I have a 2002 Wide Glide that will Crank but won't start. I have no fire at the plugs. I have replaced the Ignition Coil and Speed Sensor and still have the same problems. I have 12 volts going to the Ignition Coil and all fuses are good. I looked for a 40 amp Maxi-Fuse and found nothing. Apparently this Bike was not built with a 40 amp fuse. I checked for voltage on the 2 wire weather pack connector underneath the seat that feeds voltage to the speed sensor and have no voltage. What feeds 12 volts to the speed sensor? Does the ECM provide the voltage for the Speed Sensor? Thanks
The speedometer gets the 12 volts power from the O/W acc wire.
According to the '02 FXDWG instruments wiring diagram the 3 wire speed sensor receives 12 volts power in the red wire from the speedometer (see image below)
Not sure what you mean with "the 2 wire weather pack connector underneath the seat that feeds voltage to the speed sensor"
Did you preform a Diagnostic Scan for ERRORS?????? If you have voltage to the coil but no spark, look at the spark plugs, plug cables and the Crank Position Sensor. The Speed Sensor doesn't have anything to do with spark.
Many Thanks for your reply and info you provided for me. The OEM Speed Sensor on bike has only has 2 wires, Red and Black. I traced the wires from my speed sensor and they run all the way back to a 2 wire connector underneath the seat from there the Red and Black wires go downward towards the fuse box and ECM. I can't visually follow the wires from this point.
I tried the diagnostic scan and nothing happens. No codes....I held the trip reset button down and nothing happened. I was searching on the internet in regards to the speed sensor and read that if the speed sensor is bad you will have no fire to the plugs.You have a good point there because if I have 12 volts to the Coil there should voltage going to the spark plugs.
