Yes, it is a 6-gang charger. I am having trouble understanding the "TTL" line from the main board to the PSU; it is in a very tight spot and thus difficult to get a probe to it.

At my local ATC squadron, we have a number of MT6000E hand-held radios. The charger is an NTN1177A, but it's getting wonky (it cuts out after a few moments of charging). What I'd really like to obtain is a copy of the Service Manual for this charger.
The PSU inside the cabinet is an ASTEK AA16330 ...
