NO START OR NO ENGINE CRANK (MAY BE BROKEN 'S' TERMINAL

NO CRANK CONDITION

VEHICLES AFFECTED: 1986-87 C AND H MODELS ------------------

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 1, 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 BA-5-2 for repair technique.

b. Be sure pigtail terminal doesn't get bent (has to be 90 degrees 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 its front mount during certain torque conditions.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
