Fuel Sender - Toro Reelmaster 5010- H Service Manual

Fuel Sender

The fuel sender is a variable resistance device that al-
lows the InfoCenter display to show level of the fuel tank.
The fuel sender is located in the fuel tank (Fig. 78).
Testing
1. Park the machine on a level surface, engage the
parking brake, lower the cutting units and stop the en-
gine. Remove the key from the ignition switch.
2. Remove screws that secure sender cover to fuel
tank. Lift cover from tank.
3. Disconnect the wire harness connector from the fuel
sender.
CAUTION
When testing circuit wiring and fuel sender,
make sure wire connections are secure before
turning ignition switch to ON to prevent an explo-
sion or fire from sparks.
4. To test the circuit wiring and InfoCenter fuel gauge,
use a jumper wire to connect the two (2) terminals in the
wire harness connector. Make sure that jumper wire
connections are secure. Turn the ignition switch to the
ON/PREHEAT position. InfoCenter display should indi-
cate a full fuel tank if circuit wiring and InfoCenter are
working correctly. Turn ignition switch OFF and continue
testing fuel sender if circuit wiring and InfoCenter are ac-
ceptable.
5. Loosen hose clamps and carefully disconnect sup-
ply and return fuel hoses from fittings on the top of the
fuel sender.

sembly purposes (Fig. 79).

el sender in the fuel tank.
7. Raise fuel sender and gasket from the fuel tank.
Clean all fuel from the sender.
CAUTION
