Glow and Start Relays
The glow relay and the start relay are mounted to the
right side frame member below the operator’s seat.
Note: Prior to taking small resistance readings with a
digitalmulti meter,short the test leadstogether.The me-
ter will display a small resistance value (usually 0.5
ohms or less). This resistance is due to the internal re-
sistance of the meter and test leads. Subtract this value
fromfrom the measuredvalue of thecomponent you are
testing.
1. Verify coil resistance between terminals 86 and 85
with a multimeter (ohms setting).
A. For the glow relay, resistance should be from 41
to 51 ohms (Fig. 17).
B. For the start relay, resistance should be from 80
to 90 ohms (Fig. 18).
2. Ground terminal 86 and apply +12 VDC to terminal
85. The relay should pick up making the sound of a
sharp click.
A. For the glow relay resistance between terminals
30 and 87 should be 1 ohm or less.
B. For the start relay, resistance between terminals
30 and 87A should read as an open circuit.
3. Remove+12VDCfromterminal85.Therelayshould
drop out making the sound of a sharp click.
A. For the glow relay resistance between terminals
30 and 87 should read as an open circuit.
B. For the start relay, resistance between terminals
30 and 87A should be 1 ohm or less.
4. Disconnect voltage and leads from all terminals.
