Testing the Relay (continued)
Electrical System: Testing the Electrical Components
5. Using a multimeter (ohms setting), measure the coil resistance between
terminals 85 and 86. The resistance should be from 990 to 1210 ohms.
6. Verify infinite resistance (no continuity) exists between terminals 30 and 87.
7. Connect multimeter (ohms setting) leads to relay terminals 30 and 87.
Ground terminal 86 and apply +48 VDC to terminal 85 of the relay. The relay
should make and break continuity between terminals 30 and 87 as +voltage
is applied and removed from terminal 85.
8. Replace the relay as necessary.
9. If the relay tests correctly and a circuit problem still exists, check the wire
harnesses; refer to
10. Install the relay and connect the wire harness.
11. Install the battery cover onto the battery mount. Secure the battery cover
with four bolts.
12. Connect the battery pack; refer to
