To fix this issue- Install a new fusible link or fuse on the Dodge, 4 gauge alternator cable. OR- Run a a new, separate 4 gauge cable. With a circuit breaker or fuse matched to the 4 gauge cable amperage rating. Run it from the TIPM positive battery stud. To the alternator battery stud. Disconnect and seal off the old cable down at the starter.

Follow 5rebel9's directions. Read my post and whole thread below, regarding the battery and battery sensor. Everything you need to know is covered in it. https://www.dodgejourneyforum.com/topic/18210-electrical-system-fyi-battery/

For clarification purposes here is my picture of the starter and cables in question. The top red cable is the battery voltage feed cable from the TIPM (under hood fuse box). The lower dirty orange one is the fusible link that connects to the alternator stud. Your fusible link is blown. I believe you have the 3.6 V6 engine. Please verify this fact.

The red clip has to pulled down to release the wire harness. Can you tell me the code title for P0070? So I can look it up.

Your going to remove the complete sensor from the front clip first. Then try to separate the connector. It is held in by a push in trim thing. Using trim removal tool with the slot in it will help While pulling it away from the front clip. Pull on the the left side then right side. Going back and forth. Go easy. The connector is going to be a royal pain in the -beep-

So what you have is the top cable. That is the battery voltage feed from the TIPM- (under hood fuse box). To the starter. The lower cable carries the battery voltage to the alternator from the starter stud. The smaller section is a fusible link. It protects the cable like a fuse does. Use a multimeter and check for battery voltage at the alternator stud. To find out if this cable is a problem. Here is a picture of my 3.6 starter cable on top and alternator cable fusible link below it.

Connector, yes. Easy access - BMC to the right of the glove box.

Thanks for posting this. I missed the part of do not use on aluminum. I'll leave this one for people willing to gamble on it. I aim to give good information, that people can use. Without causing any more issues.
