Voltage meter

Is there a tool available like the 110 volt meter that will tell if volt's is going through the wire, on 6 volt? I need something that will tell if the wire is live, with out having to use a test light. Thanks
 
An inexpensive Multi-Meter from Harbor Freight will do the job. Just set it on 20 DC volts and it will tell you the voltage.
 
You can buy a current probe that will measure current flow through a wire .It must be used in conjunction with a digital volt meter ,(dvm). It can be used to measure amps or milliamperes .You can check them out at aeswave.com. I’ve seen them on Amazon as well.Great for measuring small amounts of parasitic current draw. Dennis

Current flow (amps) can be read with an inductive type meter as long as there is flow going on. In a DC circuit, there has to be a load for current to flow to it. For voltage, it has to have direct contact somewhere in the circuit with the other end of the meter to ground unless you are reading across a resistor to see the voltage drop of that resistor.
 
I don’t know what the correct term to describe the ability to not have the readout go crazy, and possibly even destroy the instrument, from the electric interference while the engine is running. Usually cheaper units are the ones that can’t handle the interference.

An analog meter can handle the noisy power of a running A. A good quality digital can too. However, most readings can be taken with the motor off, then even a cheapy will be fine.
