I removed the extension cable from the Zeel unit and had the same results.Are either of you running the ribbon cable extension? I've seen several extensions fail.
Ya it really is. It’s gotta be in the +5v voltage regulation circuit. I’d imagine the CDI circuit is independent and the IC that is the “brain” of the unit can be powered by the programmer or a 5v circuit powered by the battery and that’s why it works when plugged into The programmer.Such a weird way for it to fail.
That makes perfect sense. Probably could even make it work with an external 5v power supply to the right pin on the ribbon cable. Wouldn't really want to do that though.Ya it really is. It’s gotta be in the +5v voltage regulation circuit. I’d imagine the CDI circuit is independent and the IC that is the “brain” of the unit can be powered over USB or a 5v circuit powered by the battery and that’s why it works when plugged into USB.
I did some “digging” in mine lol. Where it had the hole in the potting looks like it could be a “linear voltage regulator” with a heat sink. So makes sense that if that burned up it would have these results like you explained. Not sure how to test it but maybe I’ll try to replace it…Ya it really is.

Have one for the 4pin 62t version?Zeel port pin-out. View attachment 425841
Is it possible you had the lanyard hooked on all winter? I think the zeel stays powered if the lanyard is hooked up and that would certainly shorten that regulators life.Got the new unit from JetManiac today. Put her in and she's perfect now. It was absolutely the Zeel unit.
I very likely had the lanyard (surf switch) engaged and usually do from clearing it out on the trailer. I can’t remember if I had the battery ground hooked up after Daytona, but it might of been.Is it possible you had the lanyard hooked on all winter?

This is interesting watching this. I hope you get it sortedI very likely had the lanyard (surf switch) engaged and usually do from clearing it out on the trailer. I can’t remember if I had the battery ground hooked up after Daytona, but it might of been.
I cleared out more potting- I’m getting 5v on pin 4 without the programmer hooked up. The part I suspected was a linear regulator is a mosfet. It has power to it and ground at one terminal. Nothing at the other but idk what it turns on, guessing it fires the coil?
I suppose it’s possible that it’s working again after scraping around in it too.
One thing I had noticed while it was still in the ski is if I unplugged the programmer it would still have spark if you crank the ski for around the next 30seconds time. Longer than that and it wouldn’t spark. View attachment 425944Like the programmer maybe wakes it up, but it won’t wake up on its own.
Nope no lanyard. I also take my AG battery out after every ride and did the same before I put it in storage for winter. No power was going to the unit for about 4 months.Is it possible you had the lanyard hooked on all winter?
