Resetable circuit breaker

Can I use resetable circuit breakers to replace my fusible links? What amperage?

Those will work. Another Amazon vendor has a two pack for the same price. Keep in mind, the fusible links are not all the same amp rating. The fusible link for the alternator is 60 amps and the other two are somewhere in the 20-30 amp range.

Amazon Amazon

You can also retro fit a send gen RX-7 engine bay fuse block that uses BUSS fuses. This allows you to add additional circuits. The second gen bracket fits really nice with just a little trimming. It's easy to adapt the first gen brown fusible link block. Instead of cutting the wires, I used a hammer to get to the wires. The left the end connectors in place and just plugged into the second gen fuse block.

I have a spare second gen block if you're interested. Hit me up and we can talk about price. It will be cheaper to go with the Amazon ones though.

There are three in that block. The first wiring diagram of the factory wiring section shows these.
