Invisibrake not charging tow vehicle.

Wow there is an incredible amount of issues here. First the Invisbrake does not charge the battery.

Next the charge line does not supply power to the Invisbrake it supplies power to the battery, from which the Invisbrake draws its power.

Roadmaster installed my Invisibrake and wired the charge line into the tail lights. I have to turn on the tail lights to get power to the charge line.

You should be all over Roadmaster management for this – just unbelievable. Tail lights are not a charge line. A charge line starts at the MH battery and ends at the toad battery.

Invisibrake is a load or drain on the toad battery. A charge line is unrelated and it’s what charges the battery.

Most brakes including the Invisbrake draw very little power for the toad battery unless of course you are on the MH brakes a LOT. If there is a significant battery drain while towing with no charge line it is likely a toad related drain.

Thanks CA Traveler, got your PM. I planned on going and purchasing a Voltmeter tomorrow anyway to see if there is a load. Was also thinking of getting a multimeter and seeing what is drawing power at the fuse box.

However, just from what you said, there is a misunderstanding or wrong statement as Roadmaster clearly states that it charges the battery (not via a charge cable either):

• Charges your battery while towing — InvisiBrake connects directly to the towed vehicle’s battery and trickle-charges the battery during towing — InvisiBrake will never drain the battery.

However, I am seeing that it IS draining the battery. I had to stop twice today on a 5 hour drive and both times the engine barely turned over.
