Kriss Motorcycle Products

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.

If you need installation support (please see note*)

1. Contact Engineering support

2. The link is used for ordering wiring diagrams.

Note
Free technical support is offered for one (1) year after purchase for Platinum products. We always try to help
but detailed support and troubleshooting isn't available after 10 or 15 years or when installing on another bike.
Electronics product support is for our customers who've already purchased products directly from Kriss.
Free support does not cover wiring diagrams which are covered under the "Lifetime Wiring Diagrams" program.

The engineering dept. doesn't handle pre-sales questions regarding which item to select for your motorcycle or operation.

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: My lights are flickering as I ride. Answer: Suggested he check the ground connection of the lights to the mounting bracket. He reported that there was dirt and grime between the bracket were it clamps to the crash bars.
Question: How do I bench test the Driving Light Unit? Answer: Attach the Green ground wire a battery negative first. Connect a small bulb or test light to each output wire, these are the Red and Black wires. Connect the power wire (yellow) to the positive from the battery. The lights will come on at the dim setting. Apply +12 volt to the blue wire (high beam) and the lights will change to full power. If the Pegasus II or Police intercepter models are being tested then apply +12 volts to the Yellow/Red wire which will cause the two bulbs to wigwag. During the wigwag fuction the high/low beam functions are overriden. If the unit passes these tests the unit is functioning properly.

Always use a test light when checking circuits.
