Won't start
 

Starting issues. 2012 FLHTK. Turn on ignition oil pressure light comes on. Nothing else. No lights radio etc. switch is on. No cranking radio. Nothing but oil pressure light. All other readout is dead. any ideas? New battery installed last summer. Heated garage storage.

Doesn't matter the battery was installed last year. Needs to be load tested.

All winter, even in a heated garage, is a long time for a battery to sit and not be on a maintainer. You probably have a clock, security, and perhaps other "keep alive" memories that slowly, but constantly drain the battery.

Could it be a fuse of some kind? In my case mine started but I had no neutral light no gas gauge and no speedometer, it was a fuse.

It was running last year? Put on charger or jump pack and see if any other lights come on. Its odd nothing else came on. Maybe other lights come off BCM? Does it have BCM?

Was it on charger? If not just put on charger over night.

The very first step is to check the battery voltage with a voltmeter. Until we have that basic information anything we tell you is just a wild guess.

Thanks.
 

FOLLOW UP- Battery was shot. Yes it was on trickle all winter. That's what kinda threw me. Thanks for the input guys. Much appreciated

What do you mean by “trickle”. Which one?

4 amp trickle charger. I know it works because I just used it on my truck after I left my lights on overnight

If I were you, I think I would switch your bike to a battery maintainer like . That trickle charger is probably what killed your battery.
