Ok, I did all the testing you outlined above and found that one of the keypads still had the J1 jumper installed. When I removed it and retested the Bus measured at 72.1Ω, which is just outside the range you mentioned but much less than 120Ω and better than the 51Ω I had. I have cleared the log and will monitor it to see if the random startups disappear.
Thank you for you assistance with this.
