Hey QldKev, what part of it looks wrong? Heres the link I got it from http://www.ebay.com.au/itm/141094274381?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649#ht_5528wt_984 There are pictures at the bottom. After your comment I have looked at other meters similiar and one shows the coil connected to the screw down terminals and the power connected to the red/black plug. Both of them have shown them working....QldKev said:Looks good.
I would talk to your sparky about the wiring on that volt/amp meter, looks wrong.

And heres a link to a similiar one from the same seller connected up and working, http://www.ebay.com.au/itm/New-AC-LCD-Panel-Digital-Ammeter-Volt-Meter-Amp-Voltmeter-100A-80V-300V-DIY/141094273034?rt=nc&_trksid=p2047675.m1851&_trkparms=aid%3D222002%26algo%3DSIC.FIT%26ao%3D1%26asc%3D261%26meid%3D3491713439255334731%26pid%3D100005%26prg%3D1088%26rk%3D1%26rkt%3D5%26sd%3D131024109025%26#ht_5342wt_980
Advice?
Ah Gotcha, its easy enough to put a jumper around it.OzPaleAle said:Hey Dan, I suspect the issue is with the indicator (power on light) being inline(in series) with the voltage meter instead of in parallel.
Normally a voltmeter is used in parallel with the thing being tested so having something else in series may effect the reading\operation of the module.
The inductor looks like its on the active from the mains supply which should be correct.
I know what your saying QldKev, I will have a closer look at the circuit board and see if there is anything identifying it further.QldKev said:That first link is how mine is wired up. Seeing the wiring diagram of the one you have purchased, it looks like the Chinese producer has made them backwards to each other?
Now we know the difference, you can actually see in the pic the arrangement of the resistors and caps are arranged opposite to each other. So the opposite power and current connections looks correct. Your electrician will check it before he connects it up.vanoontour said:I know what your saying QldKev, I will have a closer look at the circuit board and see if there is anything identifying it further.
Bet it doesn't!! Current rating and indicating capacity are two very different and separate things (as I suspect you are aware of given your signature block). You are correct, there is nothing at all on the amp meter board that could handle 100 amps. But as a gauge to indicate it is fine. And if you can see anything wrong then please speak up as this is what the whole thread/forums are for. Not for cryptic guess work.Glot said:Bet it goes bang. Stop and think. The max current rating of the amp meter is 100 amps. Do those terminals look like they are rated for 100 amps? Nope. You should have a current transformer that actually connects to those terminals and one of the current carrying conductors goes through the transformer ( the small brown coil thing with two wires off it). Some of these meters have one built onto the board and some have a separate one. I cannot actually say that as a definite without seeing it but just making you aware of a possibility of it being wrong.
These home made set ups are scary. I can see a number of safety issues.
