Hello, I need some help on an old mower of mine and am seeking information to help figure it out. I have a simplicity landlord Dlx with the 17hp Kawasaki motor. I have no spark. I am not very good with electrical and have been seeking help from my cousin who is pretty good mechanic. He first questioned the ignitor on the mower but then he didn't think any power was getting to the ignitor. Then secondly he questioned what looks to be called the module interlock which does have a little melting damage to it. Backstory is I accidentally hooked up new batteries backwards and when mower wouldn't do anything I jumped starter relay to turn it over before I realized what I did. He looked over all the other safety switches and coils and thought everything looked good with multimeter but those were his two question marks. Don't know how to test this module interlock or if that would prevent power to ignitor in some way. other than that I did find the test online for the ignitor and haven't done that yet but it does look to be a fairly expensive part. if anyone could help me out I would greatly appreciate.
