Was wondering if anyone knew best way to disable ACR on 2017 dyna low rider. I am trying to do a compression test and I do have a shop manual but I don't see where it says how to disable ACR. In fact it says disconnect the ACR if your bike is so equipped. That confuses me more as I thought all of the Dyna 103 models had auto compression release.
The releases won't let cylinder compression build to over 125 psi. minimum of 175 psi is minimum with them off. So its a matter of accuracy for test. I do not have a power vision but I do know these things are electric and there must be a fuse to pull or relay or some plug on the ACR themselves to turn off. I just don't know where to find the connection to disable. I don't think a dealer visit is needed to shut these off.
There is a wire with a connector the goes to them on the top of the cylinder should be able to disconnect those somewhere.
They should be visible from the primary side
Man, that pic looks so simple but not so much when u look at the area they are supposed to be. Maybe with the tank off. There must be something that can be removed, like a fuse or relay under side access area. I was hoping the shop manual called that out but not a lot around that topic that I could find.
Learned today that my FP3 can turn them off as well. Turned off and re flashed. You can hear the bike struggle on start through extra compression so it definitely works. Awesome tool in FP3.
