Refer to Figure 5.4.14.1, Figure 6.3.17.4, and use a high-impedance (preferably digital)
volt/ohmmeter (DVM) to make the following checks.
WARNING
THE ENGINE SHOULD NOT BE RUNNING AND THE IGNITION SWITCHES SHOULD BE
OFF!
(a) Turn all switches off. Use the lowest resistance scale on the DVM. Check the
resistance between the battery negative (-) terminal and the engine case.
Measurements over 0.5 Ohm in either cause should be investigated. If this is the
case, check the engine ground strap and the battery ground strap for loose or
contaminated connections, broken conductors or bad crimp joints. If these
measurements are less than 0.5 Ohm, any of these points may be used as
reference (-) for the following measurements.
(b) Turn on the master switch. Measure the voltage on the battery bus and on pin +
of the regulator. The voltages should be equal, within 0.2 volts. A difference of
more than 0.2 volts may be caused by a bad breaker.
(c) Try a 5 pound pull test on all crimp joints and make sure that the terminals are
crimped on the wire, not the insulation.
(d) Troubleshoot systems to determine the root cause of the problem.
