I’ve just pulled the trigger on a large case 200 amp alternator from Compass Marine for my ‘74 32 with a single Lehman. I got what I think was a great buy on a what I will use as second alternator to charge my future six T-105 AGM house bank. I plan to keep the original 55 amp alt. to charge an isolated start battery and set up the second alt. as a separate charging system with a three stage external regulator and monitor.
Now comes the fun part- I’ll need to fabricate a mount. I’m thinking I’ll leave the original in it’s place and mount the second alt. low on the starboard side of the engine. The engine already has a 3 v-belt pulley on the crank from a compressor that the original owner had installed at the factory (the compressor is gone). So I’ll use that. I’ll have the alt. built with a two belt pulley.
Does anyone have a picture of a similar setup? I’m a pretty good fabricater so the installation doesn’t scare me. Just looking for ideas for the mount.
