Hi,
I own one off the elder generation of Arien Tractors with a 16hp Kohler Engine.
We have a problem starting her, no spark.
How do you bypass all the "cut-offs" to check that the spark is Ok ..
In one of the manuals I have there was a wiring diagram to show this ..but .. I cannot find it now ..!!
Can anyone help ..?
Thanks

Most tractors require stepping on the clutch/brake pedal (set the parking brake), transmission in neutral, blade engagement off and you sitting in the seat (sometimes overridden by parking brake set). Turn key to start position and you should have spark. If you don't have spark then you need to physically check each safety switch with an ohm meter and check your coil ground wire to make sure the insulation is not rubbed through. You could also have a bad ignition coil.
 
Hi,
Thanks for the advice ..
but ..
There is a way of by-passing all these safety switches by clipping a wire from one terminal to another ..
I have seen it somewhere.. but I cannot find the diagram ..
This is what I need .. the diagram for doing this ..

Please do not bypass any safety switches on your mower as they are there for your safety and the safety of others. You need to find the problem and fix it accordingly and I have given you a starting point.
 
Hello,
Thank you for the advice, but as this being carried out by a proffesional engineeer and not a "pleb" and as it is to check and solve a spark problem, I have to bypass the safety system.
It will not be used to run the tractor, and there is no mower deck attached ..

The safety switches either ground the coil or prevent voltage from reaching the solenoid so clipping a wire in the system will prevent the engine from starting. Simply remove the kill wire from the coil(s) and crank the engine to check for spark. If you now have spark the coils are good and you work back from that point checking all components in the system using a multimeter.
