About the Hydraulic motor
 

Can anybody tell me what the Amperage draw of the hydraulic motor is?

I would like to install a 'safety fuse' between the battery and ground, in case anything contacts the battery positive post, to ground.
(A slim chance, but in accordance with "Goddard's Law of Possibilities" ['It happened, therefore it's possible.])'

I suppose that I would need possibly a 400 amp fuse, but just guessing.

I will put a amp meter on the pump mtr and let you know what it is pulling. My guess is something over 100 amps
