I was wondering if anyone can tell me what the silver rectangle box that sits on top of the battery pack is for. I'm having one or two issues that may or may not be related. The first is that I'm losing power to the motor although the lights remain on. The indicator lights suggest a malfunctioning temp sensor because the battery is cold (4 long and 2 short flashes). But the other thing I've noticed is that the connector to the silver box is shorting when I wiggle it - even with both the winter switch and main breaker off. I'm assuming this might be a capacitor of some sort but if anyone has seen something similar or has some advice, I'd really appreciate it!
This is on my C-124 (3 years old now with just over 10k on it).
