Wrong test voltages

[drteeth]

Hi,

My test voltages are all wrong.

With 9v applied, TP22 is 0.8v instead of 3.3, V1 is 0.432v instead of 0 and V2 is 0.481 instead of 1.66. I have not tested the other voltages.

If anybody would like any other voltage readings, just ask and I will be happy to oblige.

I have reflowed any bad looking soldering. The supplied R4 did not give a steady reading when checked for its value, so I got a couple of resistors from stock and put them in series for the correct value.

Has anybody have any ideas on how to trouble-shoot this?

Cheers

I think the next time I buy one of these items, I will not give a damn if it is a fake or not. What is the point of buying a genuine article for zero support?
At least a counterfeit item could not have worse support!!!!!!!!!!!!!!!!!!
