Easiest way in this case, hook everything up, unplug the ACRs and try to start bike.

If fuse still blows they are not your problem.

(You said you already physically checked the wires.)

If you want to test the Y/G wires for the ACRs instead of just looking at them, just unplug the Fuel Pump fuse and the fuse marked Exhaust Control, then test for ground at the Exhaust Control cavity (3B). (see my schematic in previous post)

If it is grounding then the Y/G wire for the ACRs is grounding somewhere.

I'm on board 100% that the ACR's need to be tested, the whole circuit needs to be powered up with the ECM disconnected to see if the fuse holds.

Lets do it a different way. We know that when the system relay energizes the ECM fuse blows.

Ignition off pull the System relay, Fuel Pump Fuse and disconnect the ECM. Install a jumper in the System Relay socket from the ECM - BE/GY to the Y/GN that is jumping 30 to 87 on the relay socket. Turn the ignition on and you now have powered up everything, Coil, Fuel Injectors, Purge, and ACR's, (if they are on the ECM Circuit). If the Fuse does not blow turn off ignition and install fuel pump fuse and turn ignition on again, I wouldn't let the fuel pump run but a few seconds. If the ECM fuse is still good then plug the ECM back in and try it again.

So ACR should tie into Y/GN on pin 52 and should go to pin 19 for the V/GY wire. I'm sure that on the non CVO models the ACR system s there just not active whereas when he dealer installed the stage 4 kit they activated the ACR on the ECU. The CVO model uses the same ECU as the standard model, so the hardware is the same. So I was looking again at the wiring diagrams and my bad, ground to system relay is via ECM, so to test ACRs ground pin 19 and pin 27, check for voltage at pin 52. Should have 12VDC on pin 52 when pin 27 is grounded and switches are on. There shouldn't be any tie off of the BE/GY wire outside of powering the system relay and ECU.

Good job.
Could be a shorted acr or the conductor going back to ecm. You can ohm them out.

Ok give me a rundown on that cuz the wires going to the plugs seem fine. Do I need to take the cover off to get to them or how do I test them what should I be looking for

Can you take your ohm meter and check one of the acr pins to grd?

How about pin to pin on each one?
