Can you be a little more specific. Is that a L240, LT240 or ?
What engine does it have and what year of manufacture ?
Did a lot of searching on the internet for a wiring diagram. Could not find a readable one for free. Lots of manuals for sale.
My suggestion, start following the wire to the PTO clutch from the switch. You can use a push tack to get into the insulation and make contact with the wire inside. I am assuming that you know how to use a volt meter.
Yep, that was pretty much what I found. Thanks for the effort. I don't really mind buying one, but I know I had one. Soon as I do, the guy is gonna call and say he found it.
Meter is not a problem. Got lots of them. Finding where to measure what is the issue. Was hoping to avoid wire following, especially on this model as most of it is pretty much hidden without some disassembly of sheet metal, etc. Troubleshooting these things, solo, can be a PITA, as operator interlocks, switch positions, etc. can cause frustration. Well, it is what it is.
Turns out it is an intermittent problem. I actually got some mowing done yesterday, after replacing the switch. Then it quit. After a bit, not sure how long, it engaged when I tried it, disengaged, backed up to mow a bit more, the, yep, would not engage.
