NOTE: Latching is a common term used to describe a vehicle’s
computer system turning on and staying on for extended periods
of time when a car is at rest. Latching can lead to parasitic draw
and drained batteries.
m. When testing is complete, follow reverse instructions from
section “i” back to prevent memory loss to the vehicle’s
computer system. Be sure to reapply memory savers and other
protective devices.
n. To find and repair the problem in a specific circuit, follow
standard procedures for reconnecting the battery. Connect the
PULSAR
™ directly into the problematic circuit by using the
appropriate adapter and begin troubleshooting.
NOTE: If excessive current draw is not found, there still may be a
problem with a momentary computer check. This may occur
during the time the car is at rest. To be sure this is not the
problem the PULSAR
™ can be left connected for an extended
period of time on “Peak Hold”. Return to the car later to verify the
maximum amperage drawn.
15. TROUBLESHOOTING SHORT CIRCUITS WITH
THE PULSAR
™ :
The PULSAR ™ allows you to safely send current into a circuit at a limit of
your choice while viewing the current draw. The versatility of the
Pulsar’s adjustable current limiter lets you set a desired amperage rating
while chasing down steady or intermittent overload and short conditions
(1 - 50 Amps).
a. Select Automatic Mode or Manual Mode. (See Sections 4 & 5)
b. Select the proper adapter and connect in line with the fuse box
or circuit.
c. Dial in the desired Amp Limit, up to 50 amps.
d. Engage the PULSAR ™ and observe current draw. In Automatic
mode, you are free to move about the vehicle, shake testing
wiring harnesses and exploring the circuit for the source of
intermittent shorts or overloads. While you are looking for
problems, the internal computer of the PULSAR
™ continually
monitors the circuit for an overloaded or short circuit condition.
If a short exists, the PULSAR
™ turns off the circuit in 0.05
seconds and enters PULS mode (See section 11). Once the
source of the overload is removed, the PULSAR
™ resumes
supplying constant power. While troubleshooting, this allows you
to repeatedly investigate the cause of a short circuit until you
locate the source of the problem.
16. BENCH TESTING WITH THE PULSAR ™ :
Bench testing is a common practice where an electrical component is
isolated from the rest of the circuit and tested for proper operation. The
most common examples are light bulbs, horns, fans and electric motors.
The PULSAR
™ allows you to safely send power to this equipment, either
manually or automatically, while viewing current draw.
