Question Dead battery, dead bike
I left my 2001 Fatboy off the trickle charger and the battery drained with the alarm set. After charging the battery back up, the bike will not fire. Starter cranks good, lots of fuel from the smell, but bike will not fire up. No pops, belches or anything indicating the plugs are firing. Getting ready to break out the multimeter. Could something have coincidentally failed? Is the alarm turning something off? I have a new coil just in case. Is there a way to test the coil? Repair manual is no help at all. I saw another mention about fuses. Thought I checked these, but will go through them again. Any thoughts?

you say you're getting fuel...do you have spark?

Stupid question, but is the run switch in the run position?

Yes the switch is in the run position. I tried the old method of grounding the plug to check spark, but saw nothing. I picked up a nifty item that goes between the plug and the wire and lights up when there is juice. Going to try that tonight. No spark is my first choice since I get no popping or belching when it is say flooded. It just cranks. That is why my first thought went to a bad coil. Wanted to test it, but cannot find any info on how to do it. Guess I need to just throw on the new one and see if that works. I hate doing the "swap out parts" method of troubleshooting.

How about the fob battery, assuming your alarm system has a fob?

Alarm seems to activate and deactivate fine with the fob. Button type.

Damn it. Looks like the battery needs replacing now. Had it on the charger all night and now will not take a charge. Just one thing after another. Did replace the fob battery just in case.

New battery in and charging. Tried to rurn it over and looks like no juice is getting to the plugs. Using device between plug and coil that lights if there is power. Looks like either the coil, gets replaced tomorrow, or ignition module? Anyone know how to read the trouble codes for a 2001 Fatboy? Turning on ignition with odometer reset held in I get d01clr in the display. each press of the reset advances the number 1, d02clr, d03clr etc. Then goes to PPS I think on the next press and then 82883. should have written this down. Anyone know how to read the codes?
