70 + voltage regulator issue
I'd first suspect the splices in the ignition wire (made for the modifcations), and also the alternator output wire where it connects at the firewall.
This is the factory wiring scheme.
You can change it to reflect the modifications made to your car.
If there is resistance at 'P', during high charging situations, the voltage at the battery and at the 'run' circuit (J2) will be lower than voltage the alternator is producing (stud terminal marked BATT).
When current flow is low, then the voltage loss due to resistance will be less.
V = I x R.
I = current. Low batteries demand lots of current.
When current increases, the voltage drop through the resistance increases.
