not working, both had problems and not working

After following the installation instructions both ammeters were not working, we installed them on a 1954 body tractor if it helps anyone.

Pros
  • Gauges
Cons
  • Functionality

The best combined volt/ammeter I have ever seen.

Great combination of multimeter! Compact but very informative. Both lines are legible and accurate. Installation is easy if you follow the detailed wiring diagram. The included shunt is reliable.

Pros
  • Electrical
Cons
  • Other Other

A good meter for measuring current in one direction.

The meter worked exactly as described. This is best for a permanent installation, but I was able to use it for a test application. The meter only measures positive current, it measures zero for reverse flow.

Pros
  • Spare parts
Cons
  • Some defects

DON'T BUY IT SHIT!

These are the worst gauges. They measure the voltage is ok but I bought it to measure the current in the power wall. It's so bad you can't trust him at all. You'd better measure the mV drop across the shunt and get a more accurate reading. It has adjustment potentiometers for voltage and current. Again, the current readings are terrible no matter how much you correct.

Pros
  • Automotive
Cons
  • Difficult to say

If you see 0 amps, check your wiring!

I received these and although they showed voltage they showed 0 amps. Reading other reviews I assumed they were just as bad as the others. I ordered several from another seller, hooked them up and encountered the same problem. 0 amps! So this is NOT a counter. It turns out I mixed up the thicker red and black wires measuring the load. Your change resulted in the APPEARANCE of AMPS! MARVELOUS. hahaha So if YOUR meters read 0 amps I suggest rechecking your wiring. Flipping the thicker red/black…

Pros
  • Ammeter
Cons
  • Updates
