Looking for a working early PL 400 Control board

[Northwinds]

The two green ones Joe? One has a black outer sheath on it. Do I leave the other black one alone?

 

[Northwinds]

What is the part number marked on the bridge rectifier?

NTE and looks like 963D

The two black ones, they come from the transformer secondary windings. Insulate them after desoldering...

The 2 black ones attached to the bridge where it is marked "AC"

 

[Northwinds]

I don't have a soldering gun handy, can I just snip them off close to the solder joints and tape them off?

That number is not ringing any bells Ron, you sure of that?

Yes, very close to the tabs so you don't loose much wire length.

Here you go Joe

Ok, snipped and wire nutted, did I do it right?

Yes, looks fine Ron. I believe the 963D is the date code of the part, not the part number.

 

[Northwinds]

I don't see any part number unless it's on the base, that's the only marking visable on the sides and all I see is AC on the top

The NTE bridge is definitely a replacement. The plastic case is a dead give away for an under rated bridge. Probably blew because of (too low of a) voltage rating however.

I tried unscrewing the phillips head but it only comes off so far and I did not want to risk messing something up in the tranny?

bad self tapper....reef it outta there...

Ok, it's out, no part number on the base

 

[laatsch55]

Not real proud of it were they??

 

[Northwinds]

Well they did brag "assembled in China" on one side...

And then stops or just spins?

Hoping the PO did not put too long a screw in there and jammed it into the windings of the transformer. Well your fuse test should tell you that.

 

[laatsch55]

Whoopee....not you Joe..Ron...

Probably a knock off NTE sold on Ebay

SHOCKING!!!!
