A bit more reading on Mopar forums about Sniper upgrades has led me off on a bit of a tangent. Changing to EFI requires a fuel pump that can draw up to 20 Amps. Air conditioning can add about another 15 Amps.
These two upgrades alone can double the original current draw. The easy fix is to upgrade to a newer high output one wire alternator and do away with the original external voltage regulator. This is great but leaves the ammeter in circuit, wired with cable which isn't adequate for the new load and now a fire risk.
Maybe the best solution is to do away with the ammeter and find a period voltmeter to replace it.
Another option if keeping the original charging system would be to fit LED headlamps and wire the air conditioning to disable the heated rear screen when in operation.
