Hi, I have a 2007 3.0 D4D and I got a weird issue tonight when trying to head out. It has a dual battery setup through a redarc BCDC1240 though it was inactive as I have it on a switch to only charge the other battery when needed.
I turned on the ignition and seen my primary battery was sitting just above 11v. When i turned the key to start the engine i head a click / brief noise from the engine bay. Sounded like a relay or maybe fuse blowing and then I lost all dash lights and all electrical power. The engine didn't even try to turn.
I removed the key and waited but now have no electrical power to anything. Using my multimeter the battery is sitting at 11.5v.
The only other relevant info I can think of it that earlier today I used the Hilux to jump start my Celica which had been sitting for a while. Not sure if that could have done anything.
Would appreciate any pointers towards what to check. I'm hoping it's just a fuse but not sure which one to check.
Thanks, M.
