I’ve not messed with it in years. Few challenges are it’s in a dry box in back behind rrp exh manifold. Have to remove engine to get it out. Led hasn’t worked in years on msd. Don’t have Manual I’d have to download it. Paper clip jump sounds like a good place to start in case it’s issue in front cover. Which pins do u jump for Chan 1 and 2. Think it possible just putting a batt charger on it would fry fuse or ign module ?
If your main power (red) was fused odds are you didn’t cook your unit, just popped your 7.5/10A fuse. I’ve accidentally let mine on for a day, charged it on high amp, and never cooked it and ran it for eons after.
You need to pull the 6 wire (2 orange, 2 yellow, 2 brown) connector apart. I believe yellow and brown are channels one and two (you won’t hurt anything by jumping a non used channel). Use a small wire to jump between two of the same color (female pin side).
You’ll obviously want to lay Your plugs out to watch for spark and have the ign on.
Another easy check is to unplug the kill switch side of your stop/start. I forget if it’s the black or white connector but you’ll be able to crank the motor still and if you have spark with it dissconnected you’ve found your issue.
I had that problem a few times from water intrusion in my plugs. Good luck!
I also have a printed manual I can send you pics of if you’d like
