I was driving the other day and my car started to act up and then it died while i was driving. I replaced the battery and the altenator and the battery wont hold a charge and the new alt was only putting out 12.5 volts. Went back to autozone and swapped altenator and my battery still wont hold charge and alt not putting out proper voltage. had new alt tested before i installed it and it was good. Anyone with any ideas. Honda said it is possibly a wiring issue...

 

check your belts also.

 

belts are only a couple of months old. still in good shape

 

how old is your vehicle?
If you have voltmeter, check the voltage on the battery and start the car.
it should jump up to around 13.5v. If it's not, it's not charging. Or if not, it could just be corrosion on connection.
take it to autoshop, would help a lot if someone actually take a look under the hood.

 

Could be due to a faulty alternator. Have it checked.

 

i have put two altenators in it....the altenator now tested good before i put it in...i think it is a wiring issue because the altenator is not putting out...

 

found the problem....was a 15 amp ecu fuse...hope that works...

 

Hey man, see the belt tension. if you keep it loose or keep it too tight these kind of things happen.
