Where is the electronic ignition located? I think the part number is HE166-0785. What dose it in tale to replace? Thanks again..
The electronic ignition module is located behind the flywheel and mounted to the timing cover just under the crankshaft.
Troubleshooting ignition module.
Connect a Jumper lead directly from the positive battery terminal to the positive (+) coil terminal (smaller diameter of the two threaded posts) Crank engine over while watching for spark, If spark occurs, the problem is in the low oil pressure cut out switch (if equipped) or related wiring, the lubricating system (low oil pressure), or in the other circuitry bringing voltage to the coil. If no spark occurs, try the next step.
Connect positive side of voltmeter to negative (-) coil terminal (larger diameter of the two threaded posts) and negative side of voltmeter to engine ground. Turn key on and or leave the jumper connected from the + battery terminal to the + coil terminal and rotate flywheel slowly by hand while observing voltmeter. Voltage should switch between battery voltage and 1-1.5 for each revolution. If voltage does not switch properly, replace ignition module.
Never put B+ lead to the coil negative terminal. This will cause failure of the electronic ignition module!
If ignition module is being replaced, be sure to connect red lead from new ignition module to + terminal of ignition coil and black lead to - terminal of coil.
