I am trying to connect my new taillight for my 2006 boulevard c50. I tested the wiring and was all good. Now i am trying to complete the project and have lost power to the break light and no lights on my tach for fuel and blinkers. any solutions or ideas to my problem

Question edited for clarity.
Question moved to model category.

The problem with a Trike is that the wiring will be custom. For the brake light, check the switch with a multimeter for continuity. For the lights look for a break in the wiring. There may also be a relay involved in the running lights.

When a 2005 Suzuki Boulevard C50 motorcycle spins over but doesn't crank and there is no fire, meaning no spark, it indicates a potential issue with the ignition system. Here are a few common causes to consider:
1. Faulty spark plugs: Check the spark plugs to ensure they are in good condition. If they are worn out, fouled, or damaged, they may not produce a spark. Replace any faulty spark plugs and ensure they are properly gapped.
2. Ignition coil failure: The ignition coil is responsible for generating the high voltage needed to create a spark at the spark plugs. If the ignition coil is faulty or damaged, it may not produce the necessary spark. Consider testing or replacing the ignition coil if necessary.
3. Ignition switch or wiring issue: Inspect the ignition switch and associated wiring for any loose connections, damaged wires, or faulty switches. A problem in the ignition circuit can prevent the spark from being generated. Repair or replace any faulty components as needed.
4. Faulty ignition control module: The ignition control module (ICM) controls the timing and delivery of the spark. If the ICM is defective, it may not send the signal to the ignition coil to generate a spark. Testing or replacing the ICM may be necessary.
5. Fuel delivery issue: While the symptom you described seems to indicate a lack of spark, it's worth checking the fuel system as well. Ensure the fuel tank has an adequate amount of fuel and that the fuel lines are not clogged or kinked.
It is recommended to consult a professional motorcycle mechanic or authorized Suzuki service center to diagnose and fix the issue. They will have the expertise and necessary equipment to accurately diagnose the problem with your 2005 Suzuki Boulevard C50 and perform any required repairs.

a 12 volt test lamp, or a muti-meter, are very handy tools for finding the problems like you have. to check if you have power going to the rear markers? You can trace your wires better with one of these tools, and usually fix the problem quickly. also check all your fuses in the fuse box, mabey there is a fuse for the rear markers?

THERE IS THREE BOLTS UNDER THE REAR MUDGUARD (FENDER) THEY ARE DIFFICULT to get at. once they are removed the tail light unit will pull forward.
hope this helps.
