Jumper cap malfunction protection – no jumper

From Service Manual 643924, p.16:

1.Verify jumper cap is present and correctly inserted on mainboard; replace if damaged.

2.Measure control board supply voltage at the test points. Expected: 12 VDC and 5 VDC; a drop below 4.75 VDC on the logic rail points to a failed onboard regulator.

3.Inspect all connectors on the main control for corrosion, thermal stress, or backed-out pins. Reseat each connector with the power disconnected.
