Mate congratulations. Legend.

No need to thank me.
You have the right attitude, willingness to do work yourself, persevere if things dont immediately get fixed, and show resilience. You appreciate the hlep and advice you get.. AND, what I personally most appreciate: you come back to the thread and tell us what worked and did not work, what else you did, and that way gave us something to help you further with. With that combination, like I said, we would get it.

As for the battery; yes it can cause all kinds of weird issues.
Good thing half your engine bay is now renewed and good for another 20 years haha.

If you ever get to see a post from BlueRidgeMark, look in his signature, item 4 and read post #5 in that thread. Relates to you as well imo.


Well done mate, save travels.
