Thanks for response - but I was switching the main, not the aux. Nice to know that will have some fun when the time comes though
So - pull straight up on plastic fuse box like you are going to lift the front end of the van into the air. It will release. Outside temps low 40s no breakage but no warranty on this method. Brute force is usually a looser for me but enough was enough
Have a really long extension on your ratchet. Might actually be able to get there without removing fuse box. just burrow in dead center front of battery through the rats nest.
Make sure before you replace battery the bracket fastener has started to thread or you will get to puzzle piece the battery in twice. Geeze.
