you are possibly still using. I purchased the same converter and someone has been doing some rewiring. Now when you plug in the converter.. it reverses the 12v polarity. I have no idea why you would want that but need to restore it to factory. Any chance you could open that converter and take a picture for me?
Looking at the manual Dave provided, the only way I can see the voltage would be reversed when plugged in is if the diodes 1 and 2 are reversed, so that when Relay1 is closed it would reverse the voltage on the external load connections. Relay1 is closed when you apply power to the converter. But if you reversed the diodes the battery charger section would not work either, so I'm confused.
As Dave said these old converters are not very good, if you can afford it I would do something like Dave has done with the PDD converter with the Charge wizard or an Iota converter with IQ4.
Looking at the OP's pictures, you should be able to wire the new converter into your existing fuse panel by removing the Blue and Red wires from the left side of the fuses, which would disconnect the Phillips converter and wire the (-) lead to the large lug the white terminal goes to (wire in parallel with the existing white wire) (+) lead to both places where you removed the Blue and Red wires.
Also, make sure to disconnect the power to the Phillips converter, which I believe is connected at the two Red wire nuts in the lower left of the picture. You will need to determine which wires come from the power source with a tester or DMM (carefully, 120V can kill) and remove them at the breaker box, insulate them (I just screw the wire nuts back on) or use them to power your new converter.
You can also gut the innards of the Phillips converter (the transformer, components, wiring and any circuit boards) if you want to save some weight.
You'll have the benefits of a modern converter which will quickly charge your batteries and not boil them if the pot on the Phillips is set wrong (and with my old Magnetek, even if it was set right it would drift and overcharge the batteries).
