Still haven't found a . . .

schematic of the unit. I'm pretty sure that your unit has a 'transistor' whereas the gauge pictured above does not.

But still would like to know how a 'resistor' can serve as a regulator. A resisitor is a linear device, so how it can function as non-linear device (as a transistor), escapes me.

If I come across a modern day schematic, I'll post it here. Glad you fixed your problem. It does appear that all oil gauges have a definite failure problem. Who'da thunk it????
