TEST PROCEDURE 5 – CHARGER DC CIRCUIT CONTINUITY TEST
Test Procedure 5A – DS Villager 4
See General Warning, Section 1, Page 1-1.
1. Disconnect the AC cord from the wall outlet.
2. Disconnect the batteries as instructed.
See General Warning on page 1-1.
3. Disconnect the DC cord blue wire (17) from the 3-way wire adapter (18) at the sense lead fuse (20)
(Figure 4-29, Page 4-36)
.
4. Disconnect the DC cord red wire from the positive (+) post of battery no. 1.
5. Disconnect the DC cord black wire (19) from the charger receptacle fuse link
(Figure 4-29, Page 4-36)
.
6. Using a continuity tester (CCI P/N 1011273) or multimeter set to 200 ohms, connect the test probes to
the DC cord black wire and the DC cord red wire
(Figure 4-16, Page 4-18)
. Note the reading.
7. Reverse the test probes and check the DC cord again
(Figure 4-17, Page 4-18)
. The circuit should show
continuity in only one direction.
8. If the circuit does not show continuity in either direction and the charger fuse is not blown, individually
check all connections and the continuity of the DC cord and ammeter.
See Test Procedure 8 – Conti-
nuity on page 4-21.
Also check the diodes (heatsink).
See Test Procedure 4 – Diodes on page 4-16.
9. If the circuit shows continuity in both directions, a short circuit exists in the charger DC circuit, usually
caused by failed diodes.
See Test Procedure 4 – Diodes on page 4-16.
If diodes have not failed, check
the DC cord for a short circuit.
See Test Procedure 8 – Continuity on page 4-21.
10. Remove the DC cord blue wire from the control board and check continuity between the DC cord red,
black, and blue wires
(Figure 4-5, Page 4-7)
. There should be no continuity.
