Andrew Z said: (quoted from post at 15:23:55 06/21/09) im working on geting my super md's generator wired up i have followed the manual for the tractor and used bob m's diagrams to check over everything. however i seem to be having problems with it charging. when the engine is running i get 13volts at about 700 rpms yet when i increase the rpms it drops way off to 12 or less. finally when i stop to tractor it shows a strong discharge out.

Andrew
