No ripple just voltage is too high. Any ideas?

Adding a plugin dropped the voltage to 13.2V

This is normal behavior.

The 11.4V is an unregulated supply, and is
expected to be high when unloaded, and to be
about 11.4V when fully loaded, and at the
minimum power line voltage.

Hi Lop Pol,

If all the voltages are proportionately high then the Voltage jumper on the back panel or inside the TM504 (it's in a different place on each mainframe model) is set too low for your mains voltage. Check your mains voltage with an RMS meter and set the jumper to LOW, MED, or HIGH accordingly.

If only the 11.4V is high the jumper setting isn't the cause.
