Advanced Troubleshooting Techniques

If the initial diagnostic steps don’t reveal the source of the problem, you may need to use more advanced troubleshooting techniques. Some of these techniques include:

• Checking the wiring harness for any signs of damage or wear
• Testing the circuit to see if there is any resistance or voltage drop
• Checking the relay to see if it is functioning properly
• Checking the ground connection to make sure it is secure

It’s important to note that these advanced troubleshooting techniques should only be attempted by experienced mechanics. If you’re not comfortable working with electrical systems, it’s best to take your motorcycle to a professional mechanic for diagnosis and repair.

In conclusion, diagnosing a B1350 trouble code requires a methodical approach and a good understanding of the electrical systems in your Harley-Davidson motorcycle. By following the steps outlined in this section, you should be able to identify the root cause of the problem and take the necessary steps to fix it.

Electrical Components Involved

When you encounter the B1350 code on your Harley-Davidson, it means that the heated backlite relay is shorted to ground. This can be caused by a variety of issues, including damaged electrical components, poor electrical connections, or faulty Body Control Module (BCM). To diagnose the problem, you need to inspect the related wiring harness and connectors, and check for damaged components and broken, bent, pushed out, or corroded connector pins.

Here are some of the electrical components involved in the B1350 code:

Battery and Charging System

The battery and charging system are essential components of your Harley-Davidson that provide power to various electrical systems, including the BCM and the heated backlite relay. If your battery is weak or not charging properly, it can cause electrical problems that may trigger the B1350 code. To avoid this, you should check your battery and charging system regularly and replace any faulty components.

Body Control Module (BCM)

The BCM is a critical component of your Harley-Davidson’s electrical system that controls various functions, including the heated backlite relay. If your BCM is faulty or not communicating properly with other electrical components, it can cause the B1350 code to appear. To diagnose this problem, you need to check the BCM for any signs of damage or malfunction and replace it if necessary.

Relay and Fuse Checks

The heated backlite relay is responsible for controlling the rear windshield’s heating element. If the relay is shorted to ground, it can cause the B1350 code to appear. To diagnose this problem, you need to check the relay for any signs of damage or malfunction and replace it if necessary. You should also check the fuses related to the heated backlite relay and replace any blown fuses.

In conclusion, the B1350 code on your Harley-Davidson can be caused by various electrical problems, including damaged components, poor electrical connections, or faulty BCM. To diagnose the problem, you need to inspect the related wiring harness and connectors, and check for damaged components and broken, bent, pushed out, or corroded connector pins.
