R33 blowing ignition fuse!

[ChoppedSpots]

Hi guys, 

1994 R33 sedan, engine swapped 25de neo and manual converted.

Yesterday I stalled the car reversing, it wouldn't start back up again straight afterwards. No crank. No lights on dash. No fuel pump nothing. 

Looks like I blew the ignition switch fuse in the back. I bought a new one (30amp) popped it in and when I turned the key I got lights on! However they were very dim, my first thought was that the battery was also flat enough to get some juice but no start, try to crank it but *click*  and no start. ok. 

hook up the battery jumper directly at the back, go to start and nothing. At all. Blew the same fuse. 

I'm not too sure how to proceed further now. Could try the same size fuse but higher amp? jumping the fuse with wire? potential fire if its shorting where?

Any suggestions would be greatly appreciated!!

The fuse protects the wires in that circuit. Clearly one of those wires or a device attached to those wires has a pretty good short to ground. Dig out the multimeter and start looking for ground where there shouldn't be. You will also need the wiring diagram and will likely need to unplug a lot of loom plugs.

I agree, it sounds like a nasty wiring issue. Potentially you drove over something while reversing and damaged the wiring so I'd start by looking at wiring under the car rather than inside

check all your after market wiring if you have something wired to the ignition. get it sorted with a proper fuse or you may risk running a circuit hot and lighting your unit on fire. been there done that not fun...fix it right. i second getting dirty with a multimeter. may be unrelated but check your battery connections, ive had those stupid red connectors on my gtr by the battery get hot and were causing tons of issues on my car. got rid of them and it solved my issues. i think your gunna find a bad connection causing this.
