Speed Control Electrical Test
Electronic speed control systems may be tested using two different methods. One involves use of a DRB. If this test method is desired.The other test method uses a volt/ohmmeter. The volt/ohm meter method is described in the following tests.
Speed Control Circuit:
CAUTION: When test probing for voltage or continuity at electrical connectors, care must be taken not to damage connector, terminals, or seals. If these components are damaged, intermittent or complete system failure may occur.
When electrical connections are removed, corrosion should be removed from electrical terminals and a light coating of Mopar Multi-Purpose Grease, or equivalent, applied. Inspect connectors for damage terminals.
A poor connection can cause a complete or intermittent malfunction and is also the only connection in the circuit, that can not be tested. For this reason a loose connection may be misdiagnosed as a component malfunction.
