Default Check engine light

Recently my went to start my bike and the battery was dead. I think as a result of the security system going off for too long, or possibly the engine shut off let on (pretty sure it was off), or faulty battery tender. Got the battery charged, started the bike, check engine light came on. Called the local dealership and explained this and there suggestion was “run it for 50 miles or so and see if it goes off”. I did, it didn’t. Called back and they said trailer it in, don’t want to ride it without knowing what’s wrong.

Im assuming the light came on because of a sensor with low battery (just a guess I know nothing about bikes). They can’t get the bike in for 2 weeks. I’m debating pulling the battery terminals and reconnecting to see if that resets the light.

Am I headed in the right direction or do I wait 2 weeks?

the bike is a 2018 fatboy with 620 miles on it

That just seems like such bad advise, instead of checking what the code actually is first. It is as if the guy couldn't be bothered to spend the time to help you out.

You still have a warranty, I'd assume, on a 2018 bike. Let the dealer (maybe a different dealer!) work with it- do you have other dealers in the area that could maybe look at the bike sooner? You don't have to use the dealer where you bought the bike, any HD dealer can process warranty work for your bike.

In the meantime, ensure the battery is fully charged, pull the main fuse, wait a few minutes and power back up- if that doesn't clear the check engine light, you'd need to pull the codes and go from there.

The order of doing things must be to first read the codes following the link shanneba posted.

Once the list has been produced they can be discussed with a dealer to see if they are good or bad as to whether the bike should be ridden or trailored to the shop.

I agree with a bike under warranty it is a dealer to fix issue but you can help yourself to help your dealer work out what to do.

After that you can clear the codes and see if they come back or whether it was a product of a flat battery.

Dead battery does make the check engine light come on. So I found out.

By using the run/stop switch as a mode to shut off the engine a lot of riders tend to forget about the ignition switch going to "O F F" . Not saying that's what OP did but the MOCO has insured more batteries are being sold.

How do I check the code(s)?

also unless I’m completely wrong, there is no ignition switch on the 2018. Simply be in range with the FOB and start the bike.
