I stalled my '03 600 yesterday (only for the 2nd time in 4 months I'm pleased to say) and found that I couldn't start in 1st gear, even with the clutch pulled in. After a lot of faffing around I found it was an issue with a dirty clutch switch so all is now good in that respect.
However, in my investigations I also checked for the diode (as per Haynes I removed tank, unbolted wire harness and displaced) but it's not there, there's nothing "wrapped up in insulating tape". All I could see were the wires for the coils, the fuel gauge sensor and the fuel pump but no diode.
Anyone else have one on a 02/03? Everything's working fine now but I just want to know where it is!!
