Trans 2 help

I just picked up a old 48V Trans 2. It runs ok but nothing works on the column dash except the battery charge indicator. No lights, blinkers, etc. I suspect the dc converter died? I’m not sure, I’m new to these. Where can I find a wiring diagram and service manual? That would help tremendously.

I found the wiring diagram and it is the dc converter. I’m betting that its obsolete by now for the Trans 2, it is the exposed circuit board.
