Blowing Fuses upon Connection

So as the title says, I’m blowing fuses once the connection is made in the main fuse holder. I just finished putting everything back together after a long rebuild, also just before this I wired a bilge ( neg to batt - posi to switch then to batt. I’ll check this again but it worked fine).

I read possibly regulator, or positive wire touching negative and grounding out?

What size Fuse? Which Fuse? Is this the inline Fuse on the Positive for the Bilge Pump or the Fuse for the Ebox?

This is the 10amp fuse going to the E box. I tried a bit of trouble shooting last night. Jumped the starter relay no problem there, it looked like there was some corrosion and moisture on it so I changed it using parts from my blaster no change. Going to try regulator swap this morning after I buy more fuses

The only time I got my fuse to pop is when I crossed positive and negative connections on battery. Besides that I dunno but hope that helps

It was grounding out problem solved. Now it starts but can’t rev at all when the throttle is pulled. Any ideas?

Clean your battery connections and grounds. Go through your ebox too. Shorting out somewhere.

He fixed the fuse problem lol
Problem solved it was an exposed wire grounding out. I installed a second cooling line on the exhaust manifold and the cover for the positive starter cable was touching the fitting. After ripping apart the Ebox 3 times that was the issue. Now I’m having rev issues. Idles fine once any throttle is applied it sounds like misfiring or the cdi is stopping it from revving

Only reason a fuse will pop is if something is grounded that shouldn't be
Look for a pinched wire

I see now, skimmed over it. Sounds like CDI if you've torn into it a bunch of times. Cut back plug wires and try again... can test stator once ebox is open again but more than likely cdi is toast

Maybe pull the heat sensor off the head too, if it’s bad then it’ll be in limp mode. I removed mine altogether

So we replaced every component of the e box and still the issue persists. A little back story the skis top end popped 6 weeks ago and have been waiting on parts since, the motor was sitting on my bench I left the carbs on everything else off the block. Is it possible the carb pumps are gummed up from sitting? I never had carb issues prior to cracking the cylinders
