Kenwood amp prob!

I just wanted to see if anyone could help me...I recently got a kenwood amp, an older model, for pretty cheap-But when I hooked it up I kept blowing fuses.  So I got a test light and volt meter and checked it all out...come to find out when I have the Power and remote wires connected, there is a 3 volt charge coming out of the ground slot....Any ideas on what it could be and how to fix it, I'm semi-knowledgable a/b electronic work so any ideas would be helpful!!!

does it blow the fuse as soon as you put it in, or only when you remote on the amp?

If it shags the fuse immediately, look for blown power FETs in the Power supply, if only when you remote it on, start at the other end and look for blown output drivers......

my god man.... who let  you near electronics???     never connect power to an amp if the ground wire isnt hooked up.....

if it blows a fuse as soon as you hook up your main 12 source then you've got either a protection rectifier blown or blown FETs in the power supply... remove them and power it back up... if there is no short then replace them all even if only one is blown...also check your gate stoppers to make sure they are still within tolerence....

First off I know how to install electronics, I was just doing this for trouble shooting...Ill hook up the ground and remote first tomorrow and THEN hook up pwr and see what happens then...so im sure ill be back to figure this out...also when you are referring to power FETs , what are you referring too, thats a new term to me...

ok ... over the weekend I replaced the diode for the ground b/c when it was tested by myself and a guy at an electronics shop, it showed to be bad...when i replaced it , put it all back together, i hooked up the ground, remote and power...as soon as i turned the h/u on it blew both fuses again...is this the FETs doing this? if not whare some other suggestions for this problem? Thank you for all the help so far!!!
