Overcharging

Volaredon,
Back as a young mechanic, the boss used to have us replace the Ballast Resistors on most any Chrysler product that was a "no start".
The thought was that if it wasnt bad then, it will bad be later.
A sort of cheap preventive maintenance.
They seemed to go bad quite often back then.

That is why I have carried a spare ballast in my car since 1970 they die at the worst times , but are an easy fix
