    I'm Peter.

    Default Pathos "In the Groove" MKII Phono Stage.

    Firstly, is there a member on the forum that owns one?

    Secondly, I had a senior moment when I went to install new Lead Acid batteries and forgot the connection lead positions.

    Does any know how these batteries are connected?

    Emailed Pathos but no answer and dealers are obviously not open due to lockdown.

    Not going to connect the batteries until I 100% know it's correct, for fear of damage.

    Any help much appreciated.

    Picture below

    Easy to work out. The two grey wires are the 'common' of the two batteries.

    Taking the terminals as shown in the photo, Top Left, Top Right, Bottom Left, Bottom Right.

    Grey wire to top left.
    Grey wire with red mark to bottom left.
    Black wire to bottom right.
    Red wire to top right.

    Thanks firebottle. Are these the voltages you would expect? (Not connected to mains)

    Red / Black = 12.96v
    Grey / grey red = 00.00v

    Voltage from each individual battery

    6.40v
    6,53v

    When connected to mains voltage..

    Voltage whilst charging = 13.20v (slowly climbing) 13.38v / 13.56v( reading taken from red: black connection. ( No voltage on Grey / Grey Red terminals.)
    Sorry, I've turned the batteries within the cradle but connected as per your instructions.

    Peter

    My impression is that what you have done Peter is right, it looks as though the two cells are in series, the grey wires being connected together.

    I do hope so

    I exchanged this kit (and quite a load of money) from a Mcintosh / Whest combination.

    Many would disagree but I personally consider this battery phono to be the best I've heard to date. Perhaps it just matches the Pathos InPower / Incontroll kit.

    I will photograph everything in the future before messing with it.... I feel a complete numpty.

    All appears to working as it should.

    Just waiting for a response from Fire bottle before it goes back on the rack

    Many thanks for your advice and help, it really is appreciated.

    One final question. When the unit is is charge mode, there appears be a low level hum / vibration from the transformer after the charger has been on for an hour or so.

    There is absolute silence when the unit is first switched on.

    This can be stopped by just pressing on top of the casing and appears to be a mechanical vibration. Never noticed it before.

    Is this something to worry about? Or is something about to fail.

    Obviously, I can get it into a dealer after lockdown is over.

    Put a weight on it and forget about it.
