Risks of Running High Amp Alternator?

The problem is not only the bulkhead connector terminals, but the ammeter itself

One of my favorite examples is an electric furnace and the internal interconnecting wiring. These almost universally use 1/4" flag push on terminals.......the very same type terminal used in the bulkhead connector. Electric furnace elements are pretty much standard at 5000 watts per element. At 220V that is 5000/220=23amp nominal. So every single flag terminal in that furnace has to put up with about 20-25amps, AND THEY FAIL OCCASIONALLY

So if those fail with no more than 20A current, imagine when you double, triple, or quadruple that current
