Check the accessory solenoid in the control box, you should have voltage on both big posts when the key is on.

Check the accessory solenoid in the control box, you should have voltage on both big posts when the key is on.yes when key is on and about 1.4 volts when the key is off.this is on the left hand side solenoid as veiwed from the operator position.the rh side has 12 on the top pole only whether on or off . thanks for the prompt reponse.

sounds like a breaker, check the four on the front side of the control box, if good check the cb breakers inside the remote box behind the key switch, 8 screws fasten this panel, or call wmz,  sorry,

With something jamming on the battery box im trying to think what that could have done, and all I come up with is maybe a pinched lead going through there?
But that should be easy to spot with a visual inspection?
The battery didnt get a big amount of pressue as cause internal damage?

cheers

Like drobertson mentioned, check the breakers inside the control box underneath the keyswitch. CB3 (the second breaker from the left) feeds 12V to both drum switches and the hydraulic solenoid.

Correct me if I a wrong But it sounds like you started the motor post crushing. This should all but rule out the battery but that leaves lots of little electrical things. First remove your breakers cover and check voltage pre and post reset, also look for signs of smoke or burn componets. It is hard to tell what may be bad IF the positive terminal cam incontact with the cover and you had a bad ground close to the battery and a good or better on in the control panel. Check the breakers and check for voltage in the control box. Do you have accuset?
