So, I ended up with a flat battery. Recharged, started fine, but I have a low volume continuous alarm coming from the dash. Any ideas how to reset that?

 

Welcome to the forum

We are based in North America and our Rangers here were 1983 to 2011 and smaller than the T6 Rangers sold in the rest of the world, so not the same "Rangers" just the same name
It reads like you may have a T6 Ranger
Try Australian Ranger forums, they used the T6 Rangers and English language
Also include the Year and Engine model with questions in any forum posts
