A technician is testing a pedal mounted brake switch with a voltmeter. When the brake pedal is depressed, the switch is receiving 12 volts, but no voltage is coming out. Technician A says with the brake pedal depressed there should be voltage present at both ends of the brake switch. Technician B says this condition indicates that there is an open in this brake switch. Who is correct?
Technician A
Technician B
Both
Neither
The dome light in a vehicle flickers on and off with the switch in the ON position. The MOST likely cause of this problem is:
A short to ground between the power source and the dome light.
An open in the wire leading from the power source to the dome light.
A loose connection between the power source and the dome light.
A burned out dome light bulb
A technician replaces a blown fuse in a dome light circuit and the element in the fuse melts immediately. Technician A says if a dome light keeps blowing fuses to check for a short to ground. Technician B says resistance in this circuit has increased current flow. Who is correct?
Tech A
Tech B
Both
Neither
