Have a 445 with no spark to the plugs. I read a lot about a spark delay module but I cannot locate it on this model. The parts catalog does list on for a 445. Do all 445 have this module? Or do I need ignition module?

There is a s/n break at 70000. Are you above or below that?

More info about the reasons for your suspicions so far would help. (beyond "no spark" )

AM128906 is the common time delay module. If you have it, it is near the left rear corner of the engine shroud. Earlier ones were more square.

it above 7000 on serial number, I do not believe it has a delay module.

Am assuming that number is not 7000 and yours is above the break of 70000.

Here is the troubleshooting table for no-spark. And the "Power Circuit Operation" for perusal.

so above 70000 no ignition delay module?

Adding the Ignition Circuit Operation for the over 70000 s/n that may give some pointers to what might be involved.. also some basic stuff like the PTO switch off. You can decide if the ignition delay module exists.. or if the delay is handled another way (I am not sure).
