Here is an Alliance Rotor Control Box, model HD-73-1. 6 wire model. Lights up. Tested with volt meter across rear terminals, when Left/Right switch is engaged, shows around 29.5 volts AC across terminals. Have no way to test further and do not have the rotor. Should be working. Box is clean showing minimal cosmetic wear.
