stihl 029 coil wiring question

[kkelly311]

Rebuilding an 029 someone gave me. Think I have bad coil. Question on the wiring for them. The wire from the on off switch (from the handle area) connects to the top coil bolt and then the other end to the block and then there is a bridge wire(short with two eye ends) from the same top coil bolt to the block and then the wire that slips on the square tab.... can someone confirm this is how it is supposed to be? If so, have a bad coil .... what aftermarket brands have any of you had success with?

Just unplug the wire at the spade terminal on the coil, then test for spark. The leg of the coil needs to be grounded to the block as well.

Here is a quick pic off the internet. Just unplug that spade terminal and test.
