Tech Support: Halogen Lights

1. All four stroke and some two stroke quads have batteries. Batteries require DC power, hence the need for a regulator/rectifier.
2. All quads will have a regulator or regulator/rectifier somewhere off the stator to regulate the voltage coming off the stator down to 12 volts max.
3. Halogen lights are AC, but can use DC power from the battery or AC power directly from the regulator/stator. (NO MORE THAN 12 VOLTS.)
4. There are usually three wires coming off each stock light. One will be a ground wire (usually black or green.) The other two will be positive leads (usually from high and low beams.) Trail Tech lights must be connected one to ground, the other to positive.
5. The stock switch on any quad should be able to comfortably handle 100 watts of light. Any more, and a separate switch and fuse should be considered.

Troubleshooting for all quads:

1. Use a voltmeter to measure the voltage across the two leads coming from one of the Trail Tech lights. To do this, start the quad and turn the light switch to on. Use the voltmeter contacts to measure the voltage between the two wires. If the voltage is higher than 12 volts, the regulator is either not working, or has somehow been disconnected. It is important to start the quad to test the voltage across the leads, because quads with batteries can power the lights off the battery when the quad is turned off. The battery will produce 12 volts.
2. Banshee's (which don't have batteries) should put a voltmeter across the two leads on any one of the lights to check for voltage. There should be no voltage except when the bike is running. If the voltage goes over 13.5, the regulator is not working. The voltage regulator may have been 'wired around'. If there is no regulator, add one.

1. If the lights flicker and dim at low speeds, consider using lights with a lower wattage rating.
2. The stator may not be working properly.
3. The wattage of the lights combined may be too much for the stator. Measure voltage across the two light leads when the system is on. If it is less than 12 volts, there is not enough power for the lights.
4. Remove one of the lights. If the remaining light gets brighter, then there probably isn't enough power coming from the stator.
5. Machines with no battery will increase light brightness when the engine revs higher. The lights get brighter because the machine produces more power.
