Re: Hunting Cart down
To test the S1 and S2 cables swap them and see if the problem follows one of the cables or remains the same.

Re: Hunting Cart down
When swapping the S1 and S2 cable forward is good and reverse shudders.
Pack Voltage 52.7V B- to M- 52.6V Main solenoid test good Rev Contactor: Reverse side,S1 49.1V on power side/49.9V on motor side when pedal is pushed Forward side,S2 49.0V on power side/ .002V on motor side I replaced the S2 cable with no change When going in forward there is a HUGE Amp draw from the motor |

Re: Hunting Cart down
Need four voltage measurements:
1. S1 to S2 in with F/R switch in F and pedal on floor. 2. S1 to S2 in with F/R switch in R and pedal on floor. 3. A1 to A2 in with F/R switch in F and pedal on floor. 4. A1 to A2 in with F/R switch in F and pedal on floor. Voltages in 1 & 2 ought to be same except for polarity. Voltages in 3 & 4 ought to be same value and same polarity. |

I'm not sure how some of those voltages can exist. In a nutshell, full battery pack voltage at the time the voltage is measured should be divided between S1 to S2 and A1 to A2. In other words, if the pack voltage is 50V and the controller is WOT, then if 30V is dropped across the armature windings, 20V should be dropped across the stator windings. Where exactly are connecting each of the test leads? I need voltage measurements between the studs on the motor, or between the other ends of the cables attached to those studs. Black test lead on A2, red test lead on A1. |

I have to change the file extension from .txt to .csv to load data into my spreadsheet to analyze, so the may have been some data corruption. Please leave the data files in the .csv format and zip the files to post them. You can attach a .zip file to a BGW post. |

Re: Hunting Cart down
OK Will retest tonight.
Tell me where you want the leads? S1 to S2 in F S1 to S2 in R A1 to A2 in F A1 to A2 in R Will from Alltrax also wants me to run another file and check some settings before I run it. Thanks |
