Hi everyone.
My name is Steve & I work for a company London as a repair engineer.
A customer brought in his beolink 7000 charger PCB for repair as it doesn't charge but he only brought the PCB in. When plugged in to the mains I get a voltage reading of roughly 7 VAC on two of the transformer terminals but no DC output. I've tested the diodes and they are all OK.
I have 2 questions :
`1. Would the device need to be in 1 piece and have the battery plugged in for a DC voltage to register on its output.
2. Anyone else had a problem with these?
I've included a pic of it.
Any help appreciated,
Thanks,
Steve.S

I have only had 1 of these that did not charge, That was a bad solder point at the bottom of the PCB below the transformer.
First is to check all solderpoints, then you can continue. At the connector to the BL7000 there will always be voltage to measure, also with no remote.
From middle contact and to the left and right, you should measure 7.8 and 9.5v approx.
There is also a resistor in the housing between 2 of the 3 points, cannot remember which, but you need the housing to see this.
