[Rhodes22-list] Electrical Question

[Theodore Boender]

I agree with Stephen. If you put the switch in the both position, it should charge both. I don't think you'll need it if you have GB solar panels. The motor has to run a lot under load to charge the batteries. Good thing with our little outboards is that you can always pull start.
