5V PS2 Board

Boards are not repairable.  Run it until it dies, could be tomorrow, could be five years from now.  When it does die have one of the Awesome MTH techs here on the forum repair/upgrade it for you.  GGG or Gunrunner and a few others.

I just want to correct my statement about the two capacitors. The larger one is black with a grayish blue strip running from top to bottom.  The is black and has a gold stripe that hides the black because of the way its mounted.

the capacitor that usually fails was the one marked  WINCAP THEY BULGE OUT THE TOP eventually they exploded or short and explode  !

The board set is one piece, but it has an aluminum heat sink attached to rectifier that is screwed to frame with two small screws.  It can be removed from chassis.  Make sure you have a new 9V battery or BCR if you choice to go that route and just operate it.  While the cap is one failure point, there are many others too.  IF it fails it fails.  Certainly if the cap is bulged and the engine still runs replace it or have it replaced.  But if not you can do just as much harm trying to remove it to replace it. My opinion, but I have seen plenty of engines dead for many other reasons and whether the cap cause the issue or is fallout from other problems is undetermined.  I have had engine with that cap blown that still started up?  Others dead with a good cap.  G

George is certainly correct, I have a box of around 25-30 bad 5V boards.  Some have caps bulged, others look just fine.  I will say that the large 330uf 35V cap is the most often one that I see dying, and if it's the WINCAP brand, it's even more likely.  I have about 10% luck in replacing that cap if the board is dead and that looks defective.  If the board still works, then I'm all for IMMEDIATELY replacing that cap, clearly it's not doing the board any good to attempt to run with a failed cap!

As far as replacing the 5V board set, run them until they drop.  For the Climax, it'll be interesting fitting the replacement in, that tender is pretty small.  I have that climax with the 5V board, I'm hoping the board outlasts me so I don't have to replace it.
