| I do not think RCM 1 and RCM 2 modules can/should be combined together on the same planter. I would be really surprised if that was actually your case. Are all your RCM modules the same shape with the same style connectors? RCM 1s vs RCM 2s should look very different from each other
With RCM 1s a common cause of low CAN voltage is voltage drop across a bad connection or cable somewhere. Probing around with a multi meter in a few place might help narrow it down | |
