Voltage regulator questions - buy it or build it?
Perhaps you folks can help me with this; my voltage regulator is not working properly and is overcharging my batteries with the engine revved up over 2K rpm. At idle it is no problem- charges around 14.5 v or less, however with the engine running over idle it's more like 16. Obviously I don't want to cook the batteries, so for now I've installed a toggle switch between the regulator and the batts and don't charge them unless my motor is at idle (not often). My battery bank is as follows - two huge deepcycle batts wired together as a house bank, and a separate starting battery. I'm in a marina and on a charger most of the time so this isn't an issue for day trips, but a problem for those longer journeys the boat is hoping to take soon.
So - if you needed a new regulator, would you buy one or build one? Anyone have any good or bad experiences with this? Ideally I think I'd like to have as much charging control as possible - I don't have a genset and will have to rely on the engine for power if those longer distance dreams come true.
Thanks for your help!
