I have not had good luck with "gel" batteries on motorcycles. they are not the correct type of battery for use on a motorcycle and are incompatible with the charging system on your Harley.

that said, I need more information on what's going on right now.

measure the battery voltage under the following conditions:

- ignition OFF.

- ignition ON.

- with the start button depressed.

- with the engine at 2,000 rpm (fast idle)

let me know what you find,
