Hi Everyone,
I have been troubleshooting an issue that led me to replace the CDL actuator.
I have a 1996 series 80 with a CDL switch installed, no 7 pin mod.
I replaced the center diff lock actuator. It works great now. But, the transmission relay,the switch that controls the actuator, keeps chattering--clicking off and on, over and over again. I am 110 % certain that is the part that is making the noise. I can feel it, hear it chattering when in gear, at idle, or any RPM.
It does NOT make noise when the CDL is engaged. It also does NOT make noise when the CDL switch is unplugged.
I did troubleshoot the switch by plugging in the hazard switch in its place, and it does make the chattering noise with the hazard switch plugged in, confirming the the switch is not the issue.
I replaced the Transmission relay, and the new one behaves the same.
Has anyone experienced this? I am thinking i might have a short in the system somewhere, but dont know where to start.
Thanks guys, hope someone can shed some light on this, and help me with a starting point.
Thanks,
