Troubleshooting - Check 12v Power Connectors

If your 12v accessory battery LED is lit and you have no power to the relay board, you'll need to check the 12v power connectors between the battery and the relay pack. At this point, you may want to refer to the 12v accessory wiring diagram.

Locate Modular Connector 'P1' 

Just below the 12v accessory battery pack is the area where all the bike's modular connectors are located (about 20 or so connectors plugged together). Typically, there is one or two zip-ties wrapped around the bundle to keep the bundle from hitting the switch on the side of the 12v battery (would disable bike).

Carefully remove the zip-ties and locate modular connector 'P1' coming from the 12v accessory battery pack.

 

Helpful Hint: It is not always necessary to disconnect modular connectors to get electrical measurements. Most multimeter lead tips are able to contact connector pins where the wire is inserted into the connector.

 

Warning: When disconnecting modular connectors, never pull on the wires. Depress the locking tab to unlock the connector and pull apart by the plastic casing.


Check Voltage Across 'P1' Connector

Using a digital multimeter, verify 12vdc on the 'P1' connector.

  • Is there 12vdc across the terminals?
Yes (Normal) Continue
No (Abnormal) Bad Connector or Battery

 

 

 

Check Voltage on 'P2' Connector

Using a digital multimeter, verify 12vdc on both pins of the 'P2' connector.

  • Is there 12vdc on both the terminals?
Yes (Normal) Continue
No (Abnormal) Check Key Switch/Wiring

 

 

 

Check for Open Circuit

If you have 12vdc at 'P1' and 'P2', and it is not present at the relay module, then you have an open circuit in the wiring between 'P2' and the relay module.

Refer to the 12v accessory wiring diagram.

Solution: Identify open circuit and restore continuity.
