Checked the reed switch, its got power. Bypassed the floor micro switch, no change, its fine too. I'm tempted to install my stock solenoid and see if I can rule that out as well. |

Re: Another No-Go Ezgo, here's some numbers...
Okay, lets try move to a different test point. Connect the voltmeter between the B- and M- terminals on the controller.
Push the pedal just far enough for the solenoid to click and the voltmeter should read FULL pack voltage. If not, there is a problem in the cables/connections, F/R switch contacts or motor. (Maybe not the motor, since you swapped it out) If you do get full pack voltage, slowly push the pedal to the floor and the voltage ought to smoothly decrease to zero. If not, check the throttle (ITS) signal. Should be 10V between black and white wire with pedal up and 6V with pedal down. If you have a valid throttle signal to the controller and full pack voltage between B- and M-, but it doesn't drop to zero when pedal is pushed, the controller is not doing what it is being told to do, so it is bad. If the voltage between B- and M- does drop to zero whem the pedal is floored, the motor ought to be turning or smoking. |

Voltage reading between B- and M- is 48.5V, with slight depression of pedal (just enough to get solenoid to click) pack goes to 50.9 (which is current pack voltage at battery terminals), when peddle is then depressed to the floor the reading stays at 50.9V ITS Signal: -pedal non-depressed probes on Black and white wires at the controller .67V -Pedal depressed just enough for solenoid to click 9.03V -pedal depressed to floor 5.39V Soooooo,,,,,, Controller? If so what are options? Send back to Altrax to fix? Thanks again guys for all the help:thumb up: So much appreciated! |

Re: Another No-Go Ezgo, here's some numbers...
The LED flashes 4 times and goes to steady green, the voltage between B- and M- stays the same from pedal at solenoid click to pedal on floor, while ITS signal varies from about 10V down to about 6V. That indicates the controller is bad.
An AXE controller is filled with a potting compound, so it isn't repairable, but contact Alltrax with the serial number. If it is under warranty, they will replace it. |

Thanks again for all your help JohnnieB, your expertise is much appreciated. If they don't replace it under warranty, any suggestions on a replacement? This buggy is used as a hunting buggy, off road, with hills. I'd like something indestructible..... if such a thing exists |

If you are running a 6 X 8V, you might get away with leaving one of them out for a 40V system, but the is going to imbalance the pack something awful. |

Re: Another No-Go Ezgo, here's some numbers...
If I wanted to make sure it was my controller causing the problem, could I take a battery out of the loop (yes 6 x 8Volt) and go to 40V or 32V? I would do this while the cart is jacked up just to see if it works? If so, would I have to use the stock solenoid as well?
