Hello.
i mounted 6 vag (06b905115r) coils on my bmw m50 turbo. built in igniter.
Pin1-12v
Pin2- ecu ground.
Pin3-ignition drive from ecu.
Pin4-ground too engine.
doing an ignition test and i hear the coils click but there are no spark at any of the coils when i have spark plugs too check it.
WHY?
i have rpm and trig 1 and 2 signal. about 180-210 rpm while cranking.
Very thankful for quick response.
With best regards David Henningsson, Henningssonmotorsport.
