Wiring--a little confusion.

It seems to me that when hooking up the generator for charging the battery, the wire goes from the Generator to the Ampmeter, and from the ampmeter to GROUND on this positive ground system on an H. Have I got that correct?

The supply side of the ammeter usually has but one wire, the hot battery voltage as described above, while its other load terminal wires to BAT on the VR or Cutout Relay PLUS feeds hot battery voltage to lights n ignition.

Since the ammeters supply terminal is wired to the hot ungrounded battery post, while its load terminal receives the gennys output plus has lights n ignition wired to it, it registers the net charging current into the battery or discharging current out of it.

Hope this helps

One side of the ammeter should connect to the ungrounded battery terminal, in this case the negative terminal. The other side should connect to the battery terminal of the voltage regulator (or to the battery side of the cutout relay if that's what you have), and to all the various loads (lights & ignition).

Turn on the lights with the engine not running. The ammeter should show a discharge. If it indicates charge, simply swap the connections to the terminals on the back of the ammeter.

Generator to ammeter to ground sounds like a short circuit. HAve you had a look at Bob M's wiring diagrams ? Cut and paste this into your browser ->Link

A battery is the same and all works as the DC voltage is BETWEEN the 2 batery posts REGARDLESS which post you tie to a huge hunk of iron and use the iron as the return current path versus havin to run 2 wires to everything.
