Installed a PS2 upgrade kit in an MTH MT-3020LP Hudson (20-3020-1 modern terms) and loaded software using AC power. Loaded a 1meg, 3v file for a PS2 Hudson. The engine would not let me upload using DC power. Used the Technician Loader, upon checking operation, the speed increases in both directions wildly in DCS mode. In conventional mode speed is ok. No abnormal high current, no pinched wires. Performed both feature and factory reset. I THINK a component on the board is defective. Have performed many upgrades, both ps2 and 3 and this is the first time for this to occur. Could this also possibly be a software problem?
This problem is mainly for John Will or George. If a board component is defective, can it be replaced? I do not have a PS2 Test Assembly, only have PS3 test assembly.
