Hello All,
Sadly this is my first post here on the forums. I actually have a 2015 RC350-F, however, I'm posting in the IS section in hope to get more views/responses, hopefully from a Lexus Tech. Started with a trip to the vet for a sick animal. Hours later we left, tried to start my RC, only fast clicks, but I could still power accessories like the moonroof. So I'm positive it was the battery. I noticed that I've lately had a habit of hitting the damn touch-activated passenger maplight when closing the moonroof, and think I left it on overnight.
AAA said 2 hours for a jumpstart, and the vet was getting ready to close. Couldn't find cables from any of the animal hospital employees. Anyway, got a ride back to my house to grab the girlfriend's truck and jumper cables and headed back. It's been a long day for me after having been up all last night with a sick animal, and being at the vet all day.
So I went to jump my car from my girlfriend's Audi Q3, and not in my right mind, I figured the covered battery post was the positive as it is on most cars, but no - Audi covers the negative terminal for some reason. In the end my fault.
TLDR - I ended up connecting the wrong cable clamp to the wrong terminal on the Q3, connected to my RC, and the cables got fried. Disconnected them as quickly as I could but now my RC has no power whatsoever to even unlock the doors, but I did notice the vehicle proximity warning lights on the mirrors lit up before it completely died. Her Q3 is completely fine. I know my battery is toast, and I was going to replace it anyway, but someone please tell me that the main fuse/link should have caught this before doing any serious damage to the ECU, etc. I forgot to check the fuse box before we left, as my mind was about shot at the time.
Thanks in advance for any input.
