Ok, I sent my PGMIV off repair thinking that was the problem with my RC valves but unfortunately after having installed it today the RC valves still don't work.

The valve cables have been replaced, valves themselves pulled out and serviced, the servo works when tested seperately. Just wondered if there could be any reason why the system still doesn't function?

I sent the PGM off to 2Tracelab for repair but his testing equipment wasn't working at the time so I wonder if the repair job actually worked or if there is another issue here.

I'm probably going to buy a secondhand PGM unit & card from Jap Yahoo. Is all I need the unit & card or do I need to replace anything else?
