4.10.6 Using the Ohms setting on the multimeter, measure the resistance of
main winding 2 by measuring across the upper two terminals (c)
(yellow and red). On GP 2500A/GP 2600 models, measure across the
red and white wires. Also check the resistance of main winding 1 by
measuring across the two lower terminals (d) (black and green). On
GP 2500A/GP 2600 models, measure across the brown and blue
wires. Each generator size will have a different value. Check the chart
in the graphic for the correct values; use a tolerance of +0.5/-0.0 Ohm.
• If the correct resistance is not measured, the main windings are
bad; replace the stator.
• If the correct resistance is measured, continue.
4.10.7 Check each winding to ground. (Measure resistance between the
winding and the ground stud (x) of the stator. Measure both sides of
the winding.)
• If either winding has resistance to ground, it has failed.
• If both windings show no resistance to ground, they are OK.
