Metro alternator belts are hard to get tight enough; they squeal like Ned Beatty. Is there black dust on the front of the alternator? If there is, you probably want to start with a new belt; that one is burnt and would need to be even tighter, then it will snap the next day.

Horn will not work 1992 geo metro

Easy problem.
1. Find the horn.
2. Disconnect the wire to the horn.
3. Apply voltage from the battery to the horn via a jumper cable.
4. No sound? Horn is bad, replace it.
5. Horn sounds? Horn relay is bad, find it and replace it. Could also be the horn switch in the steering wheel. With horn disconnected, push on steering wheel and listen for the relay to click. No click? then you have a bad steering wheel switch or no relay.

Or take the car into a reputable service shop. Taking your steering wheel apart is difficult, probably not something you want to do on your own.

My geo 1996 i just install new alternatorand the sistem is charging 11,7 any help thx

Disconnect negative battery terminal and test the battery by itself.

A health battery should read above 12.6V +


A discharge battery will give the alternator a heavier load until the battery is full charge.

A low / depleted battery has lower resistance,


If you has a charger then it the battery slow charge at 2A over-night.


Tighten alternator belt and test system voltage next morning.

Help my 91 geo metro keep killing my battery and when i turn on the blinker it sounds like its shorting out. i un plunged the battery from the alternator wile running and it continued to run so i dont...

A little more specifics please. Not a good idea to run alternator with cables disconnected. Why do you feel its shortin out? engine not running remove baterry positive post and check for a itty ***** spark when you touch cable clamp to its post. That will tell you if something is drawing power from your battery.Make sure your doors are closed and ignition is off. Good luck.

Battery light stays on.

If it was not integrated into the alternator, the voltage regulator may have failed.  I don't know where it is located in your car but if it is external, you may be able to find it by following the smallest gauge wire attached to the alternator backward. They are generally connected with 'quick-disconnect' crimped-on connectors.
