K2 Voltage Problem Initial Check

[himself-2]

Finally got to the first Alignment and Test, Part 1 on my K2.
Upon power up the display reads E25.5 i.52 for the voltage display.  All the other initial menu driven checks are ok.  Can't find why the voltage is so high.  Checked both 5 and 8 volt regulators and thier ok.  RP1 and RP2 are not swapped.  Built the internal voltage probe and it didn't work either. Spent 3 hours troubleshooting so far.

Any one with an idea.

Stephen

Stephen,

Check your power supply voltage - if you are using a wall-wart, many of
those deliver much greater than their indicated voltage.

If you have less than 15 volts at the K2 input, that is likely OK, but
something more like 13.8 volts is preferred.

The higher voltage can also explain the high current draw.
