I have a 1991, 35 hp Force outboard. I have a two-battery bank connected with the recommend battery integrator (Newmar). When the integrator kicks charging power over to the auxiliary battery, it trips the fuse that is at the conection point of my wiring harness to all of my auxiliary devices. I can sit in the water for hours with no problem using lights, stereo, etc off of my auxiliary battery. But, as soon as I turn the engine over and start cruising, the auxiliary battery calls for power, switches the integrator and trips the fuse. I can reset the fuse, but it repeats. A local retailer told me to up-size the fuse on the auxiliary wiring harness, but to make sure that it is rated higher than the amp output of the motor. Is that a good idea? Why would a manufacturer of a universal wiring harness not rate it with high enough protection for a small outboard motor? Do I need a bigger fuse or is there an underlying problem that I haven't figured out yet?
