6.
Use multimeter to check diode. Set meter to
above 200 mV scale. Place probes on each
end of diode. Switch probes. Multimeter
reading will be infinity or resistance in either
position. One position must read infinity and
the other resistance and vice versa for diode
to operates properly.
Use multimeter to check motor resistor. Place
probes on resistor leads. Multimeter should
read 0 ohms resistance. Replace resistor if
reading is infinity.
INSTALL
7. Install motor resistor (1) on bracket (2) with
screw (3) and nut (4).
8. Secure motor resistor (1) leads to terminals
No. 4 and No. 6 of terminal board (5).
9. Install diode (6) in holder (7).
10. Install guard (8) on heater (9). Secure with
four screws (10).
FOLLOW-THROUGH STEPS
1. Install engine coolant heater in carrier
(see your -20).
