Question:

I have read that, if I flat tow a Cherokee that I need to have the battery charging while towing or else it will be drained and then the transmission will go out of neutral. If that is so, will this brake system be what is needed to charge the battery during towing?

Expert Reply:

Yes the Roadmaster InvisiBrake Supplemental Braking System Item # RM-8700 will connect directly to your towed vehicle's battery and charge it while driving unlike most braking systems that would actually drain your battery.

Some notes to consider on this product are:
This product does not work on vehicles with a non-electric hydroboost braking system.

When using TrailerMate wiring with the InvisiBrake, it will be necessary to purchase an additonal two diodes, ( item # RM-792 - sold separately), to prevent the towed vehicle's brake signal from back-feeding into the InvisiBrake system and activating it when attempting to drive the vehicle.
