Thx Chris that's a good start.
Yup the converter is gone along with the wires(that I can see). The previous owner removed them all
I thought the speedo was 12 v too. Because the tach is 12v (from what I've seen online) and the odometer is not working aswell. Basically only the volt meter and the lil 24v bulbs work.
Do you know how many wires come from that converter and where I might find at least some part of it.

Thx
