I have a 1988 5000 CS Turbo Quattro that was having electrical problems. At first there seem to be no power coming from the battery so the mechanic installed a voltage regulator and that seem to work, but today, I was in traffic at a stop light with the wipers/lights/heater/radio going and the low battery warning came on. I turned everything off and it went away. As soon as traffic moved I turned it on and when in motion the warning did not come back.
Do I need a (gulp) new alternator?
Thanks in advance!
