PROCEDURE:
1. Set a voltmeter to measure resistance.
2. Disconnect the J2 connector from the printed circuit board.
3. Connect one meter test lead to Wire TR2 at Terminal Block 1
(TB1). See Figure 6-62. Connect the other meter test lead to
pin location J2-6 on the J2 Connector previously removed. Be
careful not to damage the pin connectors with the test leads.
Continuity should be measured.
4. Connect one meter test lead to Wire TR1 at Terminal Block 1
(TB1). See Figure 6-63. Connect the other meter test lead to
pin location J2-3 on the J2 Connector previously removed. Be
careful not to damage the pin connectors with the test leads.
Continuity should be measured.
RESULTS:
1. Repair or replace defective wiring.
2. If wiring tests good replace printed circuit board.
TEST 56 - CHOKE TEST
PROCEDURE:
If the generator is surging it may have a carburetion
problem. A lean condition can cause erratic RPM.
Slowly pull the choke out to see if surging stops. If it
does stop, carburetion should be checked.
