Save Time on Electrical Diagnostics
T
racking down electrical problems can be very time consuming
without the proper diagnostic tools. Power Probe circuit testers have
a unique combination of functions that can save valuable diagnostic
time when trouble shooting electrical problems.
While recently diagnosing a car that had no parking or taillights, a
blown fuse was quickly found by simply probing the test points on the
fuse itself. If the fuse is intact, the readings should be the same on both
fuse test points. In this case, the Power Probe indicated for B+ power on
one side of the fuse and indicated for ground on the opposite side of the
fuse, which means the fuse was open and needs to be replaced. The open
fuse shows power to the fuse box on one side only, while a good fuse will
show the same readings on both fuse test points.
But now, before replacing the fuse (and possibly blowing it again) you
can check the circuit for shorts by quickly applying power to the side of
the fuse that indicates ground. Connect the probe tip directly to the fuse
test point on the side that shows ground and then press the power/ground
rocker switch forward to apply power directly to the fuse. If there is still a
shorted condition on the circuit it will trip the Power Probe circuit breaker.
If you apply power and the circuit breaker does not trip, then the circuit
has no short and you can safely replace the fuse.
In our case the circuit breaker did trip, so we knew we had a short
somewhere in the park light circuit. But where to start looking? The parking light circuit goes to every corner of the vehicle and even some interior
light circuits. On this particular vehicle many of the individual lights are
powered together through a common splice pack, so we could easily unplug
the splice connector to separate the different light circuits and then use the
Power Probe to supply power to each individual light circuit until we found
the one that trips the circuit breaker. For this car we found the short was on
the lighting circuit leg that went to the center console and illuminated the
shifter, etc. Using the proven time-saving testing capabilities of the Power
Probe, the problem was quickly found and corrected in just a few minutes.
