Does the Suzie blow a fuse when in use? If not then I'd suggest you open up the plug used to connect the Suzie to the motorhome. I've seen some 7 pin round plugs shorting out on the screws which hold the wires in place to the metal body of the plug, or could be a stray wire in there?
G'day Bowser,
There used to be a master/slave unit that was used to connect trailers - basically a set of relays but I haven't seen any of recent years. I made one when I had voltage troubles with our camper.
Assuming both the motorhome & the car's blinkers operate ok separate of one another, I agree with Treecrest - there may be a stranded wire that has one strand not clamped by the screw but touching somewhere that it shouldn't. Check both ends of the cable ie the plug that goes into the MH and where it plugs into the car.
