Hello,

1989 2WD van. Alternator, oil, and radiator lights all come on while driving. Intermittent at first, now all the time. If I turn off the engine and start it back up, problem will not exhibit for several seconds, or perhaps not until I rev it above idle. Voltmeter on the battery shows charging at 16 volts at idle, over 17 when revved.

Could this be anything OTHER than the regulator?

Thanks
Andy
