I have an 2012 electric Precedent that I am converting to lithium. I bought a new 48-12v converter for the lights but I’m having trouble connecting the wiring. The converter output is connected to the blue wire that was previously connected to the 16v tap off the old batteries.
In the picture above I’m getting 12v from yellow to black on the back of the light switch, with or without the key switch on. But neither the front or rear lights turn on.
Any ideas?
