Bypassing the Amp gauge - Question about the MAD Electrical method

I agree about having fuses to protect, that's the last thing I want, to have a electrical fire. I suppose I could run another wire to replace the original red for the ammeter and connect it like the MAD original.
Reread his last paragraph carefully. This isn't about fuses in general, its about a protective device on the battery feed (or feeds).
