RoadMaster Invisibrake

Are you using the Invisibrake for auxiliary breaking. If so, does it run your battery down to where you have to jump start the car at the end of a trip? Before you ask, I do have the running lights on.

I don't use that brake but my Even brake would run the Enclave battery down. When I switched to the Jeep I had them run a charger wire in the light cable to charge the Jeep as we drove. Never an issue.

That's the whole problem. The Invisibrake is suppose to send a trickle charge to the toad battery activated by the coach running lights.

Sorry Paul I'm not familiar with that system. Can you check for voltage coming into the toad battery?

I ran into another not so happy invisibrake user with the same problems. I'll call Roadmaster in the morning.

You don't say what you are towing. If it is a CRV, I understand that the battery is pretty small and easily run down, we haven't towed ours far enough yet to determine if we will have this problem. We tend to do short days and always carry a jump battery so we may not experience it. I have also read that there is a kit to allow installation of a larger battrry.

My toad is a 2013 Lincoln MKX with a brand new battery three months ago.

I tow my Jeep with the Invisibrake and don't have any problems with it. Just turn on the coach lights when driving. Are you possibly pulling a fuse or something to make the toad towable?

I have the invisibrake setup and tow a Silverado with no problems. My unit does send a small amount of power back to the toad to prevent the battery from dying.

Conceptumater, I don't pull any fuses.
CT Camper, my running lights are on full time driving.
Go figure, 5.5 hours on the road today and the toad started; no problem.

Hmmm....only thing I know to do, then, is to check the wiring and be sure there's a current going to the battery when the lights of the TV are on and it's connected. I usually go 2-3 days without starting the toad when we're headed out to somewhere to stay awhile and never had a problem. Possibly you're got a bad connection where the charging wire ties into the toad light wiring?

Paul,
Are you referring to the running lights on your toad? Mine stay off with the wiring even though my truck had running lights. I have ignition off and keep it in park while towing.

CT, running lights are on the coach in turn the rear lights of the toad are on also. In park? Or neutral?

My Berk has running lights on but never on for toad. Only time rear lights are on are with parking lights and / or brake (exhaust brake included). Let me see if I can find my wiring diagram. I would bet you're drawing more power than the system is putting in. Doesn't make too much sense because I've done a lot of night driving without any battery issues.
