Tändningskontroll (ignition check) på Svartqvarna

Fråga: Hi. I have a. Svartqvarna mod24. How can I set contact points? How can I check coil and condenser?

The motorbike has become hard to start. The spark is intermittent. Your help would be appreciated.

Thanks

Edward

 

Svar: The contact points (brytarkontakter) should have a gap of 0,30 – 0,40 mm on ignition systems with a serial number lower than 26000. On systems with a higher number the gap should be set to 0,35 – 0,45 mm. But start with cleaning the points with some brake cleaner (Bräkleen).

To test the capacitor (kondensator) you first has to disconnect it from all cables. Than you charge (laddar) it with a 12-voltt battery which take a fraction af a second. Then wait for a minute and short the capacitor with a knife or a screwdriver. If the capacitor is okey you should be able to see and hear a little spark when doing that. Otherwise – use a multimeter to see if the charge is still there after a few minutes.

The ignition coil (tändspole) would be tested in a special tester for ignition coils. And the coil should be pre heated to circa 70 degrees celsius (160 Fahrenheit) prior to the test.
