kicker 1500.1

mike49504 · 10th February 2010, 03:29 AM

Im rebuilding the power supply in this amp. All fets were toasted most of the gate resistors were bad and the driver also are bad.

Wondering if there is a good sub for the drivers B647 and D667 ?

ok nevernind i found the originals

mike49504 · 12th February 2010, 06:19 PM

I replaced all fets(3205's) in this amp replaced the gate resistors (100 ohm)
replaced the drivers (B647 and D667) and a couple 10k resistors next to the gate resistors.

When powering it up through a 1ohm 10 watt current limiting resistor it still draws 15 amps of current and the fets get red hot with 1 to 2 sec's

I pulled the rca jack board and the other driver board in it still draws current and fets get red hot.

Wondering where i go from here?

Did you try pulling the rectifiers?

Are any outputs shorted?

mike49504 · 12th February 2010, 07:17 PM

Do you know what they are using for rectifiers in this?? Outputs are out of the amp and it still draws current.

Not sure what the rectifiers are in this amp The F30D40D?

Yes. Those are the rectifiers.

Ok pulled the rectifiers in the amp now it powers up and idles perfect. So something in the output section. Wondering where i start checking

Discharge the rail caps and measure the resistance across them. Do any read anything near 0 ohms?

Are any of the rectifiers shorted or leaking?

mike49504 · 12th February 2010, 08:13 PM

How do i discharge the rail caps?

Short the terminals of each capacitor (preferably through a dummy load or other resistor).
