Component Tests: Notes
WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Before carrying out maintenance on the starting system, disconnect the battery ground cable from the frame to completely isolate the starter from the dual frame-mounted batteries. Failure to follow this instruction may result in serious personal injury.
Always make the 73III Automotive Meter connections at the component terminal rather than at the wiring end connector. Making a connection at the wiring end connector could result in false readings because the meter will not pick up a high resistance between the wiring connector and the component.
