SOURCE: changed alternator in 2000 mpv battery comes on and off

Check the large fusible link labeled ALT in the under hood fuse box. If this fuse gets blown, the alternator wont be able to charge even if it IS new,because the ALT circuit is open.

SOURCE: Battery dosn't charge, alternator/voltage adapter test's good.

Did you test the Alternator on or off the truck? It might be a problem with the control system to the Alternator. The regulator need a battery feed to work, It is usually ran through an alternator fuse.

2001 Mazda MPV, have replaced Alternator, but battery light keeps coming on. When negative terminal wire is removed the engine dies, but using meter the voltage output is around 13.85-14. Checked all...


Removing either battery cable, thereby taking the battery out of the circuit, with the engine running can cause the alternator to charge full tilt and destroy sensitive micro volt (computer controlled) components; and I've seen wiring harnesses go up in flame from it. You may have a module problem.

I own a 2000 mazda mpv, battery light was on and a changed an alternator and light is still on and not charging my battery. What could be the cause?


you probably got a defective alternator...this happens more than it should...perform alternator output test at 2000 rpm you should make 13.6 volts and up to 100 amps of power under load.

Replaced loose battery terminal and alternator light is now on


If an alternator overcharges, it will most probably spit out electrolyte from the filler caps or vents when run for a time. It may also become quite hot to touch.
Providing the engine is starting OK, and the charge warning light on the panel is not alight or flashing on and off, what you need to do is have a voltage check done on the battery with the engine running. If the alternator is OK, the voltage should be in the vicinity of 13.5- 14.0 volts (13.8 is the accepted "standard").
Any higher, it could indeed be overcharging.
Turning on the headlights should not materially change this voltage.
If the voltage is only around 12V or even less, turn on the headlights, and observe it again.
A low voltage can mean the alternator is not charging.

How do I replace alternator in mazda mpv 2000?


Typically an alternator is an easy fix. It requires removal of the belt from the engine running it, and a few bolts that attach it to the engine.

Because of the engineering with the 2000 mpv, it is a very difficult fix, and one that requires removal of the transaxle and exhaust manifold, as well as removal of the lower engine mounts. It will take a qualified Mazda mechanic 3.5 hours to do the fix - you can (at least) triple that amount of time as a DIY project (assuming you have the right tools).
