2010 Maxima Overcharging Problem

Postby Remix919 » Fri Jan 11, 2019 3:26 pm

Hello everyone,

My 2010 Maxima recently developed an overcharging problem that has been quite the gremlin. It is overcharging at about 15-15.2v, sometimes fluctuating between 14.5-15.2v. I have replaced the alternator with a Denso one, I have checked and cleaned the ground wire to chassis and tranny. I've checked the fusible link at the top of the power cable. Still the exact same issue, been searching around but haven't found anything quite like my problem. Any ideas?

If the battery is old and about to die it might do that. Not ever 'filling up' to force charging system to work harder.

Sorry, forgot to mention that I replaced the battery as well, I put a cheap walmart value battery in the car, not an OEM spec one, but I don't think that should matter?

Shouldn't.

What exactly caused you to 'discover' the issue? I ask because some cars intentionally charge pretty close to that. Meaning if you simply discovered it by checking when you hadn't before may not be wrong.

Normally overcharging is a regulator or sometimes a ground issue, not many things to cause it.
