This TSB article is being republished in its entirety to update the applicable model years.
Electrical system concerns that are due to diode failure may be serviced with an approved Ford service diode. Some electrical diodes used in early
production vehicles are color coded for the purpose of size identification while others are stamped with a manufacture number. All Ford service diodes
and current production diodes are identified by manufacture number.
If service is required, refer to the appropriate model/year Electrical and Vacuum Troubleshooting Manual (EVTM) to determine the size and location of
the diode(s). Refer to the following Electrical Diode Application Chart for the correct service part number.
IF THE DIODE REQUIRING REPLACEMENT DOES NOT HAVE THE SAME RATING AS LISTED IN THE APPLICATION CHART, USE
THE NEXT HIGHER RATED DIODE.
