I've had this amp in my personal truck about 2 years.. this morning I I got in and fired it up and the the speakers just made a constant thumping .. looked at amp and power/protect is flashing blue/yellow.. pulled the amp out its nice and dry as it's in a 14 escalade.. bench tested with the same issue.. I'd like to pull it apart myself is there anything I should look for particular
For all of the large transistors clamped to the heatsink, measure the resistance between the 3 terminals. You should not read anything near 0 ohms between the legs of any individual transistor, no matter the terminal/probe orientation. If you read anything near 0 ohms, post the circuit board designation for those transistor(s).
