he headlights on -- but does happen every time. Any ideas how to troublesh oot it?
ition a few degrees after driving a half hour or more with the headlights o n. Then I cleaned all the connections in the starting systems from batter y terminal to hot connections and grounds, and the problem stopped.
no problem indicated. I left the lights on for 20 minutes while in the sto re. Then when I started, the battery needle start oscillating from 50% to
100% regularly, and the battery warning light started blinking off and on.he parking lights so I could drive the 2 miles home. After driving about 1 /2 mile the oscillating and flashing stopped.
all is back to normal for now.
me kind of low voltage and the swinging and flashing was an attention-gette r, and not the actual reading.
But if I find a nice BBQ on sale, all bets are off.
No time to check at the alternator tonight, but here's some voltages at th e battery terminal.... Turn signals seems to cause the cycling tonight, alt hough I have seen it cycling with just the lights on.
You sure your meter isn't busted? Fully charged battery is just 12.7V
Those look like they are about 1V high too. I suspect your meter is off. You could try a fresh 9V battery to check, that should be around 9 .5V.
Assuming the meter is off, I don't see anything unusual in your readings. It's not dropping anywhere that would indicate a charging problem that would put the dash light on. Exactly what puts the light on varies from car to car. Some use the old method, where it's essentially a light bulb tied to 12V on one end, the other goes to the alternator. If the voltage there drops low, the bulb lights up. Others now have the computer monitoring the voltage at the alternator and it decides when to turn the light on.
