I like your suggestion rapid Robert. I've got a similar situation. I've started putting the dash harness in to my 74 Charger. I noticed to red wire lug to the ammeter was cut off. I looked at the engine harness and noticed a 10 gauge red wire from the battery to the one post of the starter relay. On the other post of the relay, there's a red wire (10 gauge) running from the relay through the cowl to be connected to the ammeter, completely bypassing the bulkhead connector block. The only problem is there's no fuse anywhere in it. I was going to hook the original red wire up to the ammeter but after reading several posts on this, I think I'll leave the bypass wire hooked to the ammeter and just install a fuse or fusible link in the red wire bypass. Should it go between the battery and the starter relay or should it go between the relay and the ammeter?
