    Post Removing AC filter components

    Ok so i mooched a digital camera and got some shots of the AT PSU im going to modify.



    The AC stuff is in the red box and i understand those blue disc caps have to go as well as the transformer/coil/whatever.
    The white boxes on either side of the coil are marked as indicated below.



    As far as i can tell they are caps as well, hooked up on the other side the same way as the blue caps, and therefor should go
    But they are strange looking Caps (compared to my limited electrical expt.

    So.. Stay or go?

    good work dude! okay this helps.... get rid of the white caps and the blue ones like u said. the black/yellow coil/choke will be in series with the input supply - unlike the capacitors which are wired in across the input.

    it needs to be removed, but when u do there will be a break in your supply, so you will need to replace the coil with some wire to complete the circuit. but i would trace the underside of the PCB to make sure this is the case.... but im 99.9999% sure it is....

    so yeah to sum up, the caps are in parallel - just remove em. the coil is in series - remove it and replace with wire links...


    hope that helps!

    thanks champ, nar thats okay tho... im getting a new camera VERY soon. I guess i thought the images were okay, since I understand them! oh well....

    i guess speaker wire will work.... i just used some old resistor/capictor wire legs.... worked fine for me. its doesnt need to be a huge gauge....

    be sure to write up how it goes...

Next weekend is ground everything possible, and that still doesn't work the inverter is going back to Canadian Tire, good thing it was on sale. (That is unless i find some Christmas lights for the rear window )
