I have a 2012 260 and it is not getting spark. I ordered a new ECU as the tech from BMS said. But it's still not starting. Any wiring manual available? Any suggestions?

Wiring diagram should have come with the ECU, or are you looking for the scoot wiring. Make sure the killswitch is on the run postion, Also do you know if the CDI is a DC or AC CDI? Also make sure your fuses are good the ECU gets fed 12v so check the POWER going to the ECU. Also if you were messing around in there or doing things make sure the ground wire to the motor to frame is making good contact. No Spark at this time could be many things, bad coil, spark plug boot cap, bad cdi bad pickup, bad ground, bad ignition switch etc..

What works and what does not work with the KEY ON.

Here is a link to the wiring diagram for this scooter in the NOT efi version. Hopefully it may give you some insight. it's like 67megs so it takes a while to download.

FWIW, when I had spark problems on my non-efi vog it was a bad spark plug boot once, and once the brown and yellow wire going into the cdi was loose.
