Re: Electrical Problem
Hi weephee, I see you're in Ottawa. Do you sail the Ottawa River? I used to live there, but got into sailing after I left.
Deep cycle batteries are not very good starter batteries. They're designed to sustain deep discharge, not to deliver big amps quickly, as is needed for starting an engine. They can do it, but a big drop in voltage during the start is not a surprising outcome.
I'd suggest buying a dedicated starter battery, and keep the deep cycle as the house battery.
Why go fast, when you can go slow.
