Battery Wire Fuse Rating?

[CameronBNR32]

I've rewired the battery terminals after going to a smaller dry cell battery, and I keep popping a fuse.

This wire goes from the battery and up into the main fuse box in the engine bay, now it had a fairly large fuse wire inline (pictured below) so I wasn't 100% sure on what rating it was as it has no markings on it, and couldn't fine any info in the manual....

when it pops, the alternator stops charging, dash lights go off, tacho, speedo, radio, climate control unit, centre gauges and probably a few others that I havn't notice.

Car is a 1990 R32 GTR with afew electrical devices taken out, radio, centre gauges, and air con unit, so it would be pulling less current now as it would of seen factory

So far it keeps blowing 50a and 60a fuses.... would it be as high as 100-120A?? anyone rewired their battery wires/relocated battery and had this drama?

the alternator is about 100-120A, so you would want an equal sized fuse.
