Hello, I have a Beta 20, WOC K 20524. It has the alternate 70 amp alternator.
I'm trying to figure out what the alternator output is at two different RPM' s. One just idling at anchor and the other underway at my normal cruising RPM of around 2700.
This is to estimate battery recharge times both at anchor and underway.
Is there a spec sheet that might show the curve or some other answer.
Thank you for providing your K number. According to our records this engine was originally configured with a 40 amp alternator. However in looking at the picture you provided it appears as though you have a 55 amp alternator? Can you please provide additional information or perhaps a more detailed picture of the current alternator? I have provided information below on the 55 amp Alternator. Also, we are not back in the office until January 4th so I have limited access to additional information until then.
