pbutler - 3/11/2026 11:57 I run a Kinze 16-31 with 31 sure drive motors. ISO kit on the back of tractor. Last year about 1/2 way through the season I started getting errors about "low can bus voltage"-some rows or sections of rows would go offline and come back online. It was intermittent-seemed to be heat related. Was almost sure it was voltage drop due to harness rub or something but never could identify it. Went back to corn in 16 row mode and was still having issue even with only 16 rows. In diagnostic screen on 1200 some rows red, some greeen, some flashing low. Had AgLeader tech out and he started checking voltages from the tractor-found the Canbus voltage from tractor was 0. Pulled the cover off bottom of ISO retro kit and there were two tower fuses I did not know existed there-replaced them and bam-everything green again and working fine. I am happy as can be but what I can't for the life of me figure out how it was working at all with the fuse blown. It must have been blown a long time. Where was the can-bus getting powered from to work at all? Only thing I can think is there is a can-bus repeater on there to boost the signal-was it somehow providing enough to limp along? How do they work together-seems odd with two different power sources constantly feeding. Just curious at this point.
