engine dying due to electric fan

Have you tried to see if it stalls with either no fan belt at all, and/or with the field wire disconnected on the alternator, when the fan kicks in ?
haven't been able to do that trapster, have found some wiring problems in the bulkhead that need addressed first. have been reading a lot of other threads and trying to figure out how to test the circuits and replace the bad. don't know squat about electrical, so it's time I learned. thanks again for your help, much appreciated. any help with wiring/checks would be welcomed, and I'll keep searching/reading/learning, thanks again to all
