Not a big deal, I just reorganized my motors and voltage and will be operational next weekend.  The lakes are all shut down, the back country is totally off limits because we have a bunch of fires.  I had to quit working in my shop just now because the smoke is so bad.

The first relays burt up because I thought they were on the small side, but now that I have monster relays, I have discovered it is the motor.  I tested the armature windings against the good motor and found it is bad and in need of rewinding.  I found a place an hr away that does this.  But if they are too expensive, I will rewind it myself.
