Testing the Relay (continued)
Electrical System: Testing the Electrical Components
5. Use a multimeter (ohm setting) to measure the resistance between the
following relay terminals; refer to
A. Continuity should exists between terminals 30 and 87a.
B. There should not be continuity between terminals 30 and 87.
C. Resistance between terminals 85 and 86 (relay coil) should be from 2.3K
to 2.8K ohms.
6. Connect a multimeter (ohms setting) to relay terminals 30 and 87. Ground
the terminal 86 and apply +48 VDC to terminal 85. The relay should make
and break continuity between terminals 30 and 87 as 48 VDC is applied and
removed from terminal 85.
7. Connect a multimeter (ohms setting) to relay terminals 30 and 87a. Ground
the terminal 86 and apply +48 VDC to terminal 85. The relay should make
and break continuity between terminals 30 and 87a as 48 VDC is applied and
removed from terminal 85.
8. Replace the relay if necessary.
9. If the relay test correctly and a circuit problem still exists, check the wire
harness; refer to A Electrical Schematic-1800/2100, and 2120 (for Models
04042, 04043, 04046 and 04049 fitted with 04069) (page
10. If relay removed for testing, install the relay to the mount bracket and secure
with 2 bolts and nuts.
11. Connect the cable connector and wire harness to the relay as noted during
disassembly.
12. Install the battery cover onto the mount bracket and secure with 8 bolts.
13. Connect the battery pack; refer to
(page 5–7).
