Location: Perryville, MO | Electricity makes no sense to me at all. I actually know Greek so saying it's "all Greek to me" wouldn't work. But you get the point.
My buddy, who's an electrician, has set up my electical system. My trolling motor is 24v. So I've got two batteries hooked up in series. So far I understand. (I read atomic physics but can't understand the great mystery of electricity...so ridiculous!)This is what confuses me. I'm still using one of those batteries as my cranking battery and for my electronics (of course 12v). Ok, the how this works thing, I'll just try to get past. My question is: Is there any problem with this or is the reason for running three batteries (as most guys do) just the security of always having enough cranking power for the boat motor?
He talked me into this last year. I've never had any problems at all. Never a problem with juice to turn the motor. It starts quickly every time I turn the key (knock on wood).The only thing that got me thinking about it again was the mishap I had hooking up my batteries for the first time this weekend. The ground from the motor to the boat was apparently corroded and the next thing I know there's smoke everywhere as the lower unit ground wire burnt off its casing. (No real damage and I easily ran a new ground wire...after my boat mechanic got a chuckle of me calling him all frustrated...and him telling me to go run the boat and not worry about it.)
Anyway...what do you think about just running the two batteries this way instead of three?
