Emergency flash

[FMO]

hi!

I have a strange failure. My emergency flash will only work when engine is running. At once I turn off the engine, emergency flash stop working.
As I understand reading the electric diagram, the Red/Black wire at the emergency switch has to be hot all the time. On my car it is not :-(. No wires at the switch are hot, when the ignition switch is off.

I tried to put a wire directly from the battery to the Red/black wire at the emergency switch. Then it works great even when the engine is switched off, the only drawback is , that the fuel pump also start to run!!!!Strange.

Any suggestions from pelican people?

After several hours, I finally discovered the failure.
Prevoius owner has put the " hot " wire from emergency switch to the fuel pump fuse. Fuel pump fuse is only "hot" when car is running. So I just put the wire from emergency switch to a hot fuse, and voila everything is working :-)

Ready for a beer now :-)
