WPC89 WH20 Power Board issue

[videoguys]

Hi guys,

Having a small issue with my white water im in the middle of restoring. Im not Getting 20V AC from J105, So there seem not enough power to drive the Topper lights chaser board. Should i be looking at replacing BR4 and C11? Any help would be appreciated. Mike

I would start by looking first at the plugs and header pins of j101 and j102. I have repaired more power and reset problems by replacing those parts than bridges and caps
