SUBJECT: NO CRANK CONDITION
MODELS AFFECTED: 1986-87 PARK AVENUE, ELECTRA, LESABRE
If a condition of no crank (with battery fully charged) occurs, it may be caused by a broken terminal on the purple starter solenoid lead. This condition may have been caused by one or more of the following:
a. No slack (loop) in starter lead to harness prior to entry in its protective sleeve (Item 1, Illustration).
b. Wiring harness assembly mispositioned either direction (side to side) in its protective sleeve (Item 2, Illustration).
c. Terminal end was slightly bent upon installation.
CORRECTION
a. Replace starter solenoid pigtail with kit, Part Number 12083018 which also includes one (1) splice connector, 05297428, and an instruction sheet. Refer to 1987 Chassis Service Manual, Electrical Section 8A-5-2 for repair technique.
b. Be sure pigtail terminal doesn't get bent (has to be 90~ in relation to solenoid).
c. Be sure pigtail has loop (for slack) prior to entry into protective sleeve. Reposition harness in protective sleeve, if necessary (Item 2) (Must not contact accessory belt).
It is of utmost importance that the wire has sufficient slack because of the engine rising in it's front mount during certain torque conditions.
