Charging Question
Do any of you charge the cranking battery while it is still hooked up to the engine and all the goodies. The reason for the question, I charged a battery on a boat I use to own and it burnt up a CD module.
It is not enough that a man should toil and provide,but that he be granted the pleasure of fishing with a friend.

Same here. But you're not supposed to have anything on when you charge--I disconnect the trolling motor and throw the master switch before plugging in.

My cranking battery is on the charger anytime the boat isn't in the water or on the road. 12 years and counting with no issues. The outboard's alternator puts out the same voltage and more current than the charger, so a properly functioning charger won't hurt the outboard. It's possible a poorly designed or defective charger could cause problems, but the battery is a really good protection circuit to prevent excessive voltage.
