Short Circuit
Short Circuit
A short circuit happens when the current bypasses part of the normal curcuit. This bypassing is usually caused by wires touching, salt water in or on a
component such as a switch or a connector, or solder melting and bridging conductors in a component.
Grounded Circuit
Grounded Circuit
Grounded Circuit
A grounded circuit is like a short circuit but the current flows directly into a ground circuit that is not part of the original circuit. This may be caused by a
wire rubbing against the frame or body. Sometimes a wire will break and fall against metal that ia connectod electrically to the ground side of the voltage
supply. A grounded circuit may also be caused by deposits of oil, dirt, or moisture around connections or terminals, which provide a good path to
ground.
Intermittents and Poor Connections
*** FOR ADDITIONAL INFORMATION NOT INCLUDED HERE, REFER TO TSB# 9282 DATED SEPTEMBER, 1991 ***
Most intermittents are usually caused by faulty electrical connections or wiring, although occasionally a sticking relay, solenoid, or loose ground
point can be a problem.
