Re: 12v/24v tester

Go to any electronics parts supplier, and spend a few dollars on a low cost
DVM. Then buy the parts required to make up a test plug that you can plug in
to the cigarette lighter for taking voltage measurements.

When using a DVM, just make sure that the meter is set to the proper range
before connecting, to avoid damage to it.

Hi all,

I was hoping someone here can help me out please. The problem is that being
a truck driver (in the UK) there is no universal way of the cigarette
lighters to be wired for one of the above voltages. For example, Volvo might
have one cig adaptor fitted and it could be of the type thats found in cars
but it migth be of either voltage. A different truck manufacturer, say
Mercedes, might have the same cig socket fitted but the voltage stepped down
to 12v. So theres no definate method of supplying 12v to the cab to run
ancillory equipment from - and I carry a fair bit with me whenever I get
into a truck such as portable TV, cooler, satnav - the list goes on. Im sick
fed up of blowing the balls off my gear with 24v really!
So I need a little help here as such - Id like someone to draw me a simple
wiring diagram with components labelled whereby I could use a cig plug and
wired to it would be a little circuit board with 2 LEDs - a green one for a
12v supply and a red one for a 24v supply that would warn me of the voltages
when I plugged it in.
Im no Einstein by any means but im not completely daft either. I can use a
soldering iron and solder all the components into the striped circuit board
thats generally available from Maplins etc.
Please someone help because this has gone on for a long time now and its
starting to get expensive too.

Thanks in Advance.
