Dexter actuator, P3 Controller issues
For those who have this combination I have some questions.
I posted earlier after test driving in the neighborhood thinking that all was well. After taking a 140 mile trip I have some issues.
If I use aggressive braking with the tow vehicle the Dexter actuator does a nice job under 30 mph of stopping the 25ft classic. If I drive normally the Dexter never activates.
At highway speeds the Dexter never activates unless I get really agressive as well.
I have set the P3 up as usual. I have tried all boost levels nothing seems to change the fact that the inertia system just does not activate fast enough to do anything. I have a spare P3 and have swapped it out no difference.
The Actibrake that was removed worked great for 5 years but started leaking. I think the difference is the lower voltage activation of the actibrake. The Dexter requires 3 volts before it starts running. The interesting thing is when I set up the P3 it needs about 8.3 volts before locking up the brakes. With that setting only 2.2 volts is obtained at the Dexter when the brake pedal is pushed. If I disconnect the blue wire prior to the the pump and measure with a digital meter its 3.2 volts. So it appears that the Dexter loading drops the voltage by one volt. This is also true of the 8.3 volts is 9.3 volts at the blue wire when the manual lever is pulled.
I will call Dexter tomorrow but I was hopping someone with this same combination could give me what experience they have had.
The manual says the best controller is the pendilum style Predator DX2 which would appear to be a step back in time and according to the manual gives me no indication that it would provide enough voltage to activate the pump when the brake pedal is pushed.
I think the key is getting the pump to come on when the brake pedal is pushed.
I sure do miss my actibrake.
