its way out. Is there a modern equivalent? The one that failed is the one that cuts power when the brake is applied -- I have it jury-rigged in a bad way. The one that is failing I'm not quite sure yet, but to be on the safe side, I would just replace all of them.

Feel free to correct me if I'm wrong. I'm not sure how much "coil" current these would draw so I'm not sure what resistor to get to drop it closer to 24V.
You might want to wait for the more experienced people here to look over this, before considering this an option.
