A question for the more electrical-minded out there.

My dad's on-board charger died on him - there is a possibility it remained plugged in when he pulled the boat out of the garage this spring, but we get no charging lights when we plug it in now.

I did a search to try and find the same exact model so we don't have to drill any new holes.  He has a Guest Charge PRO 2623 3-bank charger.  Couldn't find any of those, but I did find a 2631 model.

The only difference I can see between the two is the 2623 is 10-5-10 amps, and the 2631 is 10-10-10 amps.

He has an 18' Lund Tyee, 130 HP Honda 4-stroke, with a 24V trolling system using 2 batteries, plus his starter battery.

Does the extra amperage going to the starter battery make any difference?

Thanks.
