Your friendly local HD dealer will check that battery free of charge. (ha ha). Yup, believe it or not they will load test it and give you a receipt indicating the battery condition. I would do that regardless.

Funny thing. On my shovel the other day, it did nearly the same thing. I moved the switch around a little and the old girl roared to life.

I'm not sure where the nearest dealer is in Ken's part of Alaska.

 

We have one about 12 miles away from here. Now days they sell a little bit of everything, from weed whackers to Harleys and several other brands. They don't carry much for a 25 year old evo though. https://farthestnorthhd.com/

Okay got it figured out, it was the BATTERY.
I pulled the battery and charged for a couple hours and the voltage actually went down to 10.5 volts.
I pulled the battery out of my 1989 fxstc and put it in the Fatboy, It started right up!!
Thank for all you suggestions, I never would have thought a battery with 12 1/2 volt would not at least run the lights.
