Engineer-Joe & PCRR/Dave,
Joe the # on the bulb is 757.
Concerning my block wiring. I daisy chained the individual block. To get a 18v reading on the entire layout. If the layout was a circle the block wire started at 6 and daisy chain from there to 9-12-3 on the clock.
So the center rail should be cut at 9-12-3? And if 28v or a 18v bulb should be placed at the end of the switch. As in Dave's picture.
