i am connecting an alternator to my truck for the sole purpose of charging a battery to boost other vehicles with but i cant figure out how to deliver the chsrge. is the alternator grounded to the battery and the large wire from the back of the alternator the lead that goes to the pos on the battery or am i totally out to lunch? Is the 2 prong plug just for guages or is it for the lighter too?

GM?
Ford?
Dodge?
Toyota?
Nissan?
What year?
ADDED:
Generaly, the alternator uses the mounting surface as ground, and the large gage connection is your charge wire.
The two prong plug is one wire is ignition supply to excite the alternator, on the other wire is for gage or idiot light.
If you don't have it hooked up right, it will not charge, or will draw down the battery while it's turned off.
What Model?

I am assuming you are using a Delco Remy alternator (GM), which has an internal voltage regulator. In that case, the large wire at the back of the alternator goes to the battery POSITIVE. The alternator should already be grounded -- when you hook it up to the engine, the brackets that hold the alternator to the car or truck frame should provide an automatic ground.
As far as the two alternator terminals, if you look at it from the rear, the left (#1) goes to the idiot light or it can be used to run an electric choke on a carburetor. The right (#2) terminal needs to be hooked back into the large wire that goes to the battery. This provides the sensing for how much voltage the alternator puts out. If you don't hook that up, it won't charge.

yup the large lead should go to the battery pos, you have to remember this is an alternator, not a generator. A small amount of electricity need to be supply to the electromagnetic fields in order for it to produce more voltage. Generators have permanent magnets. you should have a stator connection on an alternator that also needs to be connected , the also alternating current needs to be rectified into Direct Current if a diode is bad it will not charge either

This I can tell you. I have no idea of the color coding on your altenator, but if you attach it incorrectly and re-attach the battery, you can fry that altenator fer good chum.
