If no one else can help, post a photo of the inside of the amp.

Does it spark intensely every time you connect power to it or only the first time you connect the power/ground?

j7523 · 17th February 2010, 09:18 PM

ya as soon as you put power to it it arcs or almost solders wire to input

j7523 · 17th February 2010, 09:21 PM

everytime it does, i dont leave the power hooked up because it pulls one hell of a load or current fairly new amp

If it does this without the remote terminal having 12v on it, it sounds like the power supply has failed.

Can you send me (or post) a photo of the inside of the amp?

Measure the resistance (no power applied to the amp) from leg 1 to leg 2 for the 6 large transistors (clamped to the heatsink) on the end of the amp nearest the power terminals. Do any read near 0 ohms?

one side was readin 1.4 to 1.7 the other side was readin 1.027 to 1.028 there was 3 legs on each one so I went with the outside legs on each one, I dont know if that was right or not I am new to this stuff

I need to know the resistance from leg 1 to leg 2. Your meter was set to diode check. Set it to ohms.

Look at the pin numbering in the attached image.
