Default Radiomobile 8track 102s

I have a Radiomobile 102s that’s been converted to positive earth.
Does any one know how to change it back to negative earth.

You'd have to open it up and look at the circuit and ground points to assess the simplicity of reworking. Can you read a schematic diagram?

IIRC, these were Negative earth ex-factory, but I no longer have any service info. for this model, and don't remember what was involved in changing the supply polarity.
