You jump/charge the 12V battery to get enough power to open the charge port door and get the electronics to turn on to accept charging.If both HV and 12v battery are out, how to open the door/charger port? Thx…
Yes. You only need one 12V source to jump.Can I use one external battery to jump on R1T’s both internal 12v batteries at the same time? Which means both of them are connected together if do so. Thx
It looks like that second jumper cable is seriously lacking. It's too thin, kinked up even cut at the extreme left side of the photo?- it's probably not doing anything at all.. you need to get better cables to carry some current..Can I use one external battery to jump on R1T’s both internal 12v batteries at the same time? Which means both of them are connected together if do so. Thx
Software; I believe.Any idea what caused the 12V batteries to die?
