measuring probe against the measurement point
and the black measuring probe against a grounding
point (e.g. negative battery terminal) and read off the
voltage on the multimeter display.
Measure resistance:
Use a multimeter in resistance mode. Hold the red
measuring probes on the measurement points and
read off the value on the multimeter display.
On contact, the value should be low (<1 Ohm).
On broken contact, the value should be high
(>500 Ohm).

• Cable breaks
• Worn cable sheaths
• Cable fastening in terminals
