Good to see your getting back into it, can't wait to see it finished

Yeah me too 

Well , had a bit more of a fiddle last night after work and found I have continuity on the switch return wire on all 5 switches and back to MPU board connector . Checked display voltage at 175V DC .. dropped it down to 150 .

Will check switch diodes while waiting on a parts order from RTBB including some .100 connectors (I only have .156 on hand)

Must pull my finger out now the weather is warmer and get stuck into the cab repaint methinks .
