On the way home to NC from Tn, the alternator on our 1986 Coachman motorhome, 2.4L, EFC, auto gave out on us. Having tried doing some research on which alternator to order for replacement but none on the auto parts stores has any info. The only help was Advance states the 1986 Toyota pickup only calls for one 70 amp alternator. Any way to tell which alternator I need short of pulling the old one off which I don't want to do until I have the replacement in hand. Also the brake light came on when the charge light came on???? From reading on this forum, this is a difficult job. The alternator is in a tight place to get out once it is removed. Any thoughts.
