Hi Bruce
The mower is currently up near Taree so I don't have the Model No., I think it may be an LT12. I saw this diagram froma previous post.
https://www.outdoorking-forum.com.au/forum/uploads/284.jpgThe switch in question is labelled No. 10 in this diagram, if that helps at all. I've checked all the switches and they seem to operate as required. The only other problem I could think of is an open circuit inthe wiring harness. Could you tell me what operates the No 10 switch from the diagram, because I think this might be missing from the mower.
Cheers
SC
