a. Hot – Touch a meter lead to the Hot/Narrow blade of the plug
and the other meter lead to the Black lead connection on the
Power Supply (1) - Continuity
b. Neutral – Touch a meter lead to the Neutral/Wide blade of the
plug and the other meter lead to the White lead connection on
the Power Supply (2) - Continuity
12
c. Continuity in both means the problem is not in the power cord or
harness. Go to 5.
d. No continuity in one or the other or both means the problem is in
either the cord, grip connections or the harness (Go to 3)
3. Power Cord
a. Remove the grip from the handle tube and open it
b. If there are any loose wires reconnect them and perform the
appropriate test (2a or b).
c. If the wires are properly connected, then they are not the
problem
d. Remove the wire nut from the two Black leads and check the
cord for continuity between the Hot/Narrow plug blade and the
Black cord lead at the grip.
e. Remove the wire nut from the two White leads& one and check
the cord for continuity between the Neutral/Wide plug blade plug
blade and the White cord lead at the grip.
f. If d & e both have continuity then the cord is not the problem.
Go to 4.
4. Harness
a. Hot – Touch a meter lead to the Black harness lead in the grip
and the other meter lead to the Black lead connection on the
Power Supply (1)
b. Neutral – Touch a meter lead to the White harness lead in the
grip and the other meter lead to the White lead connection on
the Power Supply (2)
c. If a & b both have continuity then the harness is not the
problem. Go to 5.
5. Power Switch – Continuity Ω
a. This check requires either two people or a lot of finger
coordination. At least there are test points.
