My alternator light comes on with ignition on, and stays on with engine running, and voltage stays at 12V regardless of rpm's. Was charging regularly at nearly 14V. The fan belt is in good order at spec tension. The alternator was reconditioned a couple of years ago and now has about 5,000 miles on it. The diode behind the gauge was also replaced, but I have had the gauge in and out a few times working on other issues - possibly damaging it(?)
Before removing the alternator for testing, could the diode behind the gauge be faulty preventing charging? If so, what is the spec of these diodes? Your suggestions will be welcome. |
