Voltmeter

[carl62cycles]

Wanting to install en extra Digital display voltmeter.( have the oem analog).Have found two different styles...one 2 wires 4.5/30 volts red & black and a 3 wires red/black/yellow or white 0/99 volts.I guess the red/black wires can be installed directly to the battery (can add an on/off switch to avoid battery drain.Question is where does the 3rd yellow or white wire connects to on the triple wire voltmeter? :headscratch:

Good question.

I don't think it would be a backlight since it's a digital display....Hmm.

where would one find a vot meter like this?

On component mobile audio systems, the yellow wire is sometimes a remote turn-on. It is on the Clarion system on some of our bikes.

If the yellow is a remote turn on you'll know once the red and black are connected if the display doesn't come on, in which case give the yellow positive will turn it on.

Sounds logical,will do some research :read:

I was searching the bay :laptop:

That third wire is most likely connected to the dash lights, so the display is dimmed for night use.

I mounted one in the cubby hole of my old Dodge:

Two wires, one to the ignition side of the switch and one to ground.

Here's one on ebay: https://www.ebay.com/itm/DC100V50A-Dual- ... es&vxp=mtr
A volmeter and ammeter combined.

From a Similar Voltmeter on eBay

Wiring:

Red: Positive +
Black: Negative -
Yellow: Voltage measured
What I would do is connect the red and black to a 12v source and if you get no voltage reading touch the yellow to the positive should see the voltage at this point https://www.ebay.ca/itm/DC-0-33V-Blue-0- ... 4d04cc891d

I used a simpler meter there is a voltage range for all three colours but basically red is bad yellow is low green is good green flashing is high green flashing quickly is over voltage

I wonder how much (if any) of these Chinese electronics are tested for safety.
I've had cheap power strips for home melt down and start a fire.

I have decided on the two wires one.I think that less wires the better :read:

I''ll go the same route with red :thanks: :thanks:

I wonder how many of you use laptops or computers made in China also. All three of my systems ( 2 laps and 1 desk top ) are Chinese and so far no problems.

I guess we are at a point that most of the electrical appliances around us are made in the far east.Here is a photo they add under one of their selling ads....... :fishin:

Now if my Voltmeter is going to be delivered to the Port in this manner :smilie_happy: :smilie_happy: I really have no clue :smilie_happy: :smilie_happy:

I've had good and bad experiences with products made in China. Sometimes I take the risk and some do not. The goal for them is mass production and produce as cheaply as possible. To produce cheap products need to acquire low-quality materials. Labor can be good, but if the components are not of good quality, the final product will be a question mark. Possibly last 10 years, or maybe two weeks. Who knows??? :headscratch:

When I was a kid we used to say all this about Japanese products, now we have hundreds of blogs like this one dedicated to them.

While it may be true many of the new breakthrough inventions come from North America (and Europe in days past), if not for the east we would still be "getting the bugs out" of our computers with brooms.
