Ok guys I need help with my 4g64 with some electrical problems I have a main wire that keeps blowing a 30amp fuse that's run from the battery n it's melting the fuseable link holder now I wanna run a circuit breaker 2 it but idk wut amp 2 run I think a 250 is 2 much but @ the same time It is a main wire so if that fuse or breaker blows everything in the car shuts down if someone can give me there advise I will be more then grateful thanks guys

 

If it is blowing the 30 amp fuse, you need to figure out what is causing it to blow. One way to check why it is blowing is to find the circuits that are on that 30 amp circuit and pull the fuses and put them in one by one. Hopefully you will find which one is causing the fuse to blow and can correct the issue.

 

Well that wire was the main wire for the car the 30 blew n everything in the car went dead as if the was not battery in the car those wires go 2 those glass top max fuse 2 go 2 a 40 max glass top n 2 go 2 a 100 max glass top the main goes 2 the 40 I put the wires stright off the battery n they seem 2 be fine not getting hot or anything
