Circuit ldentification for In'Line and Fuse Box Connectors
tuse the chart (on page 204, sample below) to help diagnose multiple symptoms in separate
circuits which could be caused by a single problem in a connect,oishared by those circuits'
Here's how that chart could help you find such a problem:
1. Pick one of the multiple symptoms and look up the schematic for that circuit'
2. Make a list of all in-lrne and fuse box connectors in that schematic (include page numbers).
3. Then, in the chart, look up each connector on your list to see if circuits related to the other
symptoms run through one of them. lf they do, inspect that connector for the problem.
Example: The horn, A,/C, and the right headlight don't work. List all in-line and fuse box
connectors in the horn circuit and then check the chart (sample below). You find that C211 is
common to the A,/C circuit and the headlight circuit, so you inspect c211 and find the problem:
bent terminals.
