Hello everyone. First time poster, first time L322 owner, long time Landy owner (D90s, D1, D2, etc..).

I am in dire need of some help as this morning, I have a total loss of electrical power on my 2011 L322. Battery voltage is 12.9 but nothing turns on. Except for the tail lamps... they are on for some reason.

The back ground, yesterday, I was having some trouble with my radio - the main power button was not working. The rest of the head unit worked but the functionality of the main button seemed to be broken. So, this morning, I decided to do a hard re-set and pull the battery power. (I read on the internet that this might re-initialize the radio..). But, when I went to put the battery terminal back in, nothing was working?

Any ideas where to start?
(I will check the main fuse this evening, Didnt have time yet... sitting here at work. I am thinking that maybe it popped when I applied battery voltage back (inrush current....???).)

You’re probably on the right track. Did your clock and date go loopy and set to 2009 or something?

Check that the cables are on the poles tightly, especially the negative.
Put it on charge to boost the battery.
