LC randomly goes dead (no power to car) even with full main battery, also power window issue

EXACT same issue with the aluminum extenders. I jumped from battery to wires to get it started again this morning and take to a shop. I think it’s ruined my $500 battery by the drain. All connections are tight.

First thing shop said this morning was “Aluminum? Why?”

I’ve been lurking this forum since buying my LC200 a few months ago. It was already built out by the previous owner with a lot of slee gear and it looks like great work so far. But I’ve been chasing this exact same issue. The truck would fail to register any electrical activity at all after turning it off until I fiddled with the slee battery terminal bus bars. I ended up cleaning all connections and adding a jumper from my battery terminal to the original harness. All issues resolved immediately. Thanks to this thread for saving me from throwing away money at the dealership.

My shop made a similar slee extender out of metal and truck worked perfectly. Aluminum and electrical

Interesting; do you think your shop would be open to making another set?

OTOH... I've had a Slee tray and those extenders installed since 2017. Not one problem, ever.

Not sure if it helped, but I always spray battery connections with a protector product.
