Disk System Battery Error 02 caused by Ram Adapter

[toploaderleo]

So I have a few Disk Systems I've been fixing & came across a very strange issue. I have a Ram adapter that always gives me Error 02. I know it isn't the Disk System, the AC adapter, or the Famicom console because I have a RAM adapter that I know is good & swapped this bad one out for the good one & didn't get the error. I was wondering if anyone has any idea how to fix this RAM adapter, I've already opened it up to check if anything was physically broken or disconnected.

Figured it out! It was the cable. The only simple thing I hadn't tried was checking if there was connectivity on both sides of the cable. After checking all 11 wires I found one had a short, not to far from the RAM adapter side of the cable luckily so I had to cut it, strip all 11 cables, reconnect them all, tuck them all inside the RAM adapter housing & when I tested it that time it booted up immediately.
