EZGO ITS Throttle Problems And Adjustments
Throttle Voltage Check With Alltrax Controllers
To verify that the Inductive Throttle Sensor (ITS) is working correctly with the Alltrax controller you will need to measure the throttle inputs voltage at the controller and also at the ITS throttle to make sure they have the same readings.
Make sure the cart is jacked up so you can run the wheels. Don't short between pins when doing measurements, you could damage the controller.
For Alltrax XCT, DCX & NCX controllers, you need to pull the 10 or 6 pin connector back just enough to expose the pins to measure them. Make sure not to short any of the pins. With the key On, tow run On and the F/R in forward position measure the voltage between the two throttle pins (see pictures below). You should see 10 volts. Press the Pedal down to the floor, full throttle and you should see 6 volts.
For Alltrax SR, SPM, SPB, AXE & NPX controllers, measure the voltage
between the two throttle pins (see pictures below) with the key on and the peddle depress just enough to active at the foot switch. You should hear the solenoid close at this time and have a lit LED light. You
should see 10 volts on the throttle pins. Press the Pedal down to the floor, full throttle
and you should see 6 volts.
Out of range
When measuring at the controller, if you are measuring 12 volts it is typically a bad ITS unit, and if you get 14 volts there is often a broken wire running to the throttle.
SPM-***** EZ Pins
SPM***** EZ controllers the throttle pins are 2 & 3 on the left set, or 1 & 2 on the smaller pins on the right. Choose one set or the other to test. Note that for SPM controllers and ITS throttles you must use the included noise filter.
