Need an Adult. Alternator Wiring Question. Non-OEM System
Hey Guys,
I'm an idiot. I need someone to hold my hand with a very easy wiring question regarding fusing an alternator to a firewall bulkhead. It's literally the last thing I need to do on my car before it hits the road.
Key Details:
- 72' Scamp. The entire wiring harness was replaced with a modern EZ kit. Nothing is original.
- I have a 1 wire Powermaster alternator that generates a max 100amps.
- Battery is mounted in the trunk. 2AWG wire runs though the cab to a bulkhead at the firewall. In the engine compartment, this bulkhead feeds the starter relay and the starter. Bulkhead is circled in red in the photo below.
-Behind the firewall is a relay board that powers my accessories. Everything on this board has its own relay and is individually fused. This relay board is powered by the cab-side of the bulkhead bolt.
- I have an inline MAXI fuse from the starter relay to the EZ fuseblock. This is circled in blue in the photo below
- I will be using a 4-post master disconnect switch in the rear. Not sure if this is relevant, but wanted to mention it.
So here's my question...I need to run a 2.5ft charging wire from the alternator to the bulkhead bolt that goes to the battery. Does this 2.5ft wire need to be fused? If yes, should the fuse placement be somewhere in the engine bay or in the trunk near the battery and switch?
Thanks in advance
Jim
