More 1050c questions this time will include the serial # which is Lu1050c005231. OP gauge is pegged and h20 doesn't register. Have continuity on both of the sending wires at sensor to gauge. 2 wires on the gauges assuming one is sender and one is ground. Hard to explain all we've tested but could use a wiring schematic or diagram to truly understand how the system works. Or any other advice on how it works would. Be great! Thanks in advance for your help. Jason.
Thanks for posting a serial number.
