Unexpected dash warning light illumination
Last night while running an errand, the dash warning lamps for temp, generator and fuel all unexpectedly came on. The car had only been running for three mins, so it wasn't overheating, the fuel gauge still displayed a correct level, and as near as I could tell from visual indicators ie dim dashlights/headlights, the system wasn't discharging. The car has console gauges with the low fuel sender, new American Autowire harnesses, and I have wired in the temp light on the dash to work as a back-up to the temp gauge. The wire to the coolant sensor in the cylinder heads was not hooked up as the sender does not have the correct resistance to accurately run the gauge and light in tandem. I haven't gotten around to installing two separate sensors, but that's a job for another day. Anyone seen this before or have any suggestions?
