Invisibrake not charging tow vehicle.

Dealer installed an Invisibrake. I am towing a 2007 Honda Odyssey following the procedure outlined on this forum. I make sure EVERYTHING is turned off before I tow it.

I repeat the procedure and let the engine run about every 2-3 hours. At the end of the day I have a little trouble getting the engine to turn over. So far haven't had it die completely, but it's getting close.

I have the 2016 F53 chassis. Is there something special I need to be doing to get the tow vehicle battery to charge with the Invisibrake? There is a red wire running to the battery on the Odyssey which I assume is meant to charge it.

With the tail lights on that level of current flow might be enough to drop the voltage enough to prevent adequately charging the battery.

LED tail light bulbs..?

300W DC-AC converter(***) with an inexpensive battery charger.

*** works down to 10.5 volts..

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.

Are you absolutely sure the 12v charge wire from the MH is carrying power to the Invisibrake? It has to get its power from somewhere.
