Wow Roger, thanks for the great post, even though some of it went over my head! ;)
<One last thing to check: where is the enable signal coming from? The Auburn manual states that the enable signal can be <anything from 12V to pack voltage, which might result in someone thinking that they can use the vehicle 12V system to <provide the enable signal. E.g. use the switched +12V ignition line from the keyswitch and run it through the potbox <enable switch to the controller enable input. This will not work (or not reliably), because the vehicle 12V system ground <should not be connected to the traction pack. The result may be that the controller enables unreliably. I did indeed have it wired from a ignition switch enabled fuse block with a 20a fuse to the red enable wire of the Auburn Scientific controller. This set up never failed once while i was in Santa Cruz.... <The wiring diagram in the Auburn manual shows the enable signal being taken from the controller side of the precharge <resistor, as I suggest, but also shows a diode between this point and the controller side of the main contactor. Does your <installation have this diode fitted? I don't know that the diode is essential, but it will prevent the enable signal from <being held on for some time by the charge stored in the controller bus caps after you try to disable the controller. I do have a diode on the bottom/controller side of contactor, so I removed all power from red enable wire to controller and precharge circuit and waited about ten minutes for precharge circuit to read 0 volts. i then jumpered red enable circuit wire to controller side of contactor, and voila! Motor and controller are now functioning properly. I took car for about a 3 mile trip with no problems.... *(^_^)* I will test more in the morning Thanks, Scott -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/85-VW-Cabriolet-Newbie-please-help-m-m-tp4663524p4663559.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
