Hey,

Just got my SL63 out of storage (Was a long 6 months )

Car fired right up, but I discovered that my heated seats don't work (indicator just flashes) and if I goose it in a corner, the radio seems to reboot, and the instrument cluster complains about abs and a couple things for a split second.

I checked the battery connections for both the primary and secondary battery, they seem tight, no crusting on them, and no obvious signs of external failure.

Don't have a multimeter with me, and I plugged my innova code reader into it and it didn't say there were any stored codes.

I'm thinking one of the batteries failed, and should probably just take it to the stealership.

Pretty sure it is a failed battery. The dash lights are flickering like mad, and it refuses to do anything with the key fob after about 4 seconds of it being off, but it fires up properly every time.

Gonna replace the rear one and see what happens next.

take it to a auto parts store and have them diagnosis both batteries, they will know if they are good

It is your accessory battery. The flashing heated seats indicator is dead give away. The flashing abs and/or ESP indicators on the other hand usually point to weak main battery.

Charge both with a conditioning charger and let us know.

Yeah, went to autozone/partsource while the dealership is closed, their handheld unit says rear battery has 3.96v.

Will stop by the stealership tomorrow, and putz around in a E550 or something while they change my battery.
