Toro groundsmaster 455-D - Injection Pump (ETR) Solenoid

Battery
Use a hydrometer to test the battery. Charge the battery
if necessary (see Battery Service).
Electrolyte specific gravity
Fully charged: 1.250 - 1.280
Discharged
: less than 1.240

Injection Pump (ETR) Solenoid
The Groundsmaster
®
455-D has an energize-to-run
(ETR) fuel stop solenoid. The solenoid will stop injector
pump fuel delivery with any electrical failure in the RUN
circuit.
1. Disconnect the wire from the solenoid.
2. Remove the solenoid from the injector pump.
3. Connect a 12 volt battery so that a wire from positive
(+) batte
ry terminal is connected to switch terminal.
Touch a wire from the negative (–) battery terminal to
solenoid body. The plunger should retract.
NOTE: You can also test operation without removing the
s
olenoid from the injector pump. Listen for an audible
“click” as the solenoid extends and retracts while doing
step 3 of the above procedure. This will not show if the
solenoid is fully extending and retracting.
