Ok seems simple. Voltage light on dash on. Battery dies. Replaced voltage regulator with a wells VR650. Light on dash off. All seems good. But voltmeter shows the voltage dropping the longer the car runs until it dies. Voltage does not change regardless of engine speed.
Put the old regulator back on. Light on dash stays on regardless of engine speed. But voltmeter shows an increase in voltage with engine speed. I have not gotten the battery charged yet to see if running the engine discharges the battery. I am at a loss as to what try next. |

In post #15, you mentioned that the car died when the cable was removed. Not good for alternators! (IMG:style_emoticons/default/sad.gif)

QUOTE(Tom @ May 10 2013, 11:31 AM)  In post #15, you mentioned that the car died when the cable was removed. Not good for alternators! (IMG:style_emoticons/default/sad.gif) Tom Tom I am no expert and I may have this all wrong but for my car which lacks FI, it should have no impact on the electrical system or the alternator. The voltage regulator is between the alternator and the cars electrical systems so there is no posibility of a surge. So I was taught that until the age of computer controlled systems, that the alternator does not really care what is happening with the rest of the car. It spits out power as demanded and in relation to engine speed. Just to be clear, I stated my understanding and ask the following question because I want to learn, not to be a smart ass in anyway. I have learned so much since finding this forum that I just have to keep asking questions. Ok so what am I missing? Is it something specific to all alternators or just the 914 system? |
