I am using this forum as a last resort. I am having cronic problems with my charging
system and i am in the middle of the Pacific, in Micronesia. A year and a half ago I replaced the engine
of my boat with a Volvo
D2-55 which comes with a 115A alternator
. I also had work done on the electical system, which has a starter battery
, 4 x 100A house batteries and a zantrex pathmaker and isolator switches. Since then we have be on the move and have had consitant problems with the batteries and charging
systems. I have replaced the batteries twice as they have died - once in Tahiti
(with automotive batteries - the only ones i could get) and again in Fanning Island with Interstate SRM-24 (again the only batteries i could get). The new batteries seem fine for a while - say 2 months, but them seem to die and will not accept charge even after I equalize. The voltage goes up to 14.2 after about 15-20 mins of charging, and the amperage drops right down.
I have checked all connections ect, and I cannot find the souce of the problem, however I have a few theories:
1- The batteries are undercharging due to a voltage drop caused by the pathfinder?
2 - The alternator regulator
3 - The alternator is overcharging the batteries as it does not drop the voltage to below 14.2
Any comments regarding this or new theories. My next stop is Papau New Guinea and I will not beable to get batteries there, so i am thinking of getting new ones here. They have Excide Nautica batteries for sale
- the only ones close to a deep cycle. Again I would appreciate any comments regarding this.
