Hello, all!
I just got a used Mastech HY3010E-3 and it appears to work fine in PARALLEL and SERIES modes but in INDEPENDENT mode, slave side does not function at all.
I do have the two pushbuttons popped all the way up to activate INDEPENDENT mode to no avail.
The free-standing 5V section works fine (4.89v on the meter).
Also, FWIW, I can't adjust the AMPS at all on either side, regardless of the mode.
I repair arcade games and pinballs as a hobby, so I'm hoping with some guidance or a schematic, I may be able to repair this.
UNLESS - it's not broken and I'm missing something. I have RTFM and there doesn't seem to be any mention of an overload reset procedure for this model and I have tried all the suggested settings (dials fully clock-wise, etc.). Does the slave side need a load to operate properly perhaps - no mention in manual either way.
TIA!
