On our 2002 Mitsibushi Challenger 4WD the turn indicator flashers and Emergency Flashers have worked fine. There is a 10A fuse in the Emergency Flasher circuit.
We have a 18 foot Crusader van with a 7 pin connector plug. Each time we hook our van to the car we do a
check that the turn indicator lights and break lights at the rear of the van are working. Normally I
check each turn indicator light and find it is OK.
A couple times in the last year I have used the Emergency flasher switch on the car to
check both flashers are operating at the same time. Each time I have found within a few days that the 10A fuse for the Emergency flasher in the Challenger has blown and has to be replaced.
My first inclination is to simply use a bigger fuse in the car Emergency Flasher but wonder if this is the most sensible to do.
Can you suggest what tests I can do to simplify identify the cause of the problem. The van is currently in storage and not connected to the car. The van manufacturer is unable to supply a wiring diagram for the van.

Have a slightly similar issue to this with the Landrover. I don't blow fuses, but the Landrover has an indicator light on the dash that is supposed to flash with your indicators when you have a trailer connected - purpose is to let you know that the trailer lights are working. Because I've had a bullbar added which has indicator lights included, the "trailer" indicator light now flashes with the indicators all the time, whether there is a trailer connected or not.
The issues here are identical - too many globes for the original wiring circuit of the vehicle. Your caravan with its extra lights is probably OK when only the indicators are working one side at a time, but with the
hazard lights on and all the indicators flashing together, it's simply too much load on the circuit.
The solution is also simple - change some of your indicators, preferably those on the caravan, from filament globes to LED's. They pull a fraction of the power and will reduce the load on the circuit to the point that the problem no longer exists.

New fuse is cheaper ;-))

No doubt.
But then I've never believed in increasing the fuse rating above what was originally installed. Mistubishi installed a 10a fuse here for a reason.
