1988 Honda si Alternator Problem

I have an excellent independent Honda mechanic. My Alternator light is on. He has checked the alternator belts, brushes, etc and the alternator is not charging the battery. He has replaced the alternator with a new factory replacement alternator and it is not charging the battery either. He showed me the wiring diagram for the model and it shows a single wire from the alternator (the voltage regulator, etc) self contained in the alternator. I believe the wire went to the alternator light indicating when it is charging. The diagram does not show, nor can he find any description as to whether the voltage should be +12v or ground. Do you know?

Thanks
Bob in Charlotte

Could be the alternator bearings, there are two of them, one inside in the front, one inside in the back.
You can sometimes tell by using a mechanic's stethoscope, which is a long screwdriver or an long thin stick.
Place one end on the alternator (when the motor is running) and the other end in your good ear.
A bad bearing will scream at you.
The other think more likely is a worn out belt.
They make an awful noise sometime when the rubber gets hard.
The can chatter, squawk, and other sounds mimicking the alternator.
Also, be sure to check the belt for cracks on the inside surface.
Changing the belt is cheaper that replacing the alternator, if you'd care to try the least expensive fix first, and you still aren't sure.

Check the alternator belt. It needs to be tight. A parts store can check your alternator on your car for voltage output. A loose belt or a weak alternator will cause your problem.

Best way to replace an alternator on a 1988 honda accord


Disconnect battery.
Remove under engine shroud if it's still there.
The alternator is at the front of the engine down low on the radiator side.
Loosen drive belt, the alternator can be removed by patient use of a 14mm wrench, the wires should be removed before dropping the alternator out. Frankly I forget whether they are in a jack or screwed on.
It is necessary to turn the alternator sideways to get it out.
Have fun!

How do I change the alternator belt in my 1999 Excel (list did not have the year)?


hi mate,your problem is fairly easy to fix-----remove the plastic under tray on the drivers side,from underneath, undo the main alternator bolt,just enough to move the alternator, now from the top undo the belt tension adjustment locking bolt,then back off the tension adjuster itself until the alternator belt is loose and can slip off the pulleys-----fitting your new belt is the reverse to this. all the best.

New alternator and battery battery light stays on and car dies


Have you checked the alternator fuse? The regulator needs power from the fuse to turn on the alternator. The old alternator could have blown the fuse.
