Ok Nino the man has just left the building. Let me just say there is no way I could have done what he just did. I am forever in your debt.

Problems/Concerns found:

Power supply board was missing two diodes hence no 5v. This is being rectified.

Transformer still smells. Is this normal? Is there something that should be checked. It is reading a little high in it's voltage. Pumping through 250v. Reading some note that were made reading 29vac as opposed to 25.5vac.

Last issue solenoid is reading way too high 38v dc as opposed to 28v dc. Any suggestions?

Apart from that it all seemed to be ok, hopefully when I get the power supply board back we will get power to the displays.

Thanks again Nino.
