2014 SGS is down for a few winter time repairs and projects. While I have access to the ACR connectors, does anyone know of a quick test I can do to see if they are operating correctly, WITHOUT pulling them out to bench test? I really don't want to pull the rocker boxes to remove them. After the bike is back up and running, I understand that I can do a compression test to see if they are operating or not, but if they aren't, then I have to take the tank and all the goodies off again. Can I jump 12v to the wire(s) going to the ACR? If so, which one? The wiring diagram in the FSM shows two wires and the labeling is a bit confusing. Anyone do this test before? TIA......
Only a GUESS. What I would try is to remove the small wire from the starter solenoid (so the engine won't crank) and with a stethoscope (or long screw driver to my ear and the CR, press the starter switch to see if I can hear the "click" of the CR. If that won't work, hopefully someone who KNOWS can tell what to do.
So, I tried the stethoscope test by reinstalling the main fuse, my starter is laying on the shop floor for part of this teardown, turned the ignition switch and kill switch on, and then hit the starter button. There is no click or anything coming out of either one of the ACR's.
I tested the voltage across the two wires feeding the acrs and there was 8 to 9 volts DC across them. While I held the multimeter leads, I had Mrs.MJ push the start button and there was no difference in voltage. Same voltage whether I had the kill switch on or off. So then I checked it with the ignition switch and the kill switch both off and I still have 9 volts. I'm confused. There's got to be a way to test these while they're still in the bike.
Trying to jog my memory
We put a 15 103 in my 08 ultra that didn't have ACRs When first trying start it we rigged up a jumper wires to the ACRs.
It helped for making a test start. We had a real hard time making sure it would work just listening.
I ended up getting a finger on the ACR one at a time and could feel it was the only we knew for sure.
Haven't needed to monkey with my ACRs yet. Do I understand that there are two wires to each ACR? If so, they may work by the start circuit closing the ground. Have a wiring schematic for your bike? 9 volts makes me wonder if a jumper with 12 volts would damage the ACRs, I have no idea if 9 volts is correct. Still hoping for an authority on this.
If I'm looking at a schematic right the violet / green wire to the ACR's is a constant system voltage with ing on.
The Light green/ Red wire goes to the ECM and the ACR's are controlled by grounding that circuit.
I haven't learned to put a schematic up like some.
If you can get to HD SIP wiring schematics look up your bike and go to Pg 7 shows what I'm talking about.
That's kind of the same thing I'm seeing WP but I hope me putting 12 volts to those things didn't backfeed into the ECM and fry that thing! I was just thinking this was kind of like a basic solenoid where the coil doesn't care which way the current flows through it. A lot of solenoids that I've dealt with don't even have two different colored wires on them.
Each acr has a plug end.
We put a 12v jumper wire to a terminal on the front ACR connector.
Then grounded the other terminal to test Ended up feeling it rather than hearing it
You already having ACRs I wonder if just grounding the LGRN/ R wouldn't let ya test.
With the ecm not grounding the circuit (since your not hitting the start button)while your testing I don't see how it would hurt anything.

They are when isolated from a circuit.
The wire color doesn't start until the harness the ACRs plug into going to the the ECM and connects to power somewhere IIRC
