bench testing my 350v8, how do i wire it?

ive got my rebuilt engine with a holly carb out of 71 chevy truck and was wondering what is the best way to wire it up so my battery will charge? I've got three hook up points on my alternator(plug in w/two wires,and a separate wire that i think goes to battery) ive got no ignition, would a toggel switch work? ive got my starter, and a dui distributor with one wire hook up.i would like to use this to charge batteries and jump start cars at home.

where dose the plug in wires(2) from alternator go?
where dose the other wire from alternator go?
where dose the one wire from distributor go?
what hooks up to starter?

thankyou for reading and any help would be appreciated.

woring

See if I can get you started here. BAttery positvie goes to the large stud on the soleniod of the starter, # 10 gauge wire goes from there up to the alt battery terminal, run a 16 gauge wire to a switch( single pole single throw). Connect one end of the switch to the B terminal on the distributor and the other end to battery +. Turning it off will kill the ignition when the engine is running. Need a push button switch or something similar to hook to the solenoid terminal on the starter solenoid and the other end of this switch to battery +. Pushing the button will engage the starter. Battery negative will connect to the block anywhere you can get a good ground.
CAn't recall what to do with terminals 1 and 2 on the alt. Seems like we used to conect them together and then tie them into the battery terminal on the alt. Maybe someone else will jump in here that can recall.

thank you for your help im charging my battery now.i did get it to turn and it almost caught.i hooked the one line from alternator to positive and the other to starter dose that sound right? or do i not need the two alternator wires from clip hooked up.my main use for now will be to charge batteries to get other engines ruining.so if i not need the wires hooked up to charge I'll disconnect the clip.thanks again

You will need a battery charger to properly charge the battery.
An engine driven alternator is designed to maintain a battery during vehicle operation.
An inexpensive battery charger is adequate.

Vicrod is correct on the charging thing. A alternator is a poor choice for charging batteries. It will keep a charged battery at a correct level but it was never designed to charge a dead battery to the correct specific level.

That alternator should be putting out 14 to 15 volts if it is charging correctly and has been excited. That is the purpose of the two wires on the terminals 1 and 2. I believe 1 goes over to battery and 2 goes thru a resistor or a bulb (as in idiot light on the dash) and then to battery but I am not sure on that one precisely.
