Re: Cooling problem solved now what's wrong with my tach?
Unfortunately my checks and actions over the weekend didn't produce any positive results. My "extra" loose wire is the original temperature wire from the old sending unit. It wouldn't reach the oil pressure unit or the alternator and reattaching it to the new unit didn't change a thing. All the wires on the alternator are protected by a boot and all were intact. Nothing appeared amiss at the bellhousing/clutch neither so I'm back to square one. I'll recheck the wiring at the tach itself behind the ignition/start plate next time out although it all seemed fine when I first looked.
