I want to use the KYMCO scooter to charge an external scooter battery. With the external battery, I could use an inverter to power small 110 VAC devices in an emergency. My thought was to turn off the headlight during the charging operation to lighten the load on the alternator. (There is no ON/OFF switch for the headlamp.) Once removed, I expected either the 10 A or 15 A to kill the headlight or all of the lights while the remaining fuse would run the engine. Unfortunately, what I found was that removal of the 10 A fuse killed everything. Then, to my astonishment, I found out that removal of only the 15 A fuse also killed everything except, I believe, the fuel pump. My plan is ruined!
I could put a kill switch in the glove compartment or under the seat, but that involves the disassembly of plexiglass panels and finding the appropriate wire in a wiring harness. I would be satisfied with turning off only the front headlight and letting the other lights function.
In my old age, I seem to have forgotten the days when I traced electrons through a heavy fixed military radar set in the Air Force.
During the charge operation with a fully charged scooter battery and a discharged external battery, I plan to attach the batteries together without running the scooter. After waiting some time for the two batteries to equalize, I would start the scooter and allow both batteries to be recharged.
Does anyone know why removing either of the two fuses, essentially kills all electrical functions? And, does anyone have a suggestion on how they would proceed with this project? Thanks.
