| Installation instructions must be followed exactly and all steps completed prior to applying power or the unit will be damaged. Connecting the unit backwards will damage the unit. |

Problem
|
|
| We are using this particular
example to reveal what takes place more times than not. We are providing this exchange so you can see the results of an incorrect installation. The customer bought a closeout model headlight modulator and returned it because he said it didn't work. We didn't find anything wrong and agreed to give him credit toward one of the newer models. He insisted that he knew what he was doing and did everything correctly. Customer: I installed the replacement modulator tonight and it doesn't work either. It actually blows the motorcycle fuse when switched On. Prior to installing the unit I took great pains to insure it was connected properly and used a multi meter to confirm each wire of my circuit plug. I also tried it on my bench power supply and it makes the supply go into overload protection. I'm an electrical engineer so I understand electronics. Can I send this thing back for a refund? As much as I want it to work, I'm tired of messing with it. Us: Sorry but that won't be possible. I can tell you without any doubt that you've connected the unit backwards. If it's blowing the fuse or putting a power supply in overload then you've blown the suppression diode in the circuit which prevents total destruction. Note: We sent him a photo of the component in question and suggested he open the case and check the diode with an ohmmeter. Customer: Thanks for the picture and explanation. I took the box apart and checked the diode. Not only was it shorted, but the top was blown off. I replaced the diode and hooked it up to my bench power supply. It worked fine. Before I hook it to the bike I'm going to go through the wiring again and double check things. |

Be sure to check your battery, especially after all the testing on an installation. A customer called explaining he was sure everything was connected properly but the unit he was installing would not work properly. We suggested he remove the unit and perform a bench test which resulted in proper operation. He was really puzzled. We suggested that the battery should be checked as these small batteries can be depleted quickly when the electrical system and all the lights are on while installing an electrical device. He called later advising that he'd charged the battery and now everything works as advertised. |

WARNING ABOUT JUMP STARTING A customer recently had a dead battery after leaving the key on overnight and tried to start the motorcycle with a battery charger, rather than jumping from a battery, which caused a high voltage spike that damaged one of our brake light devices. Always charge the battery for a couple of hours and then disconnect the charger before cranking the engine which creates a very high load demand. It's best to jump with a battery that's not being charged at the time, either by portable charger or a running automobile engine. Voltage spikes over 18 volts can damage radios, GPS units and other electronics. Our units contain over voltage protection up to 18 volts without damage. Above that our protection component will short to protect the circuit board. |
| Question 1: Where is the wiring located for my brake light for connection of the unit. Answer: Remove the seat and note the main wiring harness that connects to the rear of the bike to power the lights. The respective wires are located inside this group of wires that are wrapped in electrical tape. |
|
| Question 2: Programming
doesn't seem to work. I touched the wire and counted the flashes but
unit didn't change program when the unit was turned back on. Answer: After counting the programming flashes and disconnecting the program wire the power must be left on the unit for about five seconds before turning the power off and back on. This is because the programming is not completed for several seconds after the program wire is removed from +12 volts. Also, we've found that some people wait until after the desired number of program flashes are completed. The wire must be disconnected when the last flash comes on and disconnected rather than after the light goes out. The result is the program is now in the next program instead of the desired program. |
|
| Question 3: After installation
the unit didn't flash correctly when the brakes were applied. Sent the
unit in for testing which confirmed nothing wrong. After installing
again the same problem resulted. Answer: It turned out that the battery was run down during installation and testing and the engine wasn't started or the battery charged. If the battery voltage is below 12 volts (normal operating voltage is 13.8- 14.2) the brake sensing circuit voltage will be low and the unit won't function properly. |

| This installation problem is provided mainly to show that the wiring isn't necessarily correct as one may believe. Question 4: Unit is wired per directions. Brake lights operate normally but do not flash. The unit is flashing on the output line but the led brake lights just have a barely detectable flicker. I have checked all wiring. Brakes operate normally from hand and foot brake activation and there is only one brake wire to the brake lights. help!!!!!!!!!!!!!! Answer: Thanks for the advice regarding my problem. Found I had wired incorrectly from your red wire to brake light which prevented designed operations to occur. Every thing works now. Conclusion about this mystery--- operator error. I had hooked the red output wire to a ground wire. dumb de dumb dumb !!!! thanks again. |

| TIPS - | |
| Question: How
do I bench test the Brake Light Flasher Unit? Answer: Connect the Red output wire to a 12 volt bulb (even a test light is OK). Attach the Green ground wire to battery negative first and then Yellow/Red to battery positive. The light should run through a flash sequence. From the factory it's programmed for about four flashes and the it will stop and remain steady on. Remove the positive wire (yellow/red) from the battery and the light will go out. Each time this wire is connected to the battery the flash sequence will be activated. If the unit passes this test the unit is functioning properly. |

 Always use a test light when checking circuits. |
