Yes, If you have to, on the left alternator of a 1008 or 1009 CUCV, you can
use a "grounded" alt on the LEFT SIDE ONLY since it is grounded. YOU CANNOT
DO THIS ON THE RIGHT SIDE AS IT HAS TO BE ISOLATED because they are in
series and the ground side of this alt goes to the POS of the left alt. You
can buy parts for these alts from NAPA or any other good auto supply. Parts
are cheap for these and the most common problems found in these units is
worn out slip ring brushes and bad internal regulator packs. Bearings
should be replaced and are pressed in the casings. Julian Burke
