I was thinking that testing voltage to amp pins would be sufficient, but as you have described that I need to test correctly, what kind of tester would do this and is this done through the pins?

T32h/1 - Power
T32h/2 - Ground

Test them both. Put a load of 10A on the wire, if it passes that test, wire is OK and amp is bad.

Thanks Golfi. How do I put a load of 10a on the wire. Is that just a case of staring the engine?

You take a powerful lamp, 120w for instance. Because of the ohm law P=u*1 and I=P/U
So it makes I=120W/12v, I=10A.

Hope you understand. :) PS bulb has to be rated for 12v. :)

Sorry Golfi. My brains fried, I have no idea what all that meant. I have read it five times and the more I read it the confused I get.

Is there an easy way to tell me what to do without any complicated stuff.

Sorry I need an idiot guide.....

Put 120W/12v or similar power bulb at the pins of amp. If the bulb lights up fine and bright your wiring is good.

But i would suggest at this point, to seek out a help of experienced electrician.

This is what I have done so far. I have a pencil voltage tester that tells me the voltage when I touch a live wire. I unplugged the amp and I found that when I first did it I got a 12v reading off the the first pin and nothing from the second and then the power went down totally. What I found was that when I unplugged the amp, the mmi went blank and the power cut off to all the units with the amp like DVD, radio and tv. I don't get any readings at this point, I'm guessing when it's plugged out, it cuts the power to the cable
