My x300 has no power to the ignition switch. Battery is fully charged and mower will start if i jump the solenoid. I checked all the fuses and safety switches. The ignition switch checks out too. No power at any of the terminals. The fuse block is a little confusing. It has 3 fuses, 15, 20 and 7.5. All are good but when I look at the back of the fuse block it seems like only the 7.5 is wired right. The others only have wire on 1 leg. See pic. If there a fusible link on this mower?

The reason that there is only one wire to those fuses is the heavy red wire in the middle is on a 3 bridge connector that feeds the fuse above and below it. I would pull the fuses to make sure the terminals are not corroded.

I did pull them and clean the terminals. I also switched them around. It ran fine last week. I even pulled the engine cover to make sure mice didn't chew any wires.

Actually there is a connector before the fuse block and also a fuse link of which either one could be the problem. Now if the terminals in the fuse are corroded cleaning doesn't usually work as the fuse block and especially the terminals needs replacing. Wire 202A then proceeds on to another connector and becomes wire 202B before it finally reaches the ignition switch "B" terminal

Here is the area of the schematic (based on the serial number) that shows the wiring up to the fuse block from the battery positive side.

And then on to the ignition switch.


BTW IL the X300 with serial numbers before 040001 has a different setup as to this area of wiring.

Thank you.

I don't see anything resembling a fusible link between the solenoid and the fuse block.

I think I see the wiring problem. The connector with what to be black wires (likely numbered 200C and 200B) is on the wrong starter solenoid main terminal. It is on the starter side and not on the battery side so no battery voltage applied.

I think we have a winner. I was looking at that wondering how the battery voltage was getting to the ignition switch without the solenoid being engaged. The schematic also shows several connections at the main battery terminal. I'll try that in a bit.
Thanks again

That did it.
Thanks again.
