The 20 amp fuse for the Roadmaster InvisiBrake Supplemental Braking System part # RM-8700 could be installed anywhere on the red power wire that goes from the battery to the InvisiBrake controller but if it was installed correctly then it should be 6" away from the positive terminal on the red wire above. I have attached a photo of this for you.

However, with that being said this would not really have an affect on the brake pressure adjustment knob not working correctly. If this is your first time using the system then make sure you pull the knob outward towards you before you turn left or right. This is further explained on page 17 of the owner's manual.

I spoke with Roadmaster and they stated that if you still have issues after you have checked to make sure the knob is pulled outward before adjusting the pressure then it would be best to contact them directly to resolve the issue.
