How to install an ammeter

Hi to all,

I'm new to this site. I'm working on a 1953 Packard Deluxe Clipper. It has a 327 inline 8 cylinder, 3 speed on the column, overdrive. I restored and rewired the car. The car was a 6v positive ground system. When I rewired the car, I converted it to a 6v negative ground. I changed the leads on the coil and changed the voltage regulator from a 6v positive regulator to a 6v regulator. Also, put in push button switch on the dash instead of started switch on the carburetor. All wiring is to factory specs.

Now, my question is, how can I wire in an ammeter since I do not trust the idiot light even though it seems to be working. I would still to see if the battery is getting charged. I can unhook the battery and the car will stay running. But I think that does not mean the generator and voltage regulator are charging the battery. It may just be putting out enough to keep the engine running. I would install a volt meter but I can't find one that will read below 8v for the 6v system.

2nd question, does anyone know of a 6v tack meter that will work with my setup??

Thanks for any help.

Only sure fire way I know to check battery is charging is to test the voltage at the battery terminals with the car both running and turned off.On a 12v car you should get a reading of about 14v running and 12 ish stopped so this would eqate to 7v and 6v respectivrly on a 6v system.hope this helps.
On the subject of ammeter, any ammeter should work as its measuring current not voltage.I would connect it in the feed from the battery to the main live connection point (fuse box)that way you,ll be able to see whats going in and out of youre battery.

Trouble with an ammeter is that it must be hooked up inline on the main accessory wire, which means running that into the interior. A volt meter, which actually is better telling you the state of your charging system, can be a remote hookup..That is why the car companies went to voltmeters.....I would go with a voltmeter any day
