Bugsy finally left the garage this evening after I got a chance to replace the leaky heater valve. Started right up after missing many, many months of driving as cottage project has occupied all spare time and thoughts.

Everything runnig fine until I noticed that at tach has decided to quit working. Checked coil connections and all tight there. Can someone tell me which color wire goes to the tach before I stand on my head to clean up connections under the dash. Don't want to bereak something that is currently working.Thanks in advance.
 
Thnaks Ray,

OK looks like a White/White is the loop coming off of the coil. I'll try and get myself upside down and clean up the green which must have appeared on connectors.

Overnight my brain was working on this problem. Aren't there two wires connected to one side of the coil. One side goes to power and tach and the other to ground or something like that. Need to look again under the hood and pull out wiring diagrams.
 
The white wire from the coil goes to the tach then on to the ignition switch.
 
Took the white wire apart and cleaned the connection. Still not working. Unscewed the knurled knobs to take out the tach and voila, ground connection made once again and back to working. Thanks Ray!!!
