Good -- Unplug the connector for shift up & Dn buttons and check for 5VDC on the Bl/R wire --- everything else plug in

Okay battery is good -- bike will start and run? -- when you turn key on bike shows neutral light on display?

HI: I am back home again --- Okay lets start with the Battery test -- place your meter leads on the battery and leave them on while doing the test -- take a reading then turn the head lights on for 30 seconds voltage will drop -- turn lights off voltage should ramp back up to what the meter read before turning lights on. what did you see.

Okay Retro I will try to keep him busy --- now unplug the 5 pin connector of ECM and check the Green wire for continuity to ground

Yes that is correct 

Ok -- Now put the jumper back in the relay connector -- unplug the ECM  -- and check for 12VDC on the R/Y wire of the 5 pin connector for ECM - black meter test lead on neg. of battery when testing.

If you don't have 12VDC on the R/Y wire of the connector -- check for continuity from the R/Y wire on that connector to the R/Y wire on the relay connector.

Also when you check for 12VDC on the shift motor was the relay plugged in?

Is your bike in Neutral when doing these tests?

Yes that the relay -- You are doing fine with your tests

Wish I had your bike in front of me ----- Do this unplug the Engine relay (4 wires on it) test the harness side for 12VDC on the R/W and Green wire on the connector

Hi: both probes in connector -- harness side

OK -- unplug the shift motor and do that test again with the jumper and check to see if you have 12VDC on the connector to the shift motor -- key on and push the shift buttons.

Did you have the jumper in place when you tried to shift?

Ok that's good -- now go to the relay connector and place a jumper wire from the R/Y and R/W wire and see if the bike will shift 

Check Bl/O wire again on the relay connector with the ECM plug in  -- both connectors on the ECM  with key on 

Was the ECM plug in and the key on when check for 12VDC on the Bl/O wire?

Hi: also do you have 12 VDC on the Bl/O wire on the same connector with the key on?

Now find the engine relay see picture -- the relay has 4 wires to it -- unplug it and check the R/W wire in the connector for 12 VDC with the key on

Hi: I am just going to jump in here while you wait for Retro ---  key off -- unplug the ECM and check for 12 VDC on 5P connector 5 wire connector for ECM  that is the R/Y wire -- should have 12vdc on the that R/Y wire with key on -- red test lead on the R/Y wire and black test lead on neg. of battery.

Hi: My 420 has the caliper mounted at the front also.

Hi: Big Welcome Here

Hi Big Welcome Here: -- You need to use a Multimeter do your testing --- unplug the connector for the Up/Dn buttons -- on the harness side you should read 5 VDC  with the red test lead on the Bl/R wire and the black test lead on the neg. of the battery -- with the key on

This was in the news last week --- Canada

Hi: Big Welcome Here.
