INSPECTION
1.
INSPECTING THE RESISTANCE
(1)
Using a 1,000V megohmmeter, measure the insulation resistance
between either of the 2 terminals (no polarity) to which the injector
harness is connected and the upper body of the injector.
! CAUTION
Never measure between the terminals, or the injector will be dam-
aged.
(2)
Using a circuit tester, measure the resistance between terminals.
(3)
The resistance values of (1) and (2) exceed the standard value,
replace the injector.
2.
CLEANING THE INJECTOR
(1)
Use clean clothes to remove sludge adhered to the terminal part and
its perimeter.
! CAUTION
•
Use clean clothes to wipe off sludge without using any deter-
gent.
•
Use of detergent causes it to penetrate, which may lead to elec-
tric failure.
3.
CLEANING THE INSIDE OF THE NOZZLE SEAT
(1)
If sludge sticks to the inside of the nozzle seat, spray a detergent over
it, wipe it off with a waste cloth, and wash it out with the detergent.
NOTICE
•
If sludge sticks hard to the inside of the nozzle seat, remove it
with brush and a detergent.
•
It is advisable to perform a contact check using red lead primer.
(2)
Make sure that the inside of the nozzle seat is free of sludge or foreign
matters.
