• Check that cables are not touching each other or other objects.
• Continuity test and check each cable for defects, i.e., fraying,
splits, corrosion, etc. Repair and/or replace accordingly.
• Check that each cable is tight and torqued to specifications. See
mechanical installation detail plate drawing on page 54.
• Using VOM, check solenoid for proper opertaion, i.e., solenoid
opens and closes with the control switch. If it does not - replace
solenoid.
• Using VOM (volt ohm meter), check wires for proper voltage -
12VDC requires minimum of 9.0VDC; 24VDC requires minimum
of 18.0VDC.
Notes:
If problems still exists, replace solenoid and recheck all connections and batteries.
It is NOT recommended to put RTV silicone or epoxy over the solenoid connections. Use a suitable battery terminal
sealer spray. Also see Section 5 Maintenance, heading “Lubricants” on page 45.
