RoadMaster Even Brake Test Pumps Brake Pedal Twice then Fails

Question:

I’ve used th3 3v3n brake unit for a few years now with no issues. This time out I set it all up as usual and when I pushed the test test button the brake cycled 2 times and went into trouble. Failed test. I tried several times with sam3 result. Any suggestions where I should look ?

I spoke with my contact over at Roadmaster and have some things that you can check. When the Even Brake # RM-9400 pushes on the brake pedal 3 times what it is doing is making sure that it is receiving a brake signal from the cold side of the brake switch. If it does not detect the signal then it does exactly what you have described.

The brake signal it is looking for goes through terminal 1 on the Even Brake. What I would first check is that this circuit has 12 volts when the brakes are applied. If not typically it's the third brake light fuse on the vehicle that has failed and caused the problem.
