Fsuper duty dies
 

I just bought a 1989 f superduty with 460 and 5 spd manual. I havent got into it hardly as the batteris are dead. Managed to get it running once with a spare battery but when the tranny is in neutral and
I let out the clutch it died. Seemed odd to me but my battery didn't have enough snort to start it again. Thought I would throw it out here in case someone else has come across this. Any help would be appreciated,
