when I first start it the switch works but then light starts blinking and kicks out of gear. never any pattern. first I just shut it off then restart and after a few times it would work. it must have fried the regulator cuz now it will boil the bat. after a few min. I cant see how the regulator is affecting the fwd. I think whatever the real problem is fried the reg. I did just put a spool locker in the front diff. but so did my friend in his 500 and his works fine. Would thoes speed sensors cause that if they were shorted out? Any other ideas?
