KA24DE Charging Issues - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey guys, so I have a KA24E car I installed a DE swap into. The whole car is running and driving perfectly, other than my charging system isn't working. My alternator is putting out 15-16v but it's not charging the battery at all. It's just reading 12v.

I did a battery relocation kit because I plan on boosting my car so I wanted the extra room in the engine bay. I'm not sure if that was the issue because I did that before I finished the swap.

In the link I've posted a couple pictures of the wiring to the T junction box just too see people's opinions if I'm dumb or not lol.

Thanks for any and all help!

Well...if ur alternator is putting out 15/16v thats high

But sounds like you have a connection issues.

Should have a thick guage wire 0/2/4/6 feed from main battery terminal location , then ran to the new battery location.

Then same gauge wire 0/2/4/6 to a solid ground location. (Cleaned, sanded) like to use a spot on the unibody frame.

I've ran 0 gauge wire for positive/negative cable. Every ground in the car has been sanded to bare metal since I was having starting issues before, which have now been well sorted out.

Your reading 15 volts off the stud of the alternator?

Off of the wire coming from the alternator.
