why are you pulling off the negative wire?...it needs to be attached in order to complete the circuit....

while the car is on, the battery terminals can be taken off and the car will still run/idle
iono man, sound like a loose alternator wire

once the car is on, the alternator can power the car. the battery is only needed for startup and when the alternator slows down spinning

i just put it in tho made sure everything was tight.is there a relay 4 the alternator that maybe went bad?

alternators at idle only increase the voltage from 12 to like 14.2...wouldn't everything run real badly on 2-3volts?

ive driven without my battery completely hooked up. the volt meter said 14ish until i took my foot off the gas, then it dropped for half a second to like .3 (lol) then settled back at 14.
ur car shuts off for 1/4 of a second then turns back on

oooh...i see now...i always thought the alternator just added voltage to the system by the 2-3 volts...instead of outputting ~14volts needed to actively charge the battery...that makes sense now...
back on topic tho...double check all your other positive/negative wires...not just the ones on the battery but the ones coming off your fuse box under the hood and other major ground wires...
