Hi
after some advice. I took on a project of repairing a 2018 zero fx that had the wiring loom cut in half. Ive swapped out the loom for one from a 2018 fx. the motor works fine but i cant get the lights(front headlights, front indicator, back indicator and tail light) or the dash backlight to come on.

Reading previous forum post point to the 12v dc convertor goin faulty or mbb. I have changed both parts with one from a 2019 fx and the lights still dont work. i have double checked the connectors and nothing is loose or unplugged so im sat here scratching my head on what it could be

so far i have tried the following
- all fuses checked
-internal bussman style fuses checked.
-12v dc board changed
-mbb changed
- if i use a power probe on the front fuse box and give 12v to fuse 5 and 6 which are for the dash and the lights i see that the dash and lights work fine so to me the circuit seems to be fine?

any ideas or suggestions on where to go from here?

thanks

Light bulbs burned out?
If it's led, then there might be a driver issue.
When that harness got cut it could have spiked something and goofed them up.

lights all work fine when i manually give 12v using a power probe to the fuse box which is what is confusing me

Not much left then, can you measure the contacts of the DC/DC? Input voltage, enable voltage, output voltage.

Did you have a look at the circuit diagram?
