Stern MPU 200, capacitor question

(1/1)

AE35:
Hi guys

I just got this Stern MPU 200 board, and it seems there's a normal capacitor installed where
the battery used to go. I usually install memory-capacitors and I haven't seen this before.

Am I missing something? Why would there be a 4700uF 16V cap?

Thanks!

Ken Layton:
Whoever had that board before you probably didn't know what they were doing. Yank that 4700 uf capacitor out of there and put in the proper memory capacitor.

pbj:
WTF.   :applaud:

Does it actually work, though?

Ken Layton:
With only 4700 uf I would think it could hold memory for maybe 5 minutes.
