A voltmeter, properly installed, won't burn you car down because it is protected by a fuse. An ammeter can set your car on fire because it has no protection. Also, an ammeter doesn't tell you anything useful because of it's crude scale, while a voltmeter tells you exactly what's going on.

"fact is that properly installed Ampmeters are no more a fire hazard than any other powered wire...like for instance, the heavy gauge, direct Battery connected wire supplying the Ignition Switch...and every car has one of those!"

I'd describe the unprotected heavy gauge wires in old cars as neccessary evils. Your logic is to increase the risk of electrical fire for a completely useless amp gauge. Also, why haven't fitted a fuse to your ignition supply?!? (And your headlights)

I have seen 1st hand what happens when ammeter wiring sets a wiring harness and dashboard on fire in a 40tonne forklift because I had to fix the mess! When a $850,000 machine is down losing thousands of dollars per hour in productivity due to a $20 vanity gauge, it seems fairly rediculous. I can tell you I put a voltmeter in and removed a completely unnecessary source of fire.
