I bought a 2nd hand boat and I could use some help on wiring the batteries for a 12/24 volt trolling motor.
The boat is 16' Alum., has a 40 hp Yamaha on it, and the trolling motor is a Motor Guide 756 Brute (56 lb) and is 12/24 volt.
When I bought the boat the guy didn't know if the trolling motor even worked, said he didn't use it.
He was in the military and the boat sat up for the last 14 months untouched, both batteries (cranking & trolling) were dead of course. He replaced the cranking battery before I bought it.
I hooked the trolling motor up to the new cranking battery just to test it. It works, but only if the switch on the foot control is in the 24 volt setting. Doesn't work if it's in the 12 volt setting (Should it?).
Now I plan to get a new trolling battery to add to the boat. My question is:
1. Should I run the trolling motor off the 2 batteries (one being the cranking battery) to get the best out of the 24 volt trolling motor? And if so, how would I wire it for this set up?
Or,
2. Would I be better off not trolling with the cranking battery also, just use the trolling battery alone. And if so, should I be conceared about the TM only works in the 24 volt setting? Will that hurt the TM?
The TM seemed like it wasn't going at full power when I tested it on the cranking battery. Surely because I was only on 12 volts. How could I get it to work on the 12 volt setting if I decided to just use one battery to troll.
My fishing days are not long ones and don't happen often, so battery run down on the cranking battery from trolling should never be a problem.
The boat also had a dual (10) charger with it, so as long as I remember to plug it in both batteries would get charged.
Also, if I ran a 24 volt setup, would this effect the running lights on the boat, blow them? (I assume if wired correctly it wouldn't).
Thanks in advanced for any help, info, tips, links... If I left out and details that are needed just let me know.
