my car has ghosts....

[kailo]

fun background story -

had a old tiredish battery after car wouldn't start replaced it. And after finally making it home checked the voltage seemed alternator was not working. Seeming as i had a spare "unknown" condition one i figured i'd
give it a shot. the spare was slighty differnt with its connections. Car fired up fine alternator seemed to be boosting that volts...

now for the fun part -

while giving it a little revs as i was testing there was a bit of smoke and now the car runs after it is turned off at the key. infact unplug the battery it still runs the only way it seems you can turn it off is to stall it.

smoke kinda looked like it was from the direction of the alternator/ front of motor area so would i be right in assuming a bad one can make this happen? or is it likely something else fried? i figure it is cooked now but was it likely wrong wiring? was pretty weird
