After driving it a long period of time (10-15 miles), it will cut out, back fire, and flashing code. HD did a dinogstic said "Voltage out of range". I have replaced the voltage regulator and engine timing sensor. Still having the problem. Bike starts fine, it's not like the battery is low, but when it starts flashing codes the headlight goes dim until the code finish flashing then it goes bright again. Any suggestions of what I need to do next?
