Hi all, I am new to this forum and have just purchased a Honda BF15, manual start outboard, my first motor with a charging circuit.
The above comment has confused me, as my motor has a 12v charging circuit option. I have spoken to my dealer and they have said that no battery needs to be connected to run the engine safely, it is an option, however if a battery is connected ,the manual states not to disconnect a fitted battery cable with the engine running. The Honda manual states that the battery is an optional extra not a required item.
So am I right in understanding, that if I wish to connect a battery for accessories such as lights fishfinder etc, I can charge the battery from the dc output on the motor. However if don't have a battery connected then no harm will come to my motor providing I don't have the cables connected ?
I ve also read that Honda use a unique regulator sensor that only switches on the 12v output from the motor when a slight load is detected ? So I guess with no cables connected the output would be inactive ?
