sending unit that is a closer match to what I need to synch-up with
my original gauge. But the new sending unit still shows very close to hot
when the engine is running at normal temp.
I've bought two new sending units and while I'm getting closer I'n not there
yet. I don't mind trying things by "trial and error" but at $12.50 a shot
this is getting expensive and I might be buying several more sending units at
the rate I'm going.
Any ideas on how I might proceed? I like having all my original gauges
working properly without using any after market stuff if possible.
Thanks a lot.
