i have a nice and clean mc30 that the customer does not want to get rid of. the battery is charged. the accelerator sensor was replaced (in the little box) the fuse out back was not allowing voltage thru. changed that. all the contacts are closing properly; I hear them clicking. I was about to pull the battery and check the contacts on the motor. I cannot find any schematic or troubleshooting info on this thing. any help would be helpful.
