No spark problem
Hi,
Recently i bought used BMW R45 from 1981r. Then it worked pretty fine; motor started quite easily, with the new 12V battery. However i wanted to maintenance it a bit: i serviced carburators; new pulling lines; i refreshed wheels and put new tyres. I did not service electrical system.
Now when I assembled it all together - motor started nicely, but after a while it died.
And i cannot start it with a electric starter or kickstarter. The problem is that i'm missing a proper spark at the ignition (When switching killswitch - there's nice spark)
I checked eletrical connections - it all seems fine. I even replaced ICU module.
The coil seems to be fine as the sparks shows up when moving killswitch.
The only time i could start the motor was when i launched it on impulse while pulling whole motor - then values shown on the tachometer were irrational. Even when i turn the bike with the key - tachometer shows about 1K for 1 sec without the motor running.
The only thing i'm not certain about is the hall sensor - but it worked properly in the past.
Can anyone help me solve my problem with the missing spark?
Thanks
