Hey guys. I'm new here and am hoping someone can point me in the right direction with a couple of strange electrical things on an e30 318i I've just done an engine and manual transmission swap on. All the gauges work except the temp guage. When I earth out the wire at the sender there is no response, so I'm thinking maybe si batteries? It's just strange because the tacho works fine. Also, the windscreen washer is reading a constant 8 volts at the pump, and switches up to 12 volts when you pull the wash lever. Any ideas?
