Concept2 PM2 Console Repair
The batteries leaked in my Concept 2 Ergo PM2 controller.
Made a bit of a faux-pas in that I cleaned the case in ISO-propal alcohol and it discoloured and partially removed the writing.

I ended up using a fibreglass brush to rub the dried acid away.
A 66uF capacitor fell off the board. I think the battery acid may have eaten the solder from under the "+" end. I did not have any in a "C" size. Used a 66uF TPS in a D size case.

Hi Frank, I'm trying to repair the same board. The copper trace that approaches C12 is etched away on mine, it appears it goes under C12 but not sure. Do you have any idea what it's attached to? Thanks, Joe
ReplyDeleteHi Joseph,
ReplyDeleteI just saw this. Sorry. I have given up on my PM2. Where are you? If you want to pay for the postage, I am happy to give mine to you.
