(2) Relays (ROPS Model)
Checking Connector Voltage
1. Measure the voltage with a voltmeter across the battery terminal
and chassis as table below.
2. If the voltage differs from the battery voltage, the wiring harness
or fuse is faulty.

Functional Check
NOTE
• The relays described here are used same ones so that these
are interchangeable.
1. Apply battery voltage across the terminals a and c, and check for
continuity across the terminals d and e.
2. If continuity is not established across terminals d and e, replace
it.
