Help battery over charge

pokeyl

After picking up the new alternator, I did not want to change it as the GTM supercharger kit makes it an all day job. So before I started I looked for other causes...

Looking at the wiring "Charging System" (CHR-15) I inspectied the fuses, found one blown. I have a FSM and it never even talks about a fuse on the S termanal. Only if you are missing voltage, repair wiring. Nissan did not make this manual easy to navigate.

The other part of troulbleshooting this was the "Brake Lite" was on as well. I also looked at the wiring for that. It is just the switch and the LED. Not connected to the other LED in any wey that you can see in the wiring. After that you have to be getting power to the LED to light both of them from some other path.

I still can't find that path but if I could see the inside of the LED's waring lites I think you would find the two on the same board without any power isolation. Power is sitting on the brake looking for a ground and the battery is the same. The groung came from the voltage regulator when the power was not supplied to termial "S"???

We will never know, but if you wasnted to see what I did, just pull the 10A fuse. I hope this helps other someday. I have to take the alternator back now, full refund from Carquest.
