Right Motor Disconnected - Sunrise Medical Quickie S-11 Service Manual

Understanding VSI Controller Diagnostics Codes (cont.)
3.4 Four Bars- Right Motor Disconnected
The right hand motor has a bad connection. Check the connections to the right hand module.
Test Right Motor Open
Check that the batteries are fully charged and in good
condition, and check all cables and connections. Check
the connections to the right motor, look for a loose or dam-
aged connector. Remove the 9-pin Beau plug and check
the resistance across pin 1 and pin 2 as shown on (figure
A3.4.1). If the meter reads between 0 to 1.5 ohms, then
replace the controller.
If the meter reads between 0 and 1.5 ohms, then replace the controller.
Otherwise, check both brushes on the right motor. (Refer to
Section 4 Step 9 of this Service Manual for easiest access).
Ensure that the brushes are not excessively worn, (replace
as required). Top access for Motor brush shown in (figure
A3.4.2) (requires shroud removal).
Use the meter to check the resistance across the two
bottom contacts of the thicker wires on the 4-pin motor
connector as shown in (figure A3.4.3). If the meter reads
between 0 to 1.5 ohms, then replace the main harness. If
none of the above corrects the problem, replace the right
motor.
If the meter reads between 0 and 1.5 ohms, then replace the main harness. If this does not correct the prob-
lem, then replace the right motor.
