Problem: will not crank on its own, will crank with jump box—but still not fire
Recent things I did prior to this issue: cleaned fuel filter, replaced battery cables, replaced cable from ignition to starter
I have my test light out and am probing around.
There is no power at ignition/magneto wire or the ignition/starter wire
There is power everywhere else

Need some help. My 800 Special has an electric PTO. It is not working. Checked Ohms - nothing. My questions are 1) how does the PTO come off and 2) can they be rebuilt? I took the bolt out that I thought holds it on but no luck. Must be something more?

hello all I'm a new owner of a 312-8 tractor, have starting problems, came across a very small, what I believe is a relay between the battery and the dash,its about 2/3rd size of a cube of sugar silver on the outside blue on top with a hole bout the size of a pea, theres 6 pins with wires connected to it on the bottom do not know what this is any thoughts? I cannot determine the exact year of this machine for there is no tag anywhere only tag on engine kohler magnum md #m12s ser# 170370459 spec# 471527 I figure its mid to late 80s to early 90s. of all the wiring diagrams ive looked at it does not show any thing like what I just described also can that little circuit board be removed that's like a test point for idiot lights? any help would be appreciated jeff
