Sounds simple, but doing an alternator and belt change was a major project! On this CAT 3126 there are steel covers over the alternator, belt, and flywheel. So in very tight quarters, removing the covers to simply get access to the components to be changed was a challenge. Next door neighbor and Dock-mate “Bobby” of 5K was a great help! Thanks Bobby!

Possibly the original alternator from 20 years ago?!?!

The plastic/rubber “boot” over the “+” terminal was very brittle… certainly seemed like it was 20 years old.

When you buy a 20 year old boat, you’ve gotta be ready for stuff like this!
