I have a 06 Fatboy with 5800 miles on it. I started the bike up normally. After about 5 seconds the bike just died and will not even do a self test. I do hear a relay click when I turn on the switch. No lights, horn, no nothing. Battery is good. Any help?

Re: All is dead.
I'm always hestitant to offer suggestions on the newer Harleys, my experience is all on 1999 and earlier carb bikes. But try the standard stuff first. No horn or lights leads me to check my connections and fuses starting with the ground for the battery. Torque em up a little and see if it helps

If you have changed exhaust, air filter even slip ons you likely need a different modules setting or if a carb it needs jetted. My bike always "burped " until I changed over to a S&S, drastic but builder explained that slip ons and K&N changed enough to cause the burp
On the softail model Harley Davidson's the oil tank is external and sits up higher than the engine crank case and oil pump. when these bikes sit for an amount of time the oil gravitates from the tank to the crank case. starting may seem sightly harder and seem like the battery is going dead. the bike should be started in knowing that you had oil in it to start with and no giant leak puddle underneath of it. warm up the engine and then drain the oil out of the tank. the reason why your filler cap popped off is because you had probably 2 1/2 to 3 quarts to much engine oil in the bike. so drain the oil from the tank at the drain pug at the bottom of the hose on the high (right side ) of the bike where the swing arm meets the frame (it is a 5/8 socket) put the drain plug back in run the bike for about 5 minutes inspecting with a flashlight continuously that oil is circulating back into the tank. then dran it again and replace with new oil.
test or replace your ignition module,and you might find the actual prob by accident the connector for the module sometimes with age lose or only have intermittant contact.a can of electrical contact cleaner should take care of it but those symptoms scream ignition mod dont know why hd dealer couldnt find it but they dont put their best techs on older bikes
Start with the battery and make sure u have at least 12.5 volts and good cable connections
1. Are the plugs fouled ?
2.Fuel filter clogged ?
3.Check all the (vacuum) lines for tight connection
4. Sparg plug cables, coil
5.Ignition timing, sensors
Another common problem. Open transmitter, remove battery - there's a small tang dead center under battery. I think it's bent down. Use small screwdriver bend upward to act as spring against battery. Reinstall battery and cover. That should do it! Works for 80% of transmitters. Otherwise you have to take it to a dealer and they'll put it on the digital tech and relearn your code to your moduel, but battery trick works most of the time. It gets bent down being in pockets and getting the button pushed. Let me know if this worked.
Have not worked on an HD but my thoughts and additional guesses would be: 1. fuel contamination (water at bottom of tank); 2. primary pump (in my case it was inside the fuel tank & might not be present in your bike); 3. fuel lines & clamps to & from primary pump or to the carbs; 4. in line filters; 5. vacuum controlled fuel valve (oppose to the usual manual petcock) 6. if it were the MAP sensor, bike wouldn't even run a block away + idling would be rough; 7. by chance are you using a Power Commander?
Also your post "bike will start and run fine for a few blocks then die" indicates that indeed fuel got into the carbs before but not when running meaning the bike used what was inside the bowl and was not replenished. Alternately, the fuel flow to the carbs might not be sufficient and there is a leak or a blockage somewhere.
As said might not work for your bike but has come across some of the above on numerous occasions.
