Car Alternator

We need to test with a voltmeter.
Unfortunately we don't have one. We need to buy one.
The alternator is not powering the car. When we remove battery terminals when car is started car dies.
Forgive my English we standing in hot sun.

With most modern vehicles removing the battery would probably make it die, at the same time you may be killing your new alternator and potentially other electronics in the vehicle.

I got a feeling this is going to be a story of diy gone horribly wrong

That's a very good call, the original alternator may even be perfectly fine if that's the case.

Now you see.
I said it happened right after charging my cellphone.
No one said bad earth connection.

Everyone made me buy a new alternator.

Even my mechanic.

And that's why you either pay R1000 for a auto electrician or fix it yourself. DIY fix would probably be less than R200

Ain't got nothing to do with you charging your phone
 
This is going from bad to worse. Just take the car into a auto electrician. You are going to end up really screwing something up.

No idea, ask Google. Did you charge the battery? That could also cause warning light to come on ( if battery voltage is too low)

That's why I recommended getting a battery charger.

I'd take the car for a 20min drive and see if the light doesn't go off once the battery gets some charge, before doing that check the earth cables.

Find the manual on the Internet and get the earth location.

They are quite easy to find though, big heavy black or uncovered electric cable, one going from the battery to body and one or 2 from the body to engine/gearbox. Worth also checking the positive alternator to battery cable connection.

Could it be a blown fuse?

Probably least of his problems at this point, we can only hope the op hasn't burnt his car to the ground by now.

Wonder if he has learnt the "how to weld things using just a car battery" lesson yet. :D

We think this is the problem.
If I disconnect this wire from the alternator and check the voltage on this line, it should be the same as the voltage across the battery?

This way i can tell if the cable line is working correctly?
 
There is something we are confused about.
The Bosch alternator had one connection point, while the new one has three.

Why does it have three?

I checked all the fuses none are blown.
I have a problem with the fuses though, the manual shows a completely different configuration of fuses compared to the actual layout in the car instrument panel. The fuses in the engine compartment are same configuration as in the manual.

Why are they not the same for the instruments?
How then do I tell which is which in the instrument panel?
