Suzuki GSX-R 1000 Service Manual: Voltage check
If voltage is supplied to the circuit being checked, voltage check can be used as circuit check.
- With all connectors/couplers connected and voltage applied to the circuit being checked, measure voltage between each terminal and body ground.
- If measurements were taken as shown in the figure and results were listed in the following, it means that the circuit is open between terminals “a” and “b”.
Voltage between
“a” and body ground: approx. 5 V
“b” and body ground: approx. 5 V
“c” and body ground: 0 V
- Also, if measured values are as listed following, a resistance (abnormality) exists which causes the voltage drop in the circuit between terminals “a” and “b”.
Voltage between
“a” and body ground: approx. 5 V
“b” and body ground: approx. 5 V – 2 v voltage
drop
“c” and body ground: 3 v – 2 v voltage drop
Continuity check
Measure resistance across coupler “b” (between “a”
and “c” in figure).
If no continuity is indicated (infinity or over limit), the
circuit is open between terminals “a” and “c”.

Short circuit check (wire harness to ground)
Disconnect the negative (–) cable from the battery.
Disconnect the connectors/couplers at both ends of
the circuit to be checked.
