Tipm to alternators has extra wire

steviewhite907 · Oct 27, 2024

Hi guys I’ve been a member for some time. So, I just did an engine swap on my 2011 jeep liberty with a 2008 liberty engine. I’m having click no start issues. There are two wires from the tipm that I just don’t know where they go . Help please!

They are likely grounds. At least the terminal with many wires. Probably low on the left head.

Other, I am not sure, but a meter or test light might help ID the issue.

ok I’ll hound them on them on the left head then update . Thanks DadOsix!

From memory - one is a control voltage wire and one is a voltage sense wire - from memory (when my alternator was suspect). Not grounds.

Thanks Kiwi, ok I’ll plug them up respectfully to the correct spot tomorrow, will update results after

Update: Hi guys, so I grounded these wires and now I do get a continuous crank, instead of a click. Also my dash cluster is still lit up like a Christmas tree.

Note: I changed the pcm and I hooked up the ground wire in back of engine bay
