2014 R3R begins to start, then cuts off

Sounds like the battery to me too. A charged battery will be over 12.8 v with no load.
Anything less than this means the battery is either not charged or on its merry way to recycling.

Do not spray WD 40 in there, never on electrical contacts, use contact cleaner, hexane, zero residue.

Another way to check the battery is to check the voltage while engaging the starter. Record what the voltage drops to if possible. If it is dropping below 9.5 volts, charge/replace it. If your voltmeter has a peak hold function, you can see how low the voltage drops before it kicks out. Again, you should be above 12.8 volts or higher when starting.

Def Battery - Jump it to your car and try - plenty of juice.

I really appreciate all the advice, guys. A weak battery on my other bike usually means a sluggish start and instrument panels being dim, and this seemed very different.

But, I left it on the tender overnight and measured voltage this morning -- it did start, but dropped down to 5-something volts while doing so.

I'll do a bit more troubleshooting and get a new battery.

I am at a loss. My 2014 Roadster won't start. I left it out during the rain, and have developed the following intermittent issue.

The "N" is lit up when I attempt to start. As soon as I hit start the "N" is replaced by "--". The relay clicks and the starter motor attempts to fire, but immediately cuts out. One time it turned over once before cutting out.

Randomly it started working for a day, but the issue has recurred.

I replaced the gear position sensor; did not help.
Clutch is pulled in and kickstand is up.
Kill switch is on.
Ignition is on.
Battery is charged.
I have tightened the battery cables.

I appreciate any ideas.

Seeing your just south of me or southwest. You didn't leave it out when Dorian rolled through? If so and your close to the coast then might have got pretty wet. I know the tide was almost 5 foot higher in my back yard

Its usually the CCA Cold Cranking Amps (rather than just the voltage). Looked at the Video, seems like the battery to me too. Cheers

I appreciate the input! Should I disassemble the starter switch to clean it and check the ground?

No need to disassemble the switch, some pressurized air would do it. It definitely seems like the battery. See my earlier post about CCAs.
