Lifted the cab today and I think I found the problem. Good news is that the mechanic that fixed it already ran the extra ground and changed out the press fittings for nuts and proper wire ends. When I put the test light to the Ignition pole it had 12 volts keyed, nothing with the key off.... seemed right. When I put the test light on the Sender pole, the light glowed dim and got brighter as the gauge went up.... hmmm. The other day when I tried that at the tank, I didn't see a light. Retried it today inside and I did. Started checking the wire to the sender and found a bare spot where it had touched the tach. All my senders seem to move the ohmmeter up and down at the same rate, so I've probably got 3 good ones here. Gauge is back up to full (tank is fairly high) and it was sitting at E before, so if the sender isn't fried, I'm hoping it's all good to go. Cleaned up the grounds and made one new common one under the dash for the lower panel, lights and gauges, put one at the tank sender and did the usual cleaning under the shifter levers while I had things open. Should be good to go for another 40 yrs?
