Hello all.

A friend of mine did most of the restoration on my 72 firebird. (I appreciate your comments even though it's not for my ERA Cobra -I feel like this is a safe place!). Bottom line: he did an atrocious job with the wiring and it falls to me to fix it. I don't have a huge amount of experience in wiring but I'm going for it.

A question about size of fusible link and wiring:

Let's say other than the starter motor, my electrical system draws 175 amps with everything on...My alternator is rated 220 amps total and 150 amps at idle.

Let's also say that the starter draws 350 amps when cranking.

What size fusible link do I need? And where do I place the fusible link? Does the starter need to be on a completely separate circuit without a fusible link?

Current set up :
1. Right now I don't have any fusible link
2. Battery is mounted in the trunk, LS3 engine in front with Holley Terminator X Max ECU
3. From the positive terminal on the battery, I run 2' 1/0 awg wire to kill switch mounted on the rear outside panel
4. From the kill switch, I run about 10'-12' of 1/0 awg wire to Starter motor
5. From the Starter motor, I run about 4' of 1/0 awg to the alternator
6. From the kill switch, I have another 1/0 awg wire that runs to a buss bar; from that buss bar, I power a fuse box/relay (fuel pump) in the trunk and another fuse box/relay panel (windows) in the cabin. There are other relays for holley ecu, vintage ac...
7. From the alternator, I run 1/0 awg wire to charging ports in the front lower valance and then to power one more fuse box/relay panel under the hood (2 fans, headlights, horn)

Thanks in advance for any comments or suggestions that you have.

Regards,
Phil
