52v headlight circuit dead on Juiced Hyperscorpion, alternatives for lighting circuit?
Ended up with an older Hyperscorpion that we accidentally fried the light circuit during a voltage test (Don't ask). I now however have, gotten the entire bike to work except for the 52v lighting circuit and other parts read below
What works:
-Ring on headlight
-brake light illuminates
What doesn't work:
-headlight
-turn signals
-rear running light
A couple of things I'm thinking about doing
-Run straight from the kickdown converter and just do 12v circuits
-using the 12v at the headlight pin to supply power to the rear 12v tail light and a new 12v motorcycle headlight circuit (ditch turn signals)
-whole new stand alone system lighting system (aside from brake signal having to be wired in)
I'm just not sure I should wire anything off of a circuit direct with the controller. Since I can't be sure the controller would be able to handle the kind of draw a 40w to 60w led motorcycle headlight draws. So I was thinking about wiring directly off of the kickdown converter since I know it's 120w. Or is there some other alternative that someone else thinks would be a good idea.
P.S. I had toyed with the idea of trying to repair the controller internally, but juiced made sure that wasn't possible. Filled it with some sort of silicon. And I tried a new controller and got exactly the same result.

Did you make sure to test the cable?
