Using Current Probes to Diagnose Driveability Dilemmas
current probes have been around for years, even the venerable VAT40
charging/starting systems tester had one! Current probes use induction and
“clamp” around a wire which gives us a non-intrusive method of viewing
current flow in a circuit. These tools are not just for checking starting and
charging system anymore. Coupling these tools with the modern DSO, or lab
scope, they are incredibly powerful diagnostic instruments! Current probes
can be used for checking engine mechanical integrity, ignition and injection
system operation, active wheel speed sensors, shorted engine sensors,
parasitic draws and even for network diagnostics. Current probe tooling
options and techniques will be discussed in this class. Case studies will
support some interesting approaches to some unique diagnostic dilemmas. One
is only limited by ones’ imagination and creativity when it comes to this
affordable and often underappreciated tool.
