Hi sgraf, Welcome to EasyEDA. You have to realise that all voltages measured using a voltage probe are single ended voltages measured with respect to the ground in the simulation. If you move the ground to the lower end of R2 then the voltage at the top end of R2 will look right but the voltage at the top end of V1, probed by Vs2, will then look wrong. With the ground at the low end of V1, you need to measure the voltage *across* the load resistor, R2. There are several ways to do this but possibly the easiest is to use the EasyEDA Voltmeter symbol from the EasyEDA Libs. Another way is to use an `E` source (a Voltage Controlled Voltage Source or VCVS) with a gain of 1 (the default in the EasyEDA Libs). Connect the `+` input to the top end of R2 and the `-` input to the bottom end of R2 then ground the `-` side of the output to ground and put you probe on the `+` side of the output. I have modified your circuit and shown both options: <https://easyeda.com/file_view_fullbridgerectifier01_beEQOnljF.htm> For more, see: <https://easyeda.com/file_view_Probing-voltages-01_Il5nTDx3z.htm> <https://easyeda.com/file_view_Probing-voltages-02_PYWwIiSPN.htm> <https://easyeda.com/file_view_Probing-currents-01_ZzsK2Wewq.htm> <https://easyeda.com/file_view_Using-the-probe-command_db5mgyQ8q.htm> Please note: the easiest way to share a file is to use the > **Share > Active file > URL** option.
