1. Fuel sender
• Remove the fuel sender to the fuel tank • Disconnect the fuel sender coupler from the wireharness. • Connect the pocket tester (W x 10) to the fuel sen- der coupler lead.
Tester (+) lead—(Green terminal Tester (-) lead—(Black terminal
• Check the sender for specified resistance
	Flat Position	Specific resistance
UP	4 ~ 10 Ω
DOWN	90 ~ 100 Ω

If the fuel gauge fails to operate.

3. Fuel gauge
• Connect the fuel sender to wireharness. • Move the float to “UP” Ø or “DOWN” Ø
• Turn the main switch to “ON”. • Check that the fuel gauge needle moves “F” or “E”.
Float position	needle moves
FLOAT “UP”Ø	“F”
FLOAT “DOWN”Ø	“E”

NOTE:

Before reading the meter, maintain the float for more than three minutes at the “UP” or “DOWN” position.

DOES NOT MOVE

Replace the fuel gauge.

2. Voltage

• Connect the pocket tester (DC20V) to the fuel gauge coupler.

Tester (+) lead—(Brown terminal Tester (-) lead—( Frame ground

MOVES

• Turn the main switch to “ON”

• Check for voltage (12V) of the “Brown” lead on the fuel sender.
