So I have a ton of these multi-wire connectors and I've been using
them in various ways to connect components together and distribute
power. Are there potential issues in combining the wires together
(positive together and negative together (see attached)? I ask because
it suddenly hit me that perhaps the multiple wires were increasing
voltage or signal (i.e. if I had two sets of positive and negative
wires going into a component is it receiving double the power) or
creating problems in amperage.

I ask because I've been having problems with increased voltage or
reversed polarity when I measure with my meter.

Thanks,

D. Scott

Aeroelectric Connection sells the best book you'll find regarding all wiring and connectionAbout $20 but they also have downloadable articles just browse around you'll get educated

And while the previous Aeroelectric Connection site I mention has correct method examples for Aerospace application (and therefore also our hobby robotics may easily hold the same standards)
the following is an entertaining compilation of electronic hobbyist DIY that I would reason a guess does not follow any specific example however none the less is perhaps a lesson in not what to do.

Re: Opinion on Connectors [1 Attachment]

You can run one wire or 12 wires between a power source and a load (bulb) and it will never be higher than what you started with at your power supply. 12 wires (assuming all the same diameter) will just be able to handle 12x the current.
If you run power to some device, be it a bulb, an amplifier, or a motor, run the ground from the same power supply.
The NEC police won't lock you up for this, but it's a good idea to stick with standard color codes when using these connectors. Black for ground, red for 5 volts, yellow for 12 volts. That way you never get confused as to what voltage is on a particular connector.
For computer components, it's very common to have a red, yellow, and two black wires for 5V, 12V, and ground on the same connector. This is typical for hard drives.
In the very least, stick with labeling them like you did.

So I have a ton of these multi-wire connectors and I've been using
them in various ways to connect components together and distribute
power. Are there potential issues in combining the wires together
(positive together and negative together (see attached)? I ask because
it suddenly hit me that perhaps the multiple wires were increasing
voltage or signal (i.e. if I had two sets of positive and negative
wires going into a component is it receiving double the power) or
creating problems in amperage.

I ask because I've been having problems with increased voltage or
reversed polarity when I measure with my meter.

Thanks,

D. Scott

Not to worry Daniel. If your power supply is set to deliver a certain voltage (12 volts for example) then 12 volts will be delivered to the load device. Two positive and two negative wires running between the power supply and your device will not double the voltage. However it will double the amount of amperage the circuit is able to handle. That's a good thing but may be overkill. Remember, your device is the thing that will pull the amps it needs to run from the power supply and through the wires. If the device pulls more amps then the power supply can deliver then it will shut down (depending on it's internal protection) or burn up. If the device pulls more amps then the wires can handle then they may melt down or really heat up. The voltage won't increase once the voltage is set. Well,.... that's not entirely true. If your pulling more amps then the PS is designed to handle or the wires are too small or run for a long way then the voltage may sag but what I described above may eventually still happen.
Sounds like you need a few lessons on how to use and read a multimeter. That's nothing to be ashamed of. That kind if knowledge is not intuitive. It takes study and hands on experience to understand what your readings are showing you. It's not always as easy as looking at the reading and either seeing or not seeing the voltage you expect. Sounds like you're well on your way but need some more exposure. My advice is to read all you can on this kind of testing. Also there are lots of Youtube vids on how to take different readings with multimeters.
Good luck, Dave Schulpius

BTW, that looks like a molex connector and depending on the size you buy they max out at about 10 amp capacity. If you need to know what amperage a connector will carry it's always best to look at the specs of that connector at the distributor or vendor's website.
