Hello

I have my Fedal vmc 15 xt. from 1995 with an 88hs control
I recently bought and installed my 4th axis vh65 and it works like a charm.
the only thing is that i cant get the airbrake to work.
when I type m60 there is no voltage at what i think are the good leads for the air solenenoid

i have checked al the fuses and solid-state relays they all seem to be fine.

if someone knows where I could start to look for this problem, I would be thankful.

with kind regards Simon
