A week ago I had trouble starting my 914-4. This was after driving it for an hour, and then leaving it in my garage for half a day. I started it by pushing it. Drove it for an hour and parked it in the underground garage.
Today, tried to start it, again same issue. Won't start. Took it to a battery shop, where they measured the battery and said it looked good, but that my charging voltage is low (they measured 13.1 volts, even with me revving the engine). Drove it home, measured again at home the voltage at battery with the engine revved up, 12.6 volts. Tried replacing the voltage regulator (had a spare one at home), same exact result. Before I launch into replacing the alternator, what else should I check, and in what order? What are easy steps of things to check? Thanks, Andrei. |
