1 more Ammeter ? Is it switched?!?!?!

[SWEET7T]

Thanks to the previous post, I learned that there are 2 fuses for the ammeter. Both of mine were fried, so I replaced them, and "tada" it works

While my truck is running, it kind of bounces a tiny bit (stays on the charge side), and sometimes it will jump to half way to pegging on the charge side for just a split second. No big deal, I wouldn't think that it would be a smooth movement anyway

But here is my actual problem... Is this thing supposed to always be 'on', or should it be switched?!?!?! I can turn off the key, flip on the lights and it goes a little to the discharge side. So technically, with the key off, there is no charge or drain, but it still seems to me that there would be just a small drain by this gauge always being on. So, should I leave it the way it is, or can I snip a wire and run it through my ignition switch <-- If so, where would I connect the switch (I would think to do it by the junction box next to the battery, on the black fused wire).

Thanks for all the help!!!!!!!!!!!!!

That’s the way they are hooked up.

Amp meters don’t draw any current directly; they measure the amount of magnetic field generated by the flow of current thru the coil in them. So the more current going thru the wire the higher the magnetic field the more the needle moves, and if the field reverses so dose the movement of the needle.

Ahhhh... Learn something new every day. I didn't know that they used magnetic fields, I thought it was an actual complete circuit.

Thanks, now I don't have to worry about my battery going dead.
