Thanks for the reply. I will stop operating the boat until I get it fixed. I expect to have the boat for a while and I agree with updating with a new unit. If an updated regulator doesn't fix the issue, I will have the alternator checked.

Any recommendations for a new pair of new alternator regulators? Is the Balmar MC-618 with the Balmar SG200 with smart link a good choice? Or are there better options. I would like to fix it once and be good for years.

thanks. Rich

Ok, after more thought, I am going to research going to regulated alternator. I will be hooked up to the dock often, and the batteries should be topped off most of the time. I'll go by the boat in the morning and get the part numbers on the current regulators and call around to get advice / options.

Thanks hiccup for the informative post.
