So I've been blowing battery fuses on my 93 lude with h22a. It only happens when I drive it really hard. I went drag racing on Friday night and my second run I shifted to second, and I shifted pretty hard and floored it right away, it sputtered really bad and had no pull at all, so I pulled it out of gear and coasted a little bit, but it was still running so I put it in third and drove off. When I shut it off it wouldn't start again, it had blown the battery fuse. This was the 2nd time it happened.

I changed the fuse since a brought a few extras with me and thought it was my alternator putting out too much voltage, so I unplugged that and ran again, had a few good passes.

I decided to do my first burnout of the night and was like 3-4 seconds into it with no problems when sure enough it died and I blew my fuse again. But I still had the alternator unplugged.

I can still drive just fine and hit vtec and all, but it seems when I beat on it I'm going to blow the battery fuse, so I'm just looking for ideas of what it could be from anyone. Thanks for reading

check your alternator, it could be over chargeing and blowing fuses.

 

did u swap the motor in or was it already in..if it was swapped make sure there isnt any lose wiring..ive also seen the starter short out and do the same thing but it seems more like a wiring issue
