However, all of your wiring passes through your ammeter-that makes it the
single most vulnerable point in your electrical system. Years ago my Singer
Gazelle was stopped dead in it's tracks when the connector on the ammeter
broke off. That isn't the case with a voltmeter.

Volt meters go in parallel and ammeters go in series. That means all of the
current (60+ A) could go through the wiring to the ammeter. Very little
current goes through the volt meter (because of its large internal
resistance). That's about it for safety.
I wired my ammeter because the DPO had it wrong. As long as you use wire
capable of carrying the max current your battery and alternator put out
(i.e. don't let the smoke out of the wires!), you should be fine.

Subject: volt meter
Hi gents and ladies:
Has anyone put a volt meter in their car v. an ammeter? My cousin who
is rewiring said it is simpler, safer and does the same job. Thoughts?
Thanks,
Bill
