Fuel Test
The Black amps probe
will need to be connected
to the wire that supplies
battery power to the fuel
pump. Energize the pump to read
RPM and Amps, or RPM and AC Peak
Amps. When the pump is running,
the amperage must read as a positive
number or your Fuel Pump RPM will
not be correct, or stable.
If you are not able to read the RPM
confirm you are on the correct wire
and have the correct number of
commutators selected. The RANGE
key cycles through the commutator
settings. Most pumps have 6 or 8 communtators. Consult a
technical information source for the correct commutator count.
Each time the RANGE key is pressed the number of commutators
selected is advanced and displayed briefly on the upper display
preceded by an ‘r’.
Pressing the FUEL key alternates between viewing the DC and
AC amps readings on the lower display while the RPM is shown
on the upper display.
