Title: No spark 1 and 4 ***SOLVED***
Post by: ileumi on September 19, 2018, 08:16:35 AM

Hello. Still fighting with cafe racer...

Ok. Finaly I find problem with loss power. Cylinders 1 and 4 are cold.

No spark on them.... What I Know? Ignition coils are fine. When I change control wires to coils, spark losses in 2/3 and 1/4 lives.

Ignition output stage  fine. My friend borrow me another, and problem wont fix.

I read fault digits in motronic, only hall sensor 2 is active but I think that is "ghost".

I test sensors with led-indicator and both of are fine.

So far, so close? Anything hints?

Kiitos etukäteen :)

And +12VDC inputs both of coils, when power is on.

When you blocked each sensor's gap the light shut off?

Yes Laicth, it will shut off. In test I use normal Duspol universal electric tester.

Problem was worn pin in Motronic. That pin feeds ICU.
