Question clutch diode??? huh!

ok. I have 03 600. I can't start the bike in gear. only in "n". I pulled out the clutch pin(whatever it is). I checked with ohm. works fine. I checked neutral safety switch. running wire from switch to grnd. no problems. I also put ohm reader on switch to grnd worked fine. It was little flakey. when I just barely touch 2nd gear(moving gear shifter with hand) ohm reader would sound. checked wire. no problems. thinking act replacing "n" switch. bike is an 03. gotta be bit worn out. I followed the book to "almost to a t".

But something did happen. I can't figure it out. I heard something "pop". It was def from the front of the bike. Like behind the black cover(covers all the wires and crap). I didn't see no smoke, smelled nothing melting or anything. Like a fuse or something. I have all electrical working. headlights, horn, tree, starter button, kill switch, signals/switch. Just can't start it in gear. I checked all fuses.

So service manual says check clutch diode (under gas tank). Um, with color coded wires. HUH???? all I see a coil pack where the front two spark plug wires go into. then grnd wires, another set of wires on the back. so where is this clutch diode?

So what gives????

it's under the left side cover near the upper frame. Does the neutral dashboard light stay on continuously?

the "n" light does not stay in continuously. Do Have to unplug all the wire harnesses?

that's odd, usually the neutral light doesn't shut off if it's really the diode. The diode is about Ĺ-inch square, and if memory serves it's taped to the main harness.

it's kinda expensive but you can make a replacement if you like. Number 10 on this page.

if I find it. I can check it with ohm reader to see if it is shot.

if you visited the oem parts link, you'd notice how the diode sprouts out of the main harness. I'm almost sure that it's under electrical tape.

ok. I took all the wire harness apart. I see nothing that looks likes #10 from https://www.hondapartshouse.com/oemp...e/wire-harness.

The heat shrink blue and black is that I put new signals on. So what I am I missing?

Like Ron said, it's the black thingy in this picture. 5/8" x 5/8" x 1/2" square. Plugs into the white connector with either 3 or 4 wires, depending on your bike.
