could be a sensor or relay
To start I would check the connections on the receptacle. Next change the receptacle. It sounds to me there is a corrosion problem here...pkazsr
test light or volt meter
The "bus" is the communication system for the computers. No bus means the system is not working. You need a scan tool, wiring diagrams, and a volt meter to diagnose.The "bus" is the communication system for the computers. No bus means the system is not working.

With a volt meter or a test light ,it also might be a fuse
To Troubleshoot simply means to diagnose the cause of a malfunction. an example would be if your taillights weren't working. using a volt meter or test light you could test to see if the fuse had blown, you had an open wire, or both tail light bulbs were bad.
The volt.
Battery keeps running down when you are driving. Your battery light should be on if the alternator is bad. Check the voltage at the battery with a digital DC volt meter set to the 20 volt scale. You should read from 13.5 to 15.5 volts with the engine running at idle. If not the alternator is suspect.
use an Ohm meter to check the bulb for continuity and a volt meter to make sure that it is getting voltage in order to light up
That would be a ( 12 volt battery ) in the engine compartment of a 1998 Ford Explorer
Volts
Parallel
It depends on what you want to monitor. Most commonly the volt meter is connected in parallel with the battery or the alternator.
