Alternator not charging battery
Alternator is good and the battery is good but
there's something not letting it charge I've had both
check and check them myself check all the fuses
no wires but yet it will shut off about a mile down
The car is shutting off because it had ben running off the battery until there is not enough juice left in the battery. So ya, gonna have to check the wire that runs to the battery from the alternator & the small wire that plugs into the alternator. Lot of times that plugin will go bad.
Are you talking about the little brown wire
That plugs into the alternator. That plugin can go bad, they make a replacement.
Alright just making it clear, thanks!
What is that wire for?
It runs power to the voltage regulator. Turns on the alternator so to speak.
I changed that wire and all the other wires and plugs to the alternator but its still draining the battery can't other ideas
Is the alternator working, or is something draining the battery with the key off? You changed you terminology.
No battery stays changed with key off but its drains like crazy then stays at 10.91
Ok thats because the alternator is still not charging and the car is just running off of the battery juice. So, you know the alternator works. It has to be in the wiring some where. I know on my vehicle there is a fuse for the air bag, and for the gauges. If one of these are not in place, my vehicle will not charge. Otherwise without being there to see, I don't know. But I will be thinking of anything all day for you.
Well I dontbknow if this will help but the battery light by the gauges is on and the check engine light will come on and off. But thanks for helping me
Did you ever figure this out cause I'm have same problem
Me too I am stumped
I had the same problem after 3 alternators,testing every wire even the fuse. When I replaced the 20 amp fuse I found that it wasn'tmaking a connection,so I bent the tabs closer and my charging system started working.
What 20 amp fuse? What is it called in the fuse box?
Starter is grouding out if you got batt and alter checked take get it checked
Check the voltage regulator
my battery is not charging like it should. it just died on me coming home had to be jumped and then all my gauges started going haywire, however i have battery charger on it now it is way low
can anyone tell me whats the problem here i have a 1996 f150 truck
