Just had a new experience with an electrical system interaction with an ignition system. I was wondering if anyone could explain how ignition timing could have an effect on the charging system. I've had flickering lights and a surging blower motor since I've owned the 76 aspen. I've also been fighting pinging under load at low to moderate rpm. This week I gave up on the timing marks being accurate and retarded the timing 2°. After I adjusted the timing I noticed the ammeter and my cigarette lighter voltmeter were rock solid. It even charges at 14.4 volts at idle now. It struggled to hit 14v previously and was erratic to say the least. Why would ignition timing have any effect on the charging system? So far the pinging is gone also. Any ideas? Experience with this type of relationship? Just curious. Thanks and have a great day!
