Subject: Alternator

Sending this to both list because many people have loop frames and tonti
frames.
the ? is has anyone tried to put an automotive alternator on to a tonti
frame if so which one did you use .
my 93 cal111 has a hack and I pull a camper with it and have had
problems keeping the battery charged the up grade from mg does not
improve it enough to pay for the cost.Any ideas
