Ignition System Operation

Testing the Ignition System
Greensmaster ® Flex 1018/1021
20247SL Rev A
The engine on the Greensmaster has a magneto ignition system consists of an
ignition coil, a spark plug and permanent flywheel magnets. A flywheel key
maintains proper ignition timing.
Note: Do not remove the spark plug from the engine when testing the ignition
system. The spark plug is necessary to maintain normal starting speeds.
1. With the engine not running, remove the spark plug wire from the spark plug
and connect it to the spark tester.
2. Connect the spring clip of the tester to a good, unpainted ground on the
engine block.
3. Ensure that the ON/OFF switch is in the ON position. Also, ensure that the
traction control is in the NEUTRAL position.
4. Pull the engine starter rope and observe the spark tester. Visible and audible
sparks should be produced if the ignition system is operating properly.
Note: If a sheared flywheel key exists, the spark tester may indicate an
operating ignition system but ignition timing will be incorrect.
5. If visible and audible sparks are not produced, a problem exists either
with engine ignition components or with machine components. To identify
whether the problem exists with the engine or the machine, disconnect
the wire harness connector (violet wire) from the engine primary wire and
repeat step 4 above.
A. If visible and audible sparks are not produced with the engine primary
wire disconnected, the engine ignition system is not operating properly.
Refer to the Honda Service Manual for engine information.
B. If visible and audible sparks are produced with the engine primary
wire disconnected, machine components (e.g. on/off switch, interlock
module, machine wire harness) are damaged or faulty. Refer to machine
component testing information in this section.
