Here some brief update...

After some hours troubleshooting the problem, I could have one good idea on where the problem is.

The problem is on Positive pole. The lights, panel and everything works fine when connect the battery positive to positive jump start pole under the hood.

Something is wrong between the positive battery cable, or positive line, between the starter and positive jump start pole.

My question now is: Could something burn inside the generator that is able to cut the positive circuit?


Thanks!

It would be unlikely.

Start at the battery positive terminal and work your way forward.
You know you have power at the battery, so test for voltage at the starter connection.
If you have voltage there, check to see if you have voltage at the hot post on the alternator.
Then check at the jump post...

Since you were working on the starter, that is the most likely place. If you can it may be worth posting a picture of the connections at the starter, on the off chance that you don't have it wired back correctly.

Look for the secondary red wire that runs forward from the starter solenoid. It should also have (what was once) the white wire for the staretr solenoid trigger. The large red wire connects to the sane point where the larger wire from the battery connects. You would have disassembled this connection when replacing the starter, and should have reconnected it when the starter went back in. This is the most likely failure point, given the work you just did. The wires are in a harness that runs across the crossmember under and behind the steering rack, towards the driver's side. It runs over that crossmember, where it it is secured with a strap clamp. then forward to connect to the positive terminal (B+) at the alternator.

1) Verify that the secondary red wire is connected at the starter, on the same post where you connected the battery cable. If that connection is correct, move forward to the alternator.

2) The alternator hangs from the lower front of the engine on the driver's side. On my later car, there's a plastic housing for air circulation covering the rear of the alternator. The air hose slides off, and the cover can be removed after removing the nuts on the through-bolts that hold the alternator together. Slide the cover back, so you can test the voltage at the B+ terminal. This point is connected to the starter B+ by that secondary red wire.

If the starter end of the secondary wire is correctly connected at the starter end, and you do not have voltage at the B+ terminal on the alternator, there's a fault in the wiring between starter and alternator. If there is voltage at the alternator B+, and no voltage at the jump post, there's a fault in the front-of-engine wiring harness that runs between the alternator and engine sensors, to the 14-pin connector and the jump post.

Thank you guys for the ideas!

I´ll try them tomorrow and let you know.

Thank you guys who helped!

Problem solved and learned a lot! The alternator wire was cracked. It was looking good but failed on continuity tests.

I´ll use this oportunity to rebuild all electrical connections at starter circuit.

Thanks again!
