I've already looked at all electrical connections apart from the safety module itself, starting with the ignition switch this past summer.
Knee-wise, I do not have a replacement knee, but I got a staph from a "minimally invasive" knee operation, and I'm now looking at a second operation as an attempt to clear out the staph next week, along with a hospital stay and a pic line for antibiotics to treat any type of bacteria found from cultures taken from this second attempt.
