6.2 TRoUBlESHooTING - CoNSolE PoWER ISSUES
PoSSIBlE CAUSES:
1) The console is damaged or the console cable is not connected properly.
2) Poor connection to the terminals on the lower board.
3) The lower board is damaged.
4) The ECB is damaged.
SolUTIoN
1) Check the console cable connections at the console and lower board.
2) Unplug the console cable at the console. Use a multi-meter to check if the voltage between the 1 (VCC) and 7 (Ground) pins of the console cable is
greater than 12 (figure A).
a. If voltage is greater than 12, replace the console.
3) Unplug the ECB wiring harness from the lower board and pedal the machine. Use a multi-meter to check to see if the voltage from the ECB is variable
(voltage should vary depending on the RPM used).
a. If the voltage is variable, replace the lower board.
b. If the voltage is not variable, replace the ECB.
c. If the issue is still not resolved after replacing the ECB and lower board, replace the console cable.
