I'm in the process of building an AV10, and I just installed the ignition (https://www.treatland.tv/MBK-HPI-CDI-ignition-system-p/mbk-hpi-cdi-ignition-coil.htm). I timed it (3mm BTDC) and got it all wired up according to the instructions (https://www.treatland.tv/v/vspfiles/assets/images/hpi-instructions.jpg), but I can't seem to get it to spark with a drill test. A cursory search through the wiki yielded nothing of use.
The big three prong plug from the stator plate is attached to the CDI box.
The orange cable coming off of the CDI box is plugged onto the blade connector on the coil.
The coil itself is attached to the stock coil mounting points and pretty well grounded to the frame.
The black wire coming out of the CDI box is grounded to the frame via one of the coil bolts.
The kill switch wire is currently not attached to anything, although I tried grounding it and it didn't make a difference.
I am using an NGK TBO5EMA boot and a BR7HS plug. I tried it with the plug grounded to the head and to the coil, and it didn't produce a spark in either configuration.
I feel like I'm missing something obvious here. Any ideas?
