Designed for high output stereo systems but just as at home on any high current electrical consumer in your vehicle, the AutoMeter Digital Amp Current gauge precisely monitors power along a line using an inductive pickup for safe, accurate measurement of the demand being placed on your electrical system. Rated for up to 250 amps, this gauge is perfect for even the most extreme applications.

I have multiple accessories that I run off an auxiliary battery when my vehicle is off. Can this gauge be wired in a way to monitor overall power draw of these accessories?
As long as the cable coming off the battery to your devices passes through the inductive pickup, our gauge will display current draw.

I recently bought this ammeter, but it is too small to fit in the vent. Do you sell a cup that will hold it in the vent?
Hi, We do have a cup for this gauge, see below. But it obviously has to be larger than the gauge in order for the gauge to fit into it. See attached: https://www.autometer.com/2-mounting-cup-black.html Thanks, Jim

I have recently replaced several batteries and alternators (failed without warning). I have just installed a new high output alternator and will be installing another new battery. Can this ammeter be used to monitor my car's overall charging system?
Hi, Our 6390 Will monitor the output of your alternator, or any DC current up to 250 amps. You will simply route the alternator wire through the inductive probe included with this gauge. Thanks, Jim

Too many old style heavy gauge wire ammeters. When the Cobalt inductive pickup is properly clamped over a wire in the circuit subject to + or - current flow, does the Cobalt amp gauge display the + or - in addition to the digital value? How displayed?
Thank you for your question. No, it will not display the +/- in addition to the displayed digital value.

This amp gauge can handle 250 amps. So, could it be used on the positive battery wire to measure the total current in the entire electrical system in a vehicle? Or perhaps on the alternator charging wire to know the current draw on the alternator?
Thank you for your question. Yes, you could. As long as the lead for you are measuring can fit through the inductive pickup, it will work. You could certainly use it at the battery or alternator as you wanted to, as long as you can fit the wires in the inductive pickup.
