Yes, the second generation bikes (1996 & up) all have the same wiring harness.

Keepin' all the left over parts. Gonna use 'em to build another bike!

he's asking because the wiring diagram presented is for 1st gen - it's easy enough to search for a 2nd gen wiring diagram - give it a try @MasterErikis

My mistake; I thought it was for the 2nd gen rebels. Here's the correct diagram: http://www.hondarebelforum.com/f80/h...d-up-5644.html

Sweet, took a bit to find a decent resolution copy of that picture, I kept finding the 300x300something, uhg.
Printing...
Alright I can read it!
Thank you I kept finding the 1st gen wiring diagram or low resolution.

Added notes:
Ignition coils both ground with 1.8Ohm
Ignition coils both connect back to the CDI on the Bl/Y wire with 1.9Ohm

It's raining the next 7 days. Inside and out since my ride isn't starting.
Check fuse box next?

The Rebel ignition system has nothing to do with fuses or the 12 volt system. It is powered by a single coil in the stator on the Black/red wire. This is an AC power source not 12 volt DC.
The ignition module is normally disabled by grounding the black/white wire on the module. This is done by a set of contacts in the ignition switch (when switched OFF) and also by the engine stop switch on the handlebar. The ignition switch does not switch power to the module.

The Green/white wire MUST be grounded either through the sidestand switch or the neutral switch in order for the ignition module to work.

Good luck!

Hey the fuse block was suggested to me!
I have the ignition system paper in front of me that states:
Exciter coil: Black/Red-Green: 270-340 Ohm
And mine measures 135 Ohm, would that cause a problem?
Yes, I checked the Black/White wire to the Green to verify continuity (when the ignition switch is ON and the engine stop switch is RUN), it hit 0.00 but I can triple check that later today.
I will reconnect the sidestand switch or just ground it today and double check the Green/White to ground. I guess I assumed because the kickstand switch worked off the bike it would work on the bike.

I brought the coils into work, they each register as .5 Ohm

The Black/white wire should have no continuity to ground if you want the ignition module to make a spark. It should show as an open circuit to the green ground wire. Switching the ignition switch to OFF should ground the black/ white wire and disable the ignition module.

Since I have a 1999 Rebel like yours, and I knew that there were a few switch settings that would allow the starter to engage, but not allow the bike to run, i.e. NO SPARK, and since I am not sure if you have completely ruled out switch problems as the culprit, i decided to document all the switch settings and accompanying operation on my Rebel.

If the kill switch is in the run position and operating correctly, there are no other switch positions that both allow the starter to operate and prevent the bike from running. There are several combinations that will prevent the starter from operating as well as prevent the bike from running, but if the kill switch is on and the starter turns, the bike should crank and run.

However if the kill switch is OFF, the bike will not run, i.e. NO SPARK, regardless of other switch positions. However there are a few combinations that will allow the starter to operate, even though the bike won't run.

If the bike is in NEUTRAL, the starter will operate regardless of whether the clutch is IN or OUT, or the kickstand is UP or DOWN, but the bike will not start with the kill switch OFF.

Also, if the bike is in gear 1-5, and both the clutch is IN, and the kickstand is UP, the starter will also turn, but the bike will not crank when the kill switch is OFF. The starter will not turn if either the clutch is OUT, or the kickstand is DOWN, when the bike is in gear.

Therefore, unless you have 2 switches that have both gone bad at the same time, the only switch that can malfunction by itself and cause your problem is the kill switch, if you have all the other switches set correctly.

Try cranking the bike with it in NEUTRAL, and the clutch IN, and the kickstand UP. The starter should operate regardless of the setting of the kill switch, but only have SPARK with the kill switch set to RUN.

If that doesn't get you SPARK, then in order to completely eliminate the OFF function from all switches, and therefore rule out any switches as the culprit, just temporarily disconnect the black/white wire from the ignition control module (CDI). This takes away the possibility of grounding the ignition, and it should have SPARK and RUN regardless of the switch settings if the starter will crank the engine.

If it will now SPARK, the problem is in the switches. If not, then the problem is in the ignition system itself, and the switches have nothing to do with it, and can be ruled out.

A note of warning though if you do this, all of the safety switches will be disengaged, and neither the ignition or kill switch will shut the bike down. You will have to choke it down to stop the engine. This is just for testing, and you should reconnect the wiring after you find and repair the problem.
