Got a few PMs asking...one didn't want this to turn into a urination contest...
Oh well, gotta respond before Barney closes this one...
What I meant by properly setup...includes the TV's brake pedal light
switch. Setup so that it turns on BEFORE it moves the MC piston rod
That begets the trailer brake controller to tell the trailer brakes to
turn on...BEFORE the TV's brakes are turned on with a tiny bit of MC
PSI...and...where those who didn't have their after market trailer brake
controllers right...
This will have the trailer brakes lead the TV brakes and how much dialed
in by the pre-set...AKA 'gain'
Many will have a TV brake pedal switch with a plunger actuation and
tough to adjust as finely as GM's brake pedal switch. Normally those
will turn on the brake lights about the same time as it pushes the
MC piston rod...so can NOT lead the trailer brakes...and the reports
or comments of bucking, banging, etc...mine do NOT
Then noodle this:
ALL vehicles sold in the USA that has agency approved braking will have
dual circuit hydraulics...mandated by DOT/NHSTA and has become the
standard world wide
Meaning that there were enough failures in the past to have the regulatory
agency dictate that all vehicles sold for public roads has this dual
hydraulic braking circuit
Which circuit did those BEST in the WORLD MC PSI sensed tap into?
I know neither of them did both...just one circuit. Noodle the
ramifications of that in reference to the historical data that had
the regulatory agency dictate the dual circuit...if that one circuit
went south...then no trailer brakes...
Then noodle or answer me which one does the current ear OEM IBC tap
into?
Just one or does the OEMs tap into both circuits? Don't think both,
as the $$$$ and the overhead both in R&D, production and warranty
would, my guess, say they only tapped into one...
The after market Prodigy does NOT have this potential issue and is
sensed on the TV's brake pedal switch that turns on the brake lights
Again, there is nothing wrong with anyone's choice...as this is a free
country to date...my opinion is stated above and not going to take
the position that it is best for everyone...just for me and those who
ask me to help setup their system...
PS...there is a after market that senses the TV's network via the
inspection port. So assume it senses the TV brake pedal switch and can
be just as good as what I prefer. Or if it senses MC PSI...not much
different than OEM IBC and predict the same route as the old MC sensed
after market products
Plus, this now adds to the complexity of the computer 'highly integrated'
system(s) and the higher potential of issues...to trying to solve a
problem...
