Thie is a continuation of the discussion from the PTO thread.
My 1987 Model 212 (M00212X420473 with engine Kohler 12 hp -#1613207073) has the "engine dies when the PTO switch is thrown" flu! I started on the forum with the PTO thread as that is where things seemed to be pointing (with my luck it is always the most expensive part that needs to be replaced or repaired). However a LJDD mechanic gave me this tip: " if you unplug the PTO and it still dies then it ain't the PTO". So I started looking at the other possible causes. The seat switch, transmission safety switch, wiring harnes, PTO switch, etc. Last eve I replaced the Transmission switch, shifter quatrant plate (which activates that switch) and the PTO switch. That entire circuit was tested fro continuity and is ok. I put the tractor back together and still get have the engine die when the PTO switch is thrown and the PTO is unplugged. With the PTO plugged in the PTO strarted up but the volt gauge dropped into the negative area and the engine started the slow dying dance. At 12:30 am I was too tired to even react!
Do any of you have any suggestions or can give me the benifit of past experience? I just spent >$900. on this for a general tune up, oil change, tranny flush and new deck bearings. BTW: I had to put oil in the engine before I could mow the first time as is was 1/3 low (which was the same day this issue arose) and I put at least 18 oz of trans oil in last night (which I thought I should check while the rear deck was off. I was replacing the seal on the shift lever as it had been leaking out of the top where the lever enters the transmission anyway). Those examples of fine service from my Nearest JDD are why I am spending my spare time getting to know the works of the 212. My plan is to check out the voltage regulator, coil and the harness in the tower (since everything to the rear has checked out.). The ignition switch is on the list also. Any other suggestions???
Any help is appriciated!
