Hi guys!
It´s me again with another problem... I want to install some HID´s on my scooter but the standard wiring is connected to the alternator thus it supplies AC voltage which will not work with an HID ballast. I tried adding a rectifier but it didn´t work because the voltage is not steady - I get about 9VAC when my engine is running on idle and the HID bulb is flickering and sometimes even not working on idle.
So i want to cut the yellow wire going from the alternator to the light switch, and connecting the black wire to the yellow one going from the battery to the ignition switch. So now when i turn my key, i get 12VDC from my battery to my lights switch and then to my bulb connector. I know that i need a new fuse (factory one is 5A as you can see on the pic) but how can i know if the wiring isn´t going to melt? The ballast will draw about 8-15 Amps on startup for about 10 to 20 seconds, depending on what HID kit i buy. After that it will draw about 3 to 5 amps.
So what wire gauge do i need and how do i know if my current wiring is enough? Everything on my bike that needs switched dc power draws power from that ignition switch and that black wire.
Complete wiring diagram will be below in second post
Thanks,
