Hey Kailas, Its not dat I did first or u did first since none of us did it first :-))
Since its the same old tech. I know wat all u did is safe but a single 5ah battery wld've costed u just few Rs more. Dats wat I like to say & if u go for a regular battery adding distill water wld've been reduced to just 1 battery ;-)) Hv u checked the Uni HL function. It works in AC & when the pass switch is pressed the DC is injected along with AC. If u cum across the circuit details plz let me know. regards, james.r On 27/02/2008, Kailas Shastry R <[EMAIL PROTECTED]> wrote: > > James, > > I remember a headlight mod thread where I had responded to some of your > queries.
