ELECTRICAL SYSTEM 16-75
Meter, Gauge, Indicator Unit
Trip A/B Meter Check
•
Check the trip A or B meters by the same way as the
speedometer check.
If value indicated in the trip A/B meters is not added, re-
place the meter unit.
•
Check that when the right button is pushed for more than
2 seconds, the figure display turns to 0.0.
If the figure display does not indicate 0.0, replace the me-
ter assembly.
NOTE
○
The input frequency of the oscillator adds the integrated
value of the odometer.
○
The integrated value of the odometer cannot be reset.
Tachometer Check
•
Connect the 12 V battery and terminals in the same man-
ner as specified in the “Liquid Crystal Display (LCD) Seg-
ments Check”.
•
The revolutions per minute (rpm) equivalent to the input
frequency is indicated in the oscillator [A] if the square
wave (illustrated as shown) would be input into the termi-
nal [6].
○
Indicates approximately 6 000 rpm in case the input fre-
quency would be approximately 200 Hz.
•
If the oscillator is not available, the tachometer can be
checked as follows.
○
Connect the 12 V battery and terminals in the same man-
ner as specified in the "Liquid Crystal Display (LCD) Seg-
ments Check".
○
When the terminals are connected, the tachometer goes
and disappears from minimum to the maximum reading
momentarily. It goes again, and then the tachometer dis-
appears.
If the tachometer segments function does not work, re-
place the meter assembly.
○
Using the insulated auxiliary lead, quickly open and con-
nect the terminal [2] to the terminal [6] repeatedly.
○
Then the tachometer segments [A] should flick [B].
If the hand does not flick, replace the meter assembly.
Fuel Level Gauge Check
•
Connect the 12 V battery and terminals in the same man-
ner way as specified in the “Liquid Crystal Display (LCD)
Segments Check”.
•
Connect the variable rheostat [A] to the terminal [16] as
shown.
