Cadillac Service Information Manuals sometime advise technicians to check for intermittent open circuits. This bulletin contains a procedure to inspect Micro-Pack female terminals. The female terminal may be oversized in the internal diameter causing intermittent open or high resistance connections.
FIGURE 1 - MICRO-PACK TERMINAL:
To check a Micro-Pack terminal, first visually inspect the terminal using a flashlight, refer to Figure 1. Check to be sure that the terminal is properly retained in the connector body and check the crimp and wire retention. After visual inspection, use a .95 mm pin gage to check the terminal inside diameter. Insert the gage into the front of the terminal.
The female terminal should grip the pin gage securely.
If the gage will drop through the terminal under its own weight, or if there is only a light drag on the gage from the terminal, the terminal should be repaired or replaced.
If the female terminal does not grip properly, replace the terminal with P/N 12020757. General directions on wiring repair and terminal replacement are shown in section 8A of the Service Information Manual.
NOTE: Never front probe a Micro-Pack terminal with anything other than a .95 mm pin gage or the connector test adapter kit (tool J-35616). Front probing can spread out the terminal and cause an intermittent open circuit.
