Volts & amps in one

[threedogs]

Heres a little ripper , not sure how many are fans of amp meters,?
Might be interesting to see what devices pull what amps when working.
Price is cheap compared to others out there

Think Ill change my Aux battery volt gauge to one

Dunno about accuracy, but good as quick reference.

Not sure why? this will only measure upto a 10amp load? so no good for measuring Alternator charge. if you have more than a couple of things coming off your aux battery and the draw gets to 10amps this will stop working? anything your running a 30amp relay off will not function with this either?

I would actually be interesting to wire it into the Fridge plug directly assuming it will read the Fridge Draw? not sure how you would stop it reading all draw off a circuit though? maybe it would need to be a switched circuit from Battery to Fridge only? it must then differentiate between input and draw while driving? I think it has a limited application.

Id be interested in measuring and monitoring Alternator Output in Amps?? and or Winch Draw in Amps?? Very interested in that.

Very easy to set up a high current shunt and use connect an ammeter across it, for the winch.

Example only http://www.ebay.com.au/itm/Amp-Ammet...0AAOSw5ZBWIIo7

In layman's terms: The ammeter is only a very sensitive voltmeter, that measures the voltage drop created by the current running through the shunt.

Or a matched set, for reference purposes only while setting up the circuit as it ain't water and muck proof.
