It might be easier to salvage a complete PS1 board from a junked diesel unit.

John, That unit was a modified PS-1 bottom board with 2 8 amp rectifiers sunk to the chassis frame as replacements for the 6 Amp Diode bank.

4 motors can over heat the bottom board. The diodes can desolder themselves, and traces can burn.

The DCRU slave route is the best way to go. Just a 4 wire connection. G
