Yesterday, I re-soldered the main lead that goes from the memory to the strongarm chip and it recognized the RAM just fine. I put it into the car and it worked like a charm first try.
Then I parked the car, put the empeg into the trunk and two hours later the problem was back!
Any idea which of the four chips (I piggy-backed two extra RAM chips) it could be? Any suggestion as to how to fix the problem? Has anybody else with the piggy-back method had any problems?
