Heya all. Today when starting my ‘95 405 SRDT, the electrical system has completely died. The glow plug light came on and then a moment later, just before starting, everything went dead. The ONLY component in the car that has any power whatsoever is one of the cabin lights (the one activated by the doors). All fuses look good. Battery is fine. Any ideas before I have it towed to my mechanic (or the junk yard!)?? Cheers
