the engine light means you have stored diagnostic codes.

the ONLY way to retrieve the codes on your bike is with a HD diagnostic test lamp (HD-41197) or the HD "scanalyzer" test instrument. these are ONLY available from your HD dealership.

if it were me and I had your bike, I would purchase one or both of those specialty tools.

the engine light could mean anything from high or low charging system voltage to a failed sensor.

I would measure the battery voltage with the engine at 2,000 rpm (fast idle) to ensure the charging voltage was around 14.2 vdc.

as long as you bike has no issue, there is nothing else you can do until something fails and leaves you stranded.
