CHAPTER 4 OPERATION
4.1 Diagnostics
When the bike is first powered up, check the diagnostic LEDs on the label
side of the EHC. If any of the LEDs are illuminated, the circuit whose label is
next to the LED is either shorted to ground, or overloaded. This is generally
due to a pinched bare wire, a faulty component, or use of components with
excessive current draw (for example, too many lights on the headlight
circuit).
Note: The current rating of the circuit protectors are affected by temperature, so
care should be taken not to mount the EHC too close to the engine or
exhaust system.
Note: Always turn the power off after an LED has been activated to resent the
protection circuit.
If no LEDs are lit up, but the turn signals and dash indicators do not function
properly, check that the EHC main ground wire (J4, Pin 4), has a good, solid
connection to the chassis ground (such as the battery negative terminal or a
paint-free boss on the frame).

APPENDIX A FREQUENTLY ASKED QUESTIONS
I can’t read the pin numbers on the connectors.
Try rubbing a crayon or pencil across the back face of the connector. This
will cause the numbers to stand out more clearly. Also, the number “1”
terminal is designated by a rib on the side of the connector.
I am not using standard-type handlebar controls. How do I wire the
“right” and “left” harness connectors?
Even if you use discrete switches instead of handlebar controls, the wiring
diagram is the same. Since most of the switches are two-terminal types, the
wire color on the diagram is not important. For example, if you were to
reverse the horn switch terminals, the harness will still function properly.
