Bench test

[KEEBIE]

Hi
I`am new to all of this stuff,is it possible to make a bench tester to test power to the amp.?
i now that it needs 12v, and a earth,what is the volt of the blue remote wire ?

cheers Gary

I couldnt find a decent power supply so I built my own.
Variable from 0-20 volts also variable current from 1ma to 10amps.

Has meters for both voltage and current, allows me to monitor an amps power draw, can be very helpfull in diagnosing faults.
Also helps save amps from further damage.

The remote wire (blue) is only a low current sense wire. 12v maybe 2ma.

The remote wire (blue) is only a low current sense wire. 12v maybe 2ma.

so would it be okay to use a wire from the ignition switch ?

Ummm, look, what are you trying to do ?

First you say 'bench test' then you talk about ign keys.

Why would you have an ign key/switch on a bench ?

Am I missing something here ?

With all due respect if your struggling to understand the basics of amplifier power wiring then I would like to suggest that you STOP whatever your doing and read a heap of books about basic D.C. theory.

Not being nasty, just trying to help you as much as I can.

Use something like this:

Astron and Tenma make great power supplies. There are (-) and (+) binding posts on the back of the unit. And yes, you can simply hook the remote of the amp up to the (+) of the power supply terminal.
