Older Balmar 90-100 alternator rebuild

[Jammer]

My boat has an older Balmar alternator, model 90-100. It is the single output version. These were, apparently, built by Lestek, and were discontinued around 20 years ago.


The alternator appears to have failed after the engine was started on haulout day with the battery selector switch in the "off" position. I suspect diodes.


The diodes in these are a press-fit type, like the ones in this link:

I do have the diodes in my spares but am wondering about the difficulty of installation, specifically whether they can be pressed in place with ordinary hand tools. My boat is far away and I only have one additional visit planned before we recommence our delivery, so I would like to be prepared.

Any automotive alternator shop can rebuild a Balmar. I’ve never paid more than $75.. I must have done it about 15 times. So why am I still using a Balmar alternator?
