Re: Opinion on Connectors

That's was great, thanks for the laughs, I especially liked the woman in the background yelling out "idiot" too funny.

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,

Hi Dave
I periodically do meter readings on my connections when wiring. It was only after installing the slip ring that things began to get weird. For example last week my Gennisis power supply began to reset when I plugged one particular Molex. Yesterday it began to work fine. However later that day I blew a capacitor and possibly voltage regulator in my Wiznionski belly light circuit board when I powered up. Tom suspects either the voltage was too high or the polarity was reversed, I then checked the polarity with my meter and yep, it was reversed coming from that particular Molex. Today I'm removing all my wire coverings to double check proper polarity. Like an idiot I had taken out my fuse to that board and jumped that connection when I was trying to find the problem.
I'm now thinking the problems could lie with my slip ring. I tracked down the full specs and found it's heavy duty (up to 600 volts and 180 amps total - I should have double checked it) and I may not have gotten the wiring correct. I assumed all were interchangeable (each could function as positive or negative). I think I'll remove the ring and simplify the wiring.
Tom thinks the board is repairable.

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

Hi Bob
Thanks for the feedback.
I ran multiple wires from my primary power source to my torso and head components because I wanted to distribute the load especially since I'm using just a single power source (luckily he's not mobile). I think I'll try the single cable approach and then a power distribution block. I also discovered I was likely wiring the slip ring incorrectly. I need to do some outside testing before integrating it into my systems.

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.

Hey Daniel, sounds like you're making good progress and doing the right things. Sounds like you've found out the importance of fuses. I remember you and me discussing this a couple years ago. Too bad you bypassed it. Tom is a great guy to work with. Three times I blew up light boards I bought from him along with a few led's and each time he sent me repair parts no charge. The only thing he got out of it was a good laugh. He said I alone had the record of blowing up that many of his boards. LOL! That's one of the ways I realized how important fuses were. Happy building and have fun.
