Warren,
The connector for the fan thermostat had just gotten loose after all these years and a good mash with a pair of pliers has it tight now. If it comes off again, I will replace it as that is just a 5 minute job and very easy to get to as I mounted my thermostat where I could get to it easily. As for the power lead from the alternator to the regulator, that is easy to get to as it is right on top of my firewall, but I don't know if I can buy those plugs or not if it pulls out again. I may just try to jury rig something to hold it in the plug. Sure ruined what could have been the best day I have had for a long time. As for the age thing, old age and shaky motors will cause all kinds of problems.
