Resistors cut Voltage by adding...


wait for it...


resistance to a circuit. A common use for resistors in a Direct Current LED turn signal circuit would be to make a regular-ol' thermal turn-signal flasher work (tick-tock... tick-tock...)

Without enough resistance in an LED turn signal circuit (using an older thermal flasher), the signals come on, but won't flash.

You can make it easy on yourself and simply install an electronic flasher specifically made for low-resistance LED lights. NAPA and better parts stores have them in stock, just make sure it's for LED's.


Alternating Current does just that... alternates direction, back-and-forth 60 times a second. In order to convert Alternating Current to Direct Current (Rectifying), you need a number of Diodes (not resistors) working in parallel.

Diodes are like one-way check valves for electricity. Flowing through a Diode, current can flow only one direction, but not the other. Ta-da! Direct Current (one-way only). This is the Rectifier portion of a Regulator / Rectifier. The Regulator limits the output Voltage to 12.5 to 14.7 or so, while the Rectifier converts AC to DC.

Baja Designs and others sell a kit that includes nearly everything needed to convert an XR4 over to usable DC (for lights, battery, GPS power, etc.)
