Hmmmm......first off all, the pulsing sounds like the regulator cutting in and out. Typical of an old relay type regulator.
Since it is not the fan belt, maybe the pulley on the alternator shaft is loose, but that's uncommon.
Check all grounds....alternator ground and battery ground for example.
Charging check....engine off.....12 VDC across battery terminals....engine on at idle.....13.5 to 14.5 VDC at idle (not to worry if a bit outside of this range)
If voltmeter drops from 13.5 volts to 12 volts when engine is idling, then charging circuit is likely a problem.
I suspect the voltage regulator...other than as the car sits a lot, it may be merely a bad connection somewhere....often a bad ground.
Get yourself a multimeter and do some testing. Good luck. |
