Hi
Bought a 5v lcd metre off here years ago and I think I'll have ago at fitting it tomorrow, I'm just a little confused why it has 4 wires.
1x 5v
1x gnd
1x signal -
1x signal +
Where do the signal wires go ?
Thanks

Wire signal + and 5v to JAMMA 5v
Wires signal - and GND to JAMMA GND
The 5v and GND are power for the voltmeter. The signal wires allow you to measure voltages other than 5v but in your case you are also measuring 5v.
