Invisibrake dead battery

About a year ago I purchased an Invisibrake tow package from Camping world to tow my 2013 Subaru Crosstrek. Since that time I have had several instances of dead batteries during trips. I have returned twice to Camping World to try to correct the problem and have been advised that the system trickle charge is working. I also contacted Roadmaster and received the advice that the Subaru power draw exceeded the trickle charge and to install a 12 volt line. I know I am operating the system correctly with MH running lights on and car ignition switch in correct position. I was drawn to the Invisibrake because of the claim on the product material that you "never will have a dead battery". I feel quite mislead by this and was wondering if other forum members have had a similar experience.

I have the system on my Jeep and have towed it 3 days without ever unhooking or running the Jeep. In fact, I usually forget to turn the coach lights on and I have never run the battery down

We finally took off Invisbrake because we had too many electrical issues with CRV and motor home. We are not the only one with this problem. Lot of info on this site

Have towed a 2010 Corolla about 13,000 miles using Invisibrake with no car battery or starting problems. I do remember to turn on the MH lights most of the time.


There is an inline fuse on the trickle wire near the car battery.

We have been using Invisibrake for about 8 months on a Chevy Traverse. We had a lot of initial issues, but only due to an extremely poor installation by Camping World. After Camping World was unable to figure out what they did wrong, we called Roadmaster and they recommended another shop. We had this other shop look at it, and they re-wired it correctly. We've had no issues since then, and it charges well.

I have also run the battery down on my CRV. It's usually if I tow more than 6 hours. Are you supposed to turn on the coach headlights?

Yes you are supposed to turn on the headlights. It steals a bit of power from that line.

I ran my Edge battery down a couple of times and quite low a few times. I finally ran a battery charge line. No more of those issues. Other issues, yes.

I'm not sure I understand why the headlights should be on. Most, if not all coaches, have daytime running lights that are on when the engine is running.
Since the Charge Line from the MH to the Toad is connected to the Positive side of the battery, what does turning on the headlights have to do with it?

I also was plagued with dead battery issues (even with a charge line installed) on my CRV until I replaced the OEM Lawn Tractor battery with a new Group 24, 900 AH Real battery. Problem solved.

The head/running liggts feed power to the Invisabrake, which in turn provides a trickle charge to the toad battery. I think a separate charge line would be better but that is how they designed the system. We have not towed fo a long distance yet so do not know how well it keeps the toad battery charged. We carry a jump battery anyway so will be prepared if we ever need it.

Is this design for gas rigs or both gas and DP's? Might make sense for gasser I suppose since you don't have the battery power at the rear like the DP.
Never thought of this in my original post.

No reason to NOT have power at the rear on a gasser. If it is not there it is easy enough to add.

The invisibrake charge is minimal. I never measured mine but they said about 2 amps. That is probably in an optimum situation but even at that some vehicles are hungry when in the accessory position. I can hear my front collision radar humming.

The additional charge line should take care of any issues except as noted if you have a bad battery.

Thanks


I contacted Roadmaster and they advised not to take it to another shop. Also advised putting in 12 volt line which seems to me pretty much admitting their "battery will never die" claim isn't true.


thanks
