Electrical failure

[Yves]

Hello
I own a 2019 Zero FX with low mileage. The engine and dashboard are functioning correctly, but the lights and horn are not working. I’ve already checked the fuses, and they appear to be fine. What could be causing this issue?”
Can somebody help me out?

I have what appears to be exactly the same issue on my 2017 FX/S.
It's an intermittent problem - sometimes the lights work, sometimes they don't.

In my case the problem was situated at the fuse of the 12V transmitter. As I understand : The main battery is 60V and a transformer is needed for the 12V components. It has a fuse that is not in the same box of the other fuses. The fuse was ok, but the cable was disconnected.

I recently got the service manual. It says the low voltage fuses are located
in front of the front power pack, on the right side of the frame. That seems like what I saw. It also mentions a low power fuse located on the power pack, controlling the power pack, lower down on the left. That doesn't seem like it would affect the lights. Where exactly was the fuse that you found ? Since the battery is DC, it can't have a transformer, it has a DC-DC converter.
As I have an intermittent fault, it can't be a fuse, but it could be a loose connector likethe cable you found.

I went to my dealer to solve the problem. As I understand it, there is a converter with a fuse. You have to take out the battery to have acces. There was a loose connector on the converter, I think between battery and converter.

Where is the fuse for the converter?
And Where was the loose connector for that converter?
And… a lil help with - ACCY 12V 10A (2nd pic)

From wired wits end…
