W126 Electric bug...
 

Hi guys! My 300 SEL (1988), has an electric problem. Headlights dont work. Have checked fuses and bulbs, all OK. RH indicator works fine, LH one works, but headlights flash at the same time(on brights). It also picks up a miss when the engine warms up. Have checked sparkplugs and have adjusted the gaps. Any ideas guys? Thanks
