Honda Ruckus Turns Over But No Spark
2014 Honda Ruckus
was running just fine before I took it apart to add loom to wiring harness and other parts.
Parts already installed when working good:
Rolling wrench EVI
motor has 160 miles
new spark plug
new belt for CVT
battery is cheap and has 70cca?
Parts I added:
TRS intake bracket for airbox delete kit
Valve Block Off
TrailTech TTO Tach & hour Digital Guage
POLINI variator Honda Ruckus Variator 49cc
HMF exhaust
battery tender
Ruck was running fine only with the EVI. I wanted to install the exhaust but in order to do that, I wanted to give it more air. I do want to mention that the end where the plug connects to the spark plug came off. I pushed the wire side in and twisted it clockwise to secure that. I also checked the fuses, all were good. There is fuel in the carb, and fuel pump seems to be working. The engine will turn over fine, I just get no spark when grounding to engine or bolt on frame. I’ve looked everywhere for a possible solution and have no luck. ECU seems to work, the reset with headlight turning on works. Could it be the battery tender? Could it be that I shorted the battery while connected? That caused a spark lol I think it’ll run great if I get it to spark. Please help!

Found the issue. It was the Rolling Wrench EVI. Kept that in place but disconnected from battery, switch and plug. Ran the oem coil to spark plug. Turned the engine over and it gave me a spark when grounding. Threw spark plug back in place and fired up perfectly.
I tried to find out what could’ve been wrong with the EVI, no luck trouble shooting that. If anyone has a link or video on how to check the RW EVI, please reply.
RW EVI was working fine before I decided to upgrade parts. Not sure why it didn’t work this time. I did notice my battery run low within 10 mins of riding it under 10 mph. Wouldn’t electric start after but fired up with a kick. Does this mean I need an oem battery? I currently have the Xtreme AGM XTAX5L-BS, 12V 4.5AH. Google states 70 CCA while the oem is Yuasa YTZ7S with 130 CCA and 6.3 AH. Maybe this is why I’m not getting a good enough spark in the EVI? Any input would be nice.
