How do you know which voice coil wire is + or -. I have replacement 750 coils just like these and they are not marked to show either RED or BLACK....+ or -? I hope you can help - no other videos to see for advice. Many thanks!!!
you can 1st trace the wire back to the crossover , the + is connected to a capacitor. Mission use grey wire for - ,grey with black strip for +. if you find both black wire, the black wire with word on it is alway +
@@petermi1468 Sorry, you miss understand. I have bought the voice coil & silk domes to re-fit myself, but the extremely thin wires either side of the coils are not covered, they are bare, so I am unable to determine which way to solder them for 'plus & minus'. Can you help? Sorry I was not so clear last time.
@@petermi1468 Thank you so much for your reply my friend. I can now attempt to carry out the repair myself knowing that the polarity will be right. Thanks again for replying so quickly, that was awesome, Brother.
