Washed and waxed my 08 flhx. Now it won't start. I've got electrical power, but the turn signals flash back and forth crazy. Hooked up the battery charger, but the starter still won't engage

 

Sounds like the Security System has you locked out. That's why your flashers are going crazy. Replace your key fob battery.

 

Just replaced the fob battery. Might be a dud. Off to buy new batteries. Thanks

 

Did you put it in the right way in the fob?
