Ignition system testing . . .

This does not talk about testing the coil itself. It came from the Dolmar 340/420 service manual. This saw had a single piece coil setup.

With the present day single piece coil pointless ignitions . . .

Accurate testing of the ignition module is only possible with sophisticated test equipment.

For this reason it is only necessary to carry out a spark test in the workshop.

A new ignition module must be installed if no ignition spark is obtained (after checking that wiring and stop switch are in good condition).
