Here’s a schematic for the AC system, the 5A fuse is the power supply for the panel/controller. Unplug your AC compressor and check the resistance on the clutch coil. When does the fuse blow specifically?

So I read on another forum that it could be the clutch. So I unplugged it and cleaned it and it still blew. But it blows as soon as you turn the machine on

Take the cover off behind the seat, you’re looking for a red wire with a green stripe. I’ll try attaching file again.
