Hi all,
Our 2003 Jimny is up and running again after our m15a engine swap. Runs like a dream
However the original alternator has packed it in thanks to a bit of water

Just after some advice on a good way forward from here...from what I've read the stock alternator gives out 75amps which isn't too bad. We will be looking to install a dual battery system at some point down the track, likely to run a few lights and a winch. Should we be looking to upgrade to a Falcon alternator, or would a stock one be sufficient?
Also can you swap a different Suzuki alternator (from an m16 or m18?) to give a bit more output?
Cheers
