Re: Battery charge light will not turn off
So the diagrams in the shop manual for the alternator terminals and the alternator connector are pretty crap and I thought the diagrams were of the alternator terminals but they are actually of the terminals in the alternator connector. I realised when the result I was getting on the multimeter from S at the under-hood fuse box wasn't corresponding with the result I got yesterday from S on the alternator connector. These are the correct test results from yesterday of the alternator terminals and alternator connector.
Alternator terminals (grounded to engine/grounded to battery negative post): L: Nil/6.2 volts FR: 3 volts/3 volts IG: Nil/6.4 volts S: Nil/6 volts Alternator connector (grounded to engine/grounded to battery negative post): L: 11.5/11.52 volts FR: 4.58 volts/4.58 volts IG: 11.49/11.5 volts S: 11.81/11.82 volts I don't know if the FR circuit to the ECU is 12 volts, but if it is then there appears to be a problem somewhere in the FR circuit. To rule out the FR terminal in the alternator connector being bad, I followed it's WHT/RED wire to it's socket at the top right hand side of the engine bay, disconnected the connector that connects to the socket and then tested the FR terminal inside the connector. https://i.ibb.co/0Y1ShrJ/FR-at-top-r...-connector.png These are the results: FR at alternator connector: 4.55 volts FR at top right hand side engine bay connector: 4.94 volts What do others think? |

Re: Battery charge light will not turn off
You've done lots of testing. It appears you have convinced yourself the Alternator is good. Until you test that alternator, the numbers won't mean anything. The first step in testing the charging system is an alternator test. Either running or pull it and bench test it.

Re: Battery charge light will not turn off
Never mind, I the FR voltage is fine.
I can now confirm the car is good and the alternator is fucked. The place I got it from is sending out another one to me. Thanks aleekat & Stealthee for the help. |

Re: Battery charge light will not turn off
That's good news. Since you're probably getting another Reman. I would bench test it before install.
