Board # 0764-f
Worked fine on the bench in stereo but, when installed mono, it acted like the power was "pulsing" as it would play shortly then off a fraction of a second and so on. The LED would dim and then brighten.
I found a burnt trace located in between the row of resistors R12-R14 and the crossover card.
Does anyone know what may be the cause?
Thanks

I soldered the trace and it seems to be better now. I'll have to do more testing later. It did introduce a random "click" on the subwoofer preouts of my deck though. Reinstalled the original amp and the clicking remains...
With no RCAs plugged in, the resistance between the input RCA shield and the main ground should be approximately 1k ohms. If it reads near 0 ohms, it has a shorted diode.
Uninstalled my head unit and discovered I may have used the power antenna lead as a remote by mistake. It may not have been the amp?
Disassembled it to find out the battery is dead in my meter with no spare. I may have isolated a defective diode before the meter went down but not sure. Back in my truck it goes until I get another chance to look at it.
It's a long shot but does anyone happen to have a schematic for an Alpine CDEW265BT?
