Vansco control issue
I have a light system on a motorcycle lift that will not operate properly when plugged into the motorhome. When brakes are applied, the brake lights come on momentarily and the slowly flash. When I plug my tow care into the same plug, the brake lights on the tow car operate properly. The installer of the lift thinks the Vansco system is the culprit. I don't have a clue how to troubleshoot the problem. Any suggestions.
thanks in advance.
Jim

I had a similar problem with the brake lights on my "toad" WRV informed me an isolation relay was needed because the vansco isn't programmed for the additional load. I tapped a relay into the brake light line and got seaparate 12vdc thru the realy to the toad light and it has been fine for 6 years.

The Vansco system can handle 6 amps. You MUST connect the signal wires to the out put side of the rear Vansco unit. I tow a 24 foot car hauler with numerous marker lights and all work just fine. If you connect to the input side you will probably damage a Vansco unit. A relay is a good option, it also needs to be connected to the output side of the rear Vansco. The back feed from a rely will damage the input side of the Vansco.

Good call Wayne! I forgot to mention, I used (and the factory recommended) an isolation diode in series with the relay winding. Matt

The outputs on the Vansco are 6A max self-resetting breaker logic. Sounds like they are resetting after sensing an overload.
Wayne's trick of taking signal to a relay coil off the output side shouldn't overtax the circuit (only adds about 0.15A). Using the output to light the relay coil thereby energizing a separate voltage source to your light package should fix the issue.

TJ- good idea; if you have such a diagram feel free to send it to me in PDF form. Otherwise, I'll put this on my list of things to get around to some day. A good coverage would have 2 separate diagrams, 1st being relay activation off Output from Vansco, 2nd being replacement of failed I/O Vansco circuit (which I've done w/my Driving Lights that didn't work).

Another alternative, that I used instead of the relay approach, is to use LED bulbs which draw much less current.

A quick note. Using LED bulbs solved the problem. Thanks to John
