I have a question about the invisi-brake warning light on the dash of the motorhome. The installation manual leads me to believe that the warning light they mounted should light up everytime you apply the brakes in the motorhome but the installer tells me it is only supposed to come on if the brakes are on in the toad for more than 15 seconds and that an audible warning will also sound. Which is correct?
The LED warning lamp is wired to the cold side of the brake lamp circuit of your towed vehicle, so the lamp should illuminate anytime the brake pedal is depressed. When you step on the motor home brakes, it should illuminate immediately, but will go out after about 15 seconds of continuous braking, even though the motor home brakes are still applied.,
The reason the LED goes out is that the Invisibrake system released the brakes after about 15 seconds. To activate the towed brakes again, you must release the motor home brakes and re-apply them.
If you get the audible alert, the towed vehicle's brake pedal has not released... the LED should also be illuminated. It takes about 20 seconds before the audible alert sounds, so the alarm really is an alarm that the Invisibrake didn't release properly.
If it doesn't work this way, you may need to have diodes wired into the towed vehicle as there is probably a backfeed issue with the towed vehicle wiring.

That's what I thought but the tech that installed it told me otherwise. I am going to contact the manufacture and try to get this explained in writing so I can show them it is supposed to light each time the pedal is depressed. Thanks for confirming what I thought.
