Greg, you posted while I was posting LOL. Wife went down to beautiful Tennesse to visit parents. Wish I could go but work wouldn't allow it. Suure would like to try that Kama out!!!!!!!Getting back to this electrical problem. These cluster gauge sets can be confusing. I have the same cluster set-up, wish I had the individual guages. Putting all the eggs in one basket so to speak. We'll I "think" the tach/hour meter is a separate circuit driven by the sensor in the bellhousing. I believe the rest of the gauges, etc are all separate DC circuits.
I know I had that bad connector and checked it with my digital meter. It was AC. I'm getting older but not totally senile yet(maybe wife would disagree with that). I just do this stuff so fast out of instinct and do the fix.
I think it was Paul Wilkie, or DIY guy that had problem. We went thru this on the old, old old, board. or was it 5 old boards ago?
When I AC I'm talking a 2 wire signal generator which is a low voltage here. Its a alternating current. High/low switching from positive to negative. Many older equipment used ac type drive tachs, etc. real old technology. Good grief(old age) I still remember the specs for GM products for the distributor pick-up coil. (500 to 1500 Ohms resistance, must be able to put out 1 volt AC) It was not the voltage but the frequency of the cycles. Of course it was changed to a DC voltage thru a DC signal converter inside the ignition module.
I think we are both really saying the same thing but termonology/semantics gets in the way. True, AC is high/low, but the frequency of high/low is directly proportional to its output. Digital is a more on/off signal. In order for a AC signal to be used "accurately" the signal must be cleaned/ clipped/ changed to a more true on/off 0/1 so it can be used in a digital binary system. We are talking old old tech on these China systems so this isn't a factor yet,,,,,,,,,until the tree huggers want computers on our tractors. Don't laugh,,, its gonna come one day.
I always like conversing with Greg,,,, one hellava nice, knowegable guy and always willing to help others.
