Door Safety Warning Lights - Stay ON W/Doors Closed
85jaguar01DATE . . . APRIL, 1985
NUMBER . . . J85/35
MODEL: XJ6 & VDP
SUBJECT: DOOR SAFETY WARNING LIGHTS
KEY POINTS: MODIFICATION TO PRESENT FEEDBACK CIRCUIT
In the winter periods where the ambient temperatures are particularly severe, it is possible for the electric antenna mast to freeze in the mid position causing the main circuit fuse #3 to blow through the aerial operation being impaired.
Should this occur, it is possible for the door safety warning lights to illuminate with the doors closed, and in some cases, due to the problem going unnoticed, can result in the battery discharging when the vehicle is parked.
The cause has been traced to a feedback circuit developing through the interior light circuit which is also protected by the same fuse link, Fuse #3 - main fuse box.
To prevent this involuntary illumination and possible battery discharge, modified bulkhead harnesses incorporating diode protection on the interior light circuit will shortly be introduced.
Should this problem be encountered on vehicles already in service, the following modification may be implemented.
PARTS REQUIRED
1 off Lucar Connector P/N GHF 2051 Code A
1 off Lucar Connector P/N GHF 2060 Code B
2 off Lucar Insulation Sleeve P/N GHF 2151 Code C
1 off Diode P/N AAU 5034 Code D

MODIFICATION PROCEDURE
1. Disconnect the battery.
2. Remove the passenger side "A" post lower trim panel to expose the lower bulkhead/door harness (see Fig. 1) . Passenger side RHD is shown, LHD is symmetrically opposite.
3. Locate the interior door switch - purple/white (PW) cable and cut.
FIGURE 2:
4. Fit insulation sleeves (C, Fig. 2) and crimp/solder Lucas connector (A and B, Fig.2), to the purple/white (PW) cable. Connect diode unit (D, Fig.2) in circuit and strap or tape to the harness.
5. Refit the "A" post lower trim panel and reconnect the battery.
If the above work is performed as a warranty, enter the bulletin number, J85/36, as the causal part number with a defect code of 93.
The labor allowance and repair operation is 86.91.03, Modify Door Warning Lights, 0.45 hrs.
