Intermittent And Poor Connection - Suzuki SY413 Service Manual

1. Check contact tension by inserting and removing just once
2. Check each terminal for bend and proper alignment

INTERMITTENT AND POOR CONNECTION

Most intermittents are caused by faulty electrical connections or
wiring. When a check for proper connection is requested in a diag-
nostic flow chart, perform careful check of suspect circuits for:
D Poor mating of connector halves, or terminals not fully seated in
the connector body (backed out).
D Dirt or corrosion on the terminals. The terminals must be clean
and free of any foreign material which could impede proper ter-
minal contact. However, cleaning the terminal with a sand paper
or the like is prohibited.
D Damaged connector body, exposing the terminals to moisture
and dirt, as well as not maintaining proper terminal orientation
with the component or mating connector.
D Improperly formed or damaged terminals.
Check each connector terminal in problem circuits carefully to
ensure good contact tension by using the corresponding mating
terminal included in the connector test adapter kit (special tool).
If contact tension is not enough, reform it to increase contact ten-
sion or replace.
D Poor terminal-to-wire connection.
Check each wire harness in problem circuits for poor connection
by shaking it by hand lightly. If any abnormal condition is found,
change the wire harness assembly or component parts with new
ones.
D Wire insulation which is rubbed through, causing an intermittent
short as the bare area touches other wiring or parts of the ve-
hicle.
D Wiring broken inside the insulation. This condition could cause
a continuity check to show a good circuit, but if only 1 or 2 strands
of a multi-strand-type wire are intact, resistance could be far too
high.
If any abnormality is found, repair or replace as a wire harness as-
sembly.
