My '77 300D which usually runs great wouldn't start this morning. I tried jump starting it from my wife's car and it still wouldn't start. Electric clock, lights, etc., seem to have normal brightness. Mercedes battery is only a year or so old. Glow plug indicator light on dash does not come on. Also, engine will not crank. Is there a fuse or something I should check or replace?
Many thanks,
Peter Hollings
