[QUOTE="69ST, post: 175520, member: 5"] Anything above 13-14 volts should be enough to charge the battery and keep it charged. 25VAC seems like it'd be enough. The key is maintaining 12VDC+, at the battery and [I]under load[/I]. Raw AC voltage varies wildly...falling-off at idle, then rising dramatically as rpm increases. My 12v engine makes 30VAC at an estimated 3500-4000rpm, with 50VAC seen at ~7000rpm and it's nothing special. Doesn't really matter if voltage falls below nominal battery voltage, at idle; that's the main reason for having a battery in the system. As long as it charges, once revved above idle, you're rolling. I'd check battery voltage daily, over a week or so. That'll give you a better indication of its condition. Another way would be applying a known load, like a bulb, then monitoring voltage over a set time. You want to rule-out the possibility of the battery taking only a surface charge...a condition that's confused many of us, at one time or another. [/QUOTE]
