im new at this please cut me some slack. i hope somebody can help me out .what im trying to do is put a 12v battery on my trx250r quad, so i can run HIDs or LED lights on it , yes i know you can use a 9v battery to fire up then switch over to the stator power (A/C) but when the rpm drops to a idle there goes 400.00 in lights.so i think i want a rectifier reg. or how do i charge a battery with a A/C circ.i hope some one can help, thanks
