tohatsu 6hp charging output amp numbers

real time numbers on amps the little motor is putting out. At idle it is putting out 12.5 volt and 13.5 at 1300rpm, but the amps don't really kick in till 2000 rpm. it will run one fish finder two is a bit much but will slow the drain in battery at least. I troll for hours so it works for me. will see about getting rid of the cig lighter as vibration keeps popping it out.
