Just inherited a Roadmaster BrakePro (Serial Number 015297)...not sure how old it is. When I plugged it in to the lighter, the compressor started and the cylinder ram compressed fully. The compressor kept running and did not shut off. I decided that probably wasn't right
!....so I opened up the bottom and pulled out the mechanism. I found 2 wires hanging loose with just bare wire ends and no sign of where they should terminate. These wires are junctioned to 4 wires that are attached however on the other ends. 2 come out of the bottom of the circuit board and 2 come are attached to a couple of the indicator lights. I hope this is clear enough. I borrowed a friends unit to compare but his is about 1200 numbers newer and it is different. His circuit board has 6 wires originating and mine only has 5, so I am presuming some updates were made. Anyway, I am looking for someone that may have one like mine and we can work together to figure out where my wiring should go. Roadmaster will not give me any help at all unless I want to trade it in on their newer Even Brake. Thanks for any help you can offer.
