Yep, the GP amp that's mounted on the left front inner fender near the ABS equipment. New one lasted about 2 weeks. The replacement has been going strong for 2+ years. both came from MB.
I checked my GP first - using the battery charger method - attaching battery charger to each GP and counting the time until the tip was cherry red. 12-15 sec was my target. They all checked out leaving the Amp as the only possiblility. BTW, I also confirmed the wiring between amp and GPs was good using the WSM method.
