I dropped my motor and smashed the relay casing but the works seems intact but some parts bent. I can put the box together but I need to reposition some of the relay parts. I need to repair this one or buy a new one. I motor is fine and I cannot spend $300.;00 or $400.00 on a new one.
Is there a way you can show or describe the configuration of the relay itself or tell me where I can buy a new or rebuild one?

Thanks mch, I really need help on this.

Sincerely,
