Head-unit

[rcluke]

Can i test my head unit by connecting the live and neutral to a 12v battery ?

or is this a rumour ?

that's the way it works on any normal car so i don't see why not just don't get the wrong wires lol

[rcluke]

lol, i'll have a good check of the wires before i connect them

Just thought you might want to run a fuse between them too just to be safe, but i think most run on internal fuses or something anyway? otherwise halfords would struggle to wire them up

or i could use my power supply i suppose

i doubt it would be a problem because theres no transformers used in cars or anything, just wouldn't want to see you blow it up from a power surge or something. electricity is a funny thing, managed to blow the sky box up last weekend cutting a cable in the garage which was connected to a breaker that was switched off, still have no idea how

I run a head unit in my work room right off a computer PSU, and as long as you know which wire (12v+, 12v Constant and earth), then great.

these are the 2 pages of wires in the instruction manual

which wire goes where on my battery ?

[rcluke]

right, car battery was flat

i put a link between the earth to the neutral on my power supply, a link between the constant live on the head unit and the live on my power supply.

then i put a link between the ignition on the head unit and touched it onto the live on my power supply

SUCCESS !!!
