INVERTER (WITH EL TYPE CLUSTER)
The inverter is located in the instrument cluster and it converts the direct current (DC) into the alternating current (AC).

Illumination power applied to inverter in the cluster is converted into the alternating current (AC), which is supplied EL (Electroluminescent Lamp) sheets to be illuminated.




1. Remove the front cover from the cluster and disconnect wire lead connector from EL sheet.




2. Apply battery voltage (DC 13.5 V) to the inverter in the cluster and measure the output voltage between terminal 1 and 2.




3. Also measure the output frequency between the terminals.




4. If the value is not as shown in the table, replace the inverter.

NOTE: If the Inverter is normal, connect the EL and inverter, supply power to the cluster, and check the EL illuminates at the dark.
If EL illumination is too dark, should be replaced.
