 Post subject: Ruckus won't start after CDI install
PostPosted: Sun Jan 15, 2017 10:59 am 
I followed the directions shown here to install my NCY CDI: http://totalruckus.com/phpBB3/viewtopic.php?f=34&t=72539 and my ruckus will not start when it is plugged in. I can jump the wire that is cut at the ECU through the orange and yellow wires that connect it and kick start it, but I still have no power when the engine isn't running. The two relays will click and that's it. When the CDI is installed, not even kickstarting it will solve the issue.

I realized that I had the orange and yellow wires swapped when I first soldered them and then promptly fixed them, so hopefully that didn't cause any serious issues.

I tried resetting the ECU, but I couldn't tell if it worked because I'm hardly getting power to anything. I've been keeping the battery on a tender so it should be charged.

What do you guys think?

Check your fuses, especially the red 10 amp. Could have blown a fuse when the wires were swapped, or sometimes soldering can heat a wire enough to blow the fuse.

Fuses are checked. All of them seemed alright. When I bypass the CDI and kick start it, all of my functions work. Although I do get the dimming and whatnot when the engine is in low RPM.

The only connection I didn't check was the one you tap into that goes to the relays. I wonder if it's possible that the CDI is just constantly pulling power. I tapped into the same wire that was used on the install instructions, so I'm not completely convinced that's what it is. I'm half inclined to undo that solder connection and see if it makes it any better. I'm looking into getting a volt meter.

Looking at the power connection, it is wired to the ignition switch at the main relay. Does that seem correct?

Also looking at the wiring diagram, these wires go to the blue relay at the fuse box. Could that be blown? How would I go about checking that?

Use a multimeter. See if you are getting juice across the various bits you are talking about.

Check the voltage drop on the battery.

I'm going to buy a voltmeter and see what happens.

My battery tender has a voltage reader on it and the battery never went above 10 volts.

If that right you got a bad battery and that should fix it. You can try to use jumper cables or a high capacity charger. If you get a meter check the volts while attempting to start. If it drops off it won't start.

I made a couple of videos that I'm trying to upload so you guys can see exactly what's happening, and after watching them I'm almost convinced it's the battery. When the pump clicks, the lights flicker. When I hold the brake in, the speedo dims. All the lights brighten up once it's running.

photo bucket seems to have taken a dump on me so I'm going to try to upload these videos via Google drive.

What about the wiring specifically? The orange and yellow wires are spliced into the one on the first thread I posted. The red wire was tapped into the red wire on that thread as well. So if that worked for them, it should work for me, right?

Went ahead and did a parasite test. What do you think?
