Rockford Fosgate T40001BD Repair

Perry,

Sorry for the delay in getting back with you. Turns out after replacing the FETs and replacing all the components of the 4 drive circuits it powered up and played perfectly. Thanks for all your help...

Now, for the next one.. I have another T40001BD that someone else repaired and they're work is somewhat questionable. I first opened the unit up and diode check the outputs and the powersupply chips. Everything seems fine. So i powered up the amp and everything is fine. No protect light until about 10 seconds. Amp meter on powersupply is around 1-3 amps and then jumps to 10amps. Nervously, i power down and check for hotspots. Nothing obvious, I power up again and check output voltages. I read 110v on half the outputs and then the unit goes into protect. I remove power and remove the +hv, gnd, -hv from the output board and power up. Unit stays out of protect mode now but i seem to have higher voltages from the previous amp. I am reading 184v from +hv and -hv. Does this seem normal or high? I was expecting around 120 or 110V.
