Newbie Question

[wildtalk]

I did install a battery guage to keep an eye on the main battery ,, and also a 2nd battery for bilge and pump for bait well.. The 2nd battery I have a 5w solar pannel attached... When its in dry dock its on a rack at my yacht club. may put another 5w solor on main battery while its in the rack,, but dont have a lot of faith in them,

Yes, your engine DOES charge your cranking battery while it's running...all the suggestions here will help keep it charged while not running...another consideration is an onboard battery charger...if you have a 2nd battery for bilge-pump, etc, you might want to consider an onboard charger as it is NOT being charged by your motor...I had 2 Guest chargers on my boat and LOVED 'em/11...plug 'em in and FORGET about them short term or long term...your batteries will be hot to go when you're ready!!...
