Sorry i did not see your message until tonight-- might work for you to send me some instructions- i am pretty handy with electrical tools and projects but AGM batteries are new to me. What type Gulfstar do you have- would love to see it -- mine is a gulfstar 51- basically a gulfstar 47 with a 4 foot factory extension - one of 4 made.

i am in waterford harbor -- are you available anytime this coming saturday?

I have a Gulfstar in Kemah at Watergate. I am also a qualified electrical tech. I will be in town in a couple of weeks if you want me to take a look and test them. I am always happy to meet and help a fellow Gulfstar owner. What marina are you in?
