I broke the oil temp sensor, and Megan said they don't have spare parts, and that was a wierd request to need another sensor. What I'm wondering is what is the voltage ouput to gauge reading? It's rather odd that the supplier does not know, but I guess you get what you pay for. If anyone has done a calibration on these gauges, and or knows what common oil temp sensor exchanges with theirs, I'd love to know all about it :)
