Is the '40 BATT gauge the same as an amp gauge? The reason I ask is that the needle on my BATT guage rests at the far left (as you face it) of the gauge with the key off. No configuration of hooking it up seems to make it work (show a charge). I have an amp gauge from a 46 that I hook up and the needle rests in the middle and works as it should (slight discharge with key on, showing charging with engine running). Might my 40 gauge be defective, or does it work differently than the 46? Thanks

The 1940 Ford Batt gauge is a volt meter, not an ammeter. Yours sounds like it is working correctly. To see correct operation, see my post in the General Ford Discussion under the topic "understanding ammeter". If you have further questions on this subject, continue this post. Tom

Thanks Tom. I didn't know that the 40's had a voltmeter instead of an ammeter. I know ammeters aren't voltage sensitive. What about the 40 BATT gauge? I'm running 12V in my 40. Thanks

All of the guages may at some point be damaged due to the 12 volts if the guages are still 6 volt.

If you are running 12 volts,your readings will be different than the stock 6 volts. How different will depend upon the method used to drop the voltage to the gauges. A solid state voltage reducer will do a better job than a resister. I prefer to run with 6 volts to make the car more reliable and easier to repair.
