Replaced the solenoid on my reversing valve on the trailer and still not working. Tested new solenoid and yes plunger is pulling in. I did remove the solenoid off the the new valve and install on old valve. Are they paired up at MFG ? Air in system maybe or maybe dirty orifice on old valve? Any suggestions?

I have never had any luck with my Loadmaster bypassing the solenoid, wish I could help you.

Thanks I'm going to figure this out one way or another. It worked great for quite awhile. Then I replaced all the brake components all the way to the coupler an bam quit working. But the brakes work real good.

Sometimes too good! Good luck

I installed one as well when I changed to disc brakes and it worked for a couple years just fine. Then one day, no more. I played with it but coulodn't get t to work. Breaks also work great though.
