I recently upgraded by main power and starter batteries
to Lifeline AGM's. I have the following:
2 GPL-4DL 210 Amp Hour batteries
1 GPL-1400T Starter
Currently I have a Balmar
90 series 100 AMP alternator
with an older regulator
that is not setup to handle the charging
needs of AGM's. The Balmar
is connected via a 3/8inch belt.
This is all connected to a Westerbeke
38b diesel engine
with a single
vee pulley system.
The issue I am having on a regular basis is the belt slipping. I have to keep tightening it, but even then it will start slipping when any real load is put on the Alternator
, especially if I use the windlass!
The 3/8 belt is under powered for the Alternator running at 100amps which is causing the slippage.
I am looking to upgrade the Alternator/regulator to a newer model to accommodate the new loads my batteries can handle, but in doing so I would have to upgrade the pulleys as well.
I am getting overwhelmed on what to do. Would it be better to get the Altmount system for the pulleys to convert them into serpentine to go with the new alternator or do I get a smaller alternator to fit the size of the belt I currently have and then add another alternator to make it a dual belt systems... That second option seems more expensive and more electrical work
