Can anyone help me either with a wiring diagram or tell me which of these 4 pins I should apply power to?

Thanks,
Pat

Hi Pat,

Are the wires coming out of the back of this connector color coded? There are standards designating the color the insulation is according to what each conductor is carrying .

Hi Steve,
Thanks for helping me out. Here is a photo of the colours.
One pin has 2 black wires on it the other just one. And then there is a red pin, a brown pin and the green ground connector.

Black should be the "hot", and should go directly to the fuse (please check, "should" and "is" aren't the same as much as we want them to be!)

Correct! Green is chassis (also check: your life may literally depend on it!)

The other two I am not sure of. I'd like them to be one wire and white for return, but they are not. It could be some funky settup to allow worldwide use just by changing the line cord, but that's a guess.

Can you trace them out?

Janice? Youi have one of these. Any light to shed on this?

The red wire appears to somehow be connected to the grey wire which goes to the 115v terminal:

Brown guy goes to the big white gzizz

STEVE, ..the red wire also appears to go to the AUTOSTART switch.
AND the single black wire goes to the on off switch.
AND the black with white stripe wire goes to the speed adjuster (it is on a pin with another black wire.) If that helps at all. Thanks

Oh, My!

It seems there is more happening here than just power!

(I'm guessing you are missing the original line cord?)

Yes that is exactly right. I've asked that if anyone has one, could they measure voltage on the pins, but so far no replies. So am just grasping at straws at the moment.

Thanks again for looking at this Steve. I'm off to work so won't see anymore posts til around midnight.

These machines come up here quite often, so someone will be able to fill in the blanks. Personally I don't have one so the best I can go on is general knowledge.

Good Luck!

I'm out of town this weekend. I'll check my FP-A when I get home tomorrow...I'll chime in if I can add anything to this thread. Electrical knowledge is not one of my strong points.

I just bought another FP-A for parts...but it didn't come with a power cord either [Frown]

Hi Janice . Thanks for your help too. I really just don't know how that power cord is constructed.
If it has a grounded 3 prong plug on the one end going to basically a 5 pin connector ...(that is if you count the ground) ...then 3 of the pins must be hot? and one is neutral?
Or 2 hot and 2 neutral? Like 2 separate power cords in one with a common ground?
Do you think that's possible Steve? .......Anyway, It's Very strange.

Hi Pat,
I've only used my multimeter to test fuses [Frown]

If you can guide me to how to set my meter...I can try and measure the voltage for you. I imagine I will have to plug it in...will this be dangerous [Confused]

Hey Janice Excellent!
Please don't do dangerous... If you could just measure continuity from the plug in end to that connector with your ohmmeter that should be good enough I think.
I'm assuming the other end is a 3 prong as in the picture so if you could tell me which of the blades on the plug in connect to which of the pins on the 4 pin connector end,
I should be able to cobble something together.
Thanks very much for doing this.
Pat

Believe it or not...there are only 2 prongs on the end of this plug. I did the continuity test. One prong had continuity with each of the two Black sockets on the other end of the cord and the other prong with the Red socket. I hope this makes sense...not sure if I'm using the right terminology [Smile]

There was no continuity with the Brown socket.

Please post if you assemble a DIY plug and if you need any further info let me know.
