James, you can also save a lot of power usage by converting to LED's. My light bars took 18 bulbs alone & I also have the stock turn lamps a 2 55w driving lamps. The extra alt. is a great thing to have. With mine, I will just disconnect the 3 yellow wires and if the add on alt gives up ghost, I'll nreconnect the yellow wires and be on my wat until I can get alt repaired. With the 1000 thro 1200 this is the only option if you want to run multiple lights. Good luck with your Baby, James:waving::waving::waving::waving::cooldevil::cooldevil::cooldevil::cooldevil::cooldevil::cooldevil:Thanks for the info westgl. Will that give me more power to run extra lights? I put light racks on back of my bike and two small driving lights on front but hooked them up to switchs so I can turn them on and off as I want.
