I bought a fishing boat last year with an f25mlh65w outboard. The boat had an onboard charger which recently went kaput. I took the charger out, and wired the output from the outboard to the common post on the 1/2/both switch, after having heard that it was bad to not have the charging system wired to a battery.
My problem is that the voltage being delivered to the batteries, (which test at 12.6v isolated) through the rectifier is too high. (15.5v @ idle and 15.75v @half throttle)
I’ve also been told elsewhere that the 2005 f25mlh 65w did not come with a rectifier... but it did come with the leads from the stator to connect one if you wanted to charge a house battery.
I’d like to know if the rectifier(non OEM) that has been put in by the previous owner, can simply be removed, and the two leads from the lightning coil be capped and tucked away?.. or would they have to be dealt with in some other way?
I’d also welcome any thoughts about whether the 15-16v while the engine is runnning is a major problem... and if so, any suggestions about ways to get that down.
Thanks
