Preparations On The Vehicle: Measurement: Notes

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2004 Porsche Boxster, 2003 Porsche Boxster, 2002 Porsche Boxster, 2001 Porsche Boxster, and 2000 Porsche Boxster. However, it is still accessible from the selected car via links, so may be relevant.

Select a measuring range which ensures that the pointer of the instrument is in the upper third of the scale, as far as possible. Switch over measuring range without interruption. Read off the measuring values after the waiting period specified in the table.
Do not switch on any electrical loads (opening the central locking system) during measurement.

NOTE:

If the value of the closed-circuit current is higher than the value determined in the table, the cause must be established systematically.
The recommended troubleshooting procedure: With the measuring instrument connected, remove the fuse of terminal 30 and the relays one after the other. Observe the display values of the measuring instrument when removing in order to recognize a reduction in current.
After troubleshooting, screw the ground strap back onto the body in the proper manner.
The measured values could vary by approx. 20%.
The values listed in the table depend on the condition of the battery, the room temperature, and the engine temperature.
