Montvale, NJ January 1985 Technical Dept.
SUBJECT: Vehicle Will Not Start
MODEL: 325e
Complaint: Vehicle will not start, although the starter will engage, the instrument panel lights are on, and other electrical items can be operated.
Cause: Possible cause could be no voltage present at the battery junction block at the
6 sq.mm. black wire (located in the engine compartment).
Result: No electrical current to the DME main relay and fuel pump.
Correction: The 6 sq.mm. black wire from the battery (in the trunk) to the battery junction block contains a 50 ampere rated fusible link. The fusible link is located approximately 6 inches from the battery + (positive) terminal inside the harness covering.
Open the harness and inspect the fusible link. If the fusible link is "open", use an ohmmeter on the vehicle side of the link to determine if a "short to ground" caused the fusible link to "open".
Replace the fusible link (P/N 12 41 1 706 111) if:
a) "short to ground" is detected. Locate and correct the short before replacing the fusible link.
b) no "short to ground" is detected. Fusible link "open" may have been due to a momentary overload.
