Looking for some advice. Left the country for a month. Come back and go to drive the land cruiser, doors wont unlock. Unlock with key and go to start, completely dead, no lights on the start button or dash. Assume battery died while gone plus I also dont drive the truck much right now so it sits alot of the time.
Pull battery and put it on charger. Next day battery shows fully charged and healthy according to the NOCO. Battery is exactly one year old, Its a True Start purchased from Toyota dealership August 1, 23. Throw it back in, fires up and drives no issues. Sits for a couple days, go to drive it third day completely dead again, wont unlock no lights. Take battery back out put it back on charger shows its dead again. Was going to let it charge but instead go to dealer and get a brand new replacement. Throw it in, everything works perfectly. Drive it for the next two days after, multiple starts, multiple trips of various lengths, no issues. Thinking i'm good to go.
Truck sits for two days. Go to run an errand a few hours ago, door wont unlock. Thing is dead again. Have no time so jump in another car and do what I had to do. Come back unlock the door, push brake, no lights completely dead no power. Will not beep or unlock, no lights on days including the 'doors are open' indicator. Absolutely nothing. Thinking I have a parasitic drain of some kind and brainstorming where to start trouble shooting. Pull the 6 day old battery out and look at all the fuses under the box under the hood. All fuses look good. Terminals look good, atleast the parts that are exposed and visible while standing in front of the truck.
Heres where it gets good...Expect brand new battery to be dead, put on Noco, turns green instantly indicating fully charged. I have no idea what to do now.
Guess need to take a better look at the terminals and follow them all the way through to chassis. Any other ideas how the truck would have a healthy charged battery but have absolutely no power inside?
Doesn't make sense how it drove fine for two days with several restarts/trips. Too busy with work to take the time to troubleshoot, will likely have to wait until this weekend to look into it. Any help is appreciated
