How many LED gauges to one wire?

Redog · 04-06-2010, 08:51 PM

Hey all.

I'm putting new gauges in my "A" pillar and in the cluster thingy I bought from Never Done and I was wondering how many gauges can I put on one wire, LED wise.

I'm going to Auto Meter gauges and I'm looking to make the wiring simpiler than I did when I put in the Faze gauges. The Faze gauge lighting had inline glass fuses in each gauge. Each one is .5 amp fuse.

Could I wire all 5 to one wire and use a 5 amp fuse? I'm probably going to wire the 3 "A" piller gauges on one and the 2 cluster gauges to another and use 5 amps on each.

Only the lighting part

.5*5 = 2.5A allow a little variance for power fluctuations (turning on and suck) a 3A fuse would work fine.

yes, you can power them all off the same line. Using 5 amp would be overkill. You would surge and damage them with much less then that.

Cool thanks Chris.

I knew this was up your alley

i have all my leds run off one wire.

you'll be fine. Just be sure you use solid connections. Don't twist the wire together and cover in tape.

...in other words... don't be ion.

It's the fuses part that confuses me. I have so far tapped into gauge harness for my overlays and the leds on my floor... when do I need to worry? Lol I think Im already pulling an ion?

the things you tapped, already have fuses protecting them.

your need fuses if your running a brand new line OR want more protection for each individual unit.

But you don't want your fuse to be way over your draw. For example: If you have a unit that draws 2A you'd want a fuse at 2.5 or 3 Amp since a 5A fuse is more then twice the draw of the device. There is a good chance that kinda of boost would fry the circuits inside the device.

Redog,
Since you have helped me with gauges, let me tell you how I did mine. I have glowshift tinted 7 color LED gauges.
What I did is run a 14 gauge RED wire of the RED wire of the radio; Do the same EXACT thing with a YELLOW wire. Then run all of your grounds to the same contact (ONLY IF A VERY SOLID AND GOOD SPOT)! then all you have to do is run the sensor wires and plug into each individaul gauges and boom done.
Hope this helps.

NO TAPING!!!! TAPING IS FOR WOOSIES, use simple butt connectors if your NOT very good at soldering.
