CHECK GENCONR RELAY COIL
•
TRIGGER–ON: Generator contactor relay (GENCONR) circuit is shorted. (The relay output from
the microprocessor (4MP7) is negative, so the circuit will not be shorted to ground, but is shorted
either within the relay coil itself, or to a positive wire.)
•
UNIT CONTROL: Engine and Standby Operation: alarm only.
•
RESET CONDITION: Auto Reset or alarm may be manually reset via keypad or by turning the unit
off, then back on again.
NOTE: Follow the steps below until a problem is found. Once a repair or correction has been made, the active
alarm should clear itself (see reset condition above). Operate the unit through the appropriate modes to see if
any active alarm occurs. Continue with the steps below as necessary.
1
Check GENCONR
a. Inspect generator contactor relay
coil and terminals.
No damage to coil.
No damage or corrosion.
b. Check contactor coil resistance.
Refer to Section 2.12 for correct electrical values.
Cannot be opened (infinite ohms), shorted (Zero
Ohms) or shorted to ground.
c. Check amp draw of coil.
Refer to Section 2.12 for correct electrical values.
Use ammeter.
2
Check GENCONR Current Draw
Use Component Test Mode to test
actual current draw of the circuit.
(Refer to Section 5.2.2.)
Refer to Section 2.12 for correct electrical values.
View current draw in Data List.
3
Check GENCONR Wiring
Inspect harness & control box con-
nector pins & terminals. (See wiring
schematic Section 10.)
No physical damage to harness.
No damage, moisture, or corrosion in connectors.
