Hi Guys On Sunday I went racing and had to pull out because I thought that my engine was over-heating. I should have realised that it wasn't at 250F, but anyway I was giving it a bit of a flogging and immediately before that I noticed two stutters in the engine. Anyway, I found that the sender wire for the temp gauge had touched the water pump and gone to the core (which is + and therefore live). I have fixed this, but my tachometer is reading all over the place. On start-up it goes straight to 4-5000 rpm. If I rev the engine the tacho reading falls and then climbs again. The engine is happy and running well. I don't even know whether these two things are related, as I am sure that the tacho failed to read correctly before the temp gauge went up full. I think that the 2 misses were as a result of the live wire touching the engine though. Any suggestions? I feel that it may be a blown resistor. But the falling reading on revving has me miffed!
