Hello,
My old Pontiacs have about bit the dust.
My wife's car is struggling, as the title says. An intermittent battery warning light while driving. An intermittent no crank condition that follows the battery light; however if the car sits for a few hours afterward it will start no problem.
I have not been able to duplicate this problem, it has only happened to her.
I have replaced the original alternator because I believed the diodes in the regulator were failing causing a battery issue however this has done nothing to solve the problem.
With the car running, my DMM shows about 14 volts DC at the battery terminals. With the car running, my DMM shows between 10-30 volts AC at the battery terminals. Are the diodes on my new alternator bad?
I honestly don't know what the problem is here.
