Subject: Passive Belt System Power Circuit
Modification

Application: 1987-89 900 Models with Passive Belt Systems


The passive belt system used on certain 1987-89 900 models draws a minor amount of electrical current when the car is parked. In certain cases this current draw may be sufficient to completely discharge the battery if the car has not been driven for a week or more, depending on the total current draw of all systems in the car and the condition of the battery. To remedy such cases where the minor current draw results in battery discharge, a kit has been developed which includes a time delay relay to cut off power to the passive belt system approximately 10 minutes after switching off the ignition.

The wiring modifications included in the kit will not alter the mechanical operation of the passive belt system. This kit will not remedy mechanical problems. Any mechanical malfunctions should be remedied before installing the kit.

The kit includes two relays that supply power to the passive belt system in two different ways. When the ignition key is switched on, power is supplied via the time delay relay during the time the ignition is on and for approximately 10 minutes afterward. If the ignition is not switched on, power will be supplied via the other relay whenever either front door is opened. This power circuit is disconnected when the door is closed.

Installation Instructions

Installation instructions are included with the kit and are attached to this PSI. Note, however, the following additional steps that are not included in the instructions.

After step 17: Connect one of the two diodes in line with the orange wires, noting that the spade terminals on the diode are different sizes and match the connectors on the wires.

After step 18: Connect the other diode in line with the white wires, noting that the spade terminals on the diode are different sizes and match the connectors on the wires. Refer to the wiring diagram included in the instructions for further clarification concerning the location of the two diodes in the revised wiring.
