Hi and Welcome to Just Answer! My name is XXXXX XXXXX X will do my best to help.
alternator needs voltage to activate, just a minute to open wiring diagram
Where does the voltage come from and at which pin on the alternator?
you need to have voltage on yellow white wire
all the time
`Where does it originate?
it comes from fuse 16-15A located in power distribution box
it has to be connected to A terminal
We checked that fuse and it is good. With the engine not running we disconnected the connector and checked that pin and it read 12V.
It is not possible to connect that connector backwards as it is keyed.
if this is ok, there is fusible link on the black orange wire between alternator and battery
have you checked resistance on that cable?
We checked for continuity between the terminal on the back of the alternator (blk/org) and the connection to the starter relay and it was good.
can you use booster cable and by pass that cable
clamp on alternator where black and orange wire goes and the other end on battery positive
We could try that but what will that accomplish?
if alternator is good and you have power to alternator, then it has to be that cable
it will not cost you to check
it will take few minutes only
We connected the two and the voltage on the battery jumped to 13.5! I think we have our culprit!
ok, so you need to fix that fusible link or replace that cable
We will replace the fuse link. Thanks. I suppose I hit accept now?
You are Welcome!
thank you for using just answer and accepting my answer
Is there another fee for this question or is this a part of the original issue and therefore covered under the original fee?
alternator has all built inside, you install it and when you have all power and all attached according to diagram it has to work if your connections are good. if wiring is good check if alternator did got damaged during working process, there is nothing else. if you have overloaded the circuit you have blown the diodes in voltage regulator.
