We still rebonded the BGA and chip and checked the power transistors. After powering the unit up, it still didn&#8217;t work. Diagnostics reported electrical issue with the hydraulic pump. Back to the bench!<\/p>\n\n\n\n<figure class=\"wp-block-image zoooom\"><a href=\"https:\/\/imgur.com\/1G1xYAl\"><img decoding=\"async\" src=\"https:\/\/i.imgur.com\/1G1xYAl.jpg\" alt=\"\"\/><\/a><\/figure>\n\n\n\n<p>Having separated the motor from the hydraulic unit, it was time to open it up and check the state of the commutator\/brushes.
