Nomad final assembly

[55 Rescue Dog]

My research shows that the coil can draw upwards of 20-25 amps. I'm actually using a MSD Blaster coil (no ignition box) with a GM computer-controlled distributor and I'm feeding it from a 25A fuse with 12 gauge wire. Virtually nothing of any significant power on my Nomad goes through the ignition switch. The starter solenoid, IGN power, and ACC power are all switched by 50A relays. The ignition switch itself will be on a 5A fuse.

Don't forget when it comes down to fuses, that the instant pull-in current of a relay is 300-500% higher than the constant hold-in current. A 5A fuse might not be enough, but time delay fuse would handle it though. A fuse is suppose to protect constant current for the wire size is all, not just the device.
