I've got two temperature gauges (was trying to prove that the first one was just wrong) wired into the sender in the coolant system, and both read wildly wrong, and not even by the same amounts.
Thought that was odd, so we swapped in a second sending unit, and got pretty much the same readings. We were confirming the temp with a temp gun and it never got above 80C
We did keep some data points comparing the values at a given time until it became clear that both gauges were just wildly off. I'm sure I could find that if it was important.
These really aren't complicated gauges to wire, Ignition, sender and ground, so if I'd wired something backwards it should just not work at all.
The only thing I can think of is the wires themselves? All we had was 14ga, but figured it should be fine even though the gauges asked for 18ga. Unless I just have two bad senders?
Any thoughts?
