I purchased a 1989 C&C
30' MKII earlier this year - has been running well but recently found the 14 year old 10 amp Guest battery charger
was dead and the 2 existing flooded 12v batteries would not hold a charge properly (used a Craftsman charger
to see if they would hold).
On the recommendation of a friend I have purchased a new 20 Amp Xantrex 3 stage Charger and am planning to purchase
2 new AMG batteries to replace the ones I currently have.
After some research
and reviewing several old posts I'm a bit concerned that I may have issues with my existing alternator
(am pretty certain it is the one attached to the original Universal M3-20A 3 cylinder engine).
Am I taking a risk with my current
setup adding AMG batteries? Can I get away with not replacing my alternator
Some additional information:
- Boat is at a marina hooked up to shore power
most of the time, fed by 30 amp 125 Volt AC plug
- Use auto helm
& speedometer but no fridge, windlass
or major power draws when under way.
- Usage is generally limited to day trips and occasionally anchoring
out for 1 or 2 nights, and generally only run lights and occasionally use electric
Any suggestions or comments would be greatly appreciated!
Thanks much in advance,
1989 30' C&C
