On this race tv cab ….

Will check fuse on this distribution board …

Then unplug all the power outputs
And meter across them out puts and see
What it is
All about 100v I think

The two small voltage converters
Are

1. 12v. (. I/o ?
2 .24v. ( ffb motor ? /. Sound amplifier ?

I think the Sanwa pfx is 240 or 100v ?

and the Lindbergh 240v

So could this cab be without 100v?

That is a 100V distribution board, the two yellow wires coming in are from the transformer and should be a 100V at around 6amps

24V for the Audio amp is from a separate PSU and the Lindbergh, JVS get the volts from the Lindy PSU.

Doesn't matter what way, but you should be reading around 100-110VAC from those two yellow wires, if not then trace to 240V going into the Transformer, very rare transformer goes bad TBH.

AC current flow changes direction 50 times a second (50hz in UK), so it doesn't matter which way round the probes are on the terminals.
