JL Audio 600/1 V3

Amp will not power up .

It came in with blown power supply fets gate resistors and drivers

Replaced those parts . Now the amp will not power up .

I get 0:00 volts on all pins of the 3525


Any ideas ?

It's essentially a 500/1. Do any LEDs on the outside indicator light up when remote is applied?

 

[caraudioguy2100]

No

Is it on signal sense on?

If so, switch it off.

If that's not the problem, post the voltage on all of the pins of the 10 pin connector as labeled below.

Guess I’m tired .

I switched signal sense off .

There are no outputs in the amp right now .

When I try powering the amp up the green light pulses and you can hear the amp trying to start it cycles over and over .

Would no outputs in the amp cause this ?

 

[caraudioguy2100]

Installed the outputs .

Amp still does same thing .

When trying to power it up the green led pulses and the amp cycles and attempts to power up

 

[Perry Babin]

Remove the rectifier. Does the amp still cycle?

Found the problem

One of the drivers for the power supply fets was leaking
