Please be aware that Odyssey/Hawker/Enersys recommend/require significantly higher initial charge current than can be delivered to a 72V pack this size from a 120V outlet, or by a 1kW charger such as the 72V Delta-Q QuiQ that you presently have. > The charger is showing that it is set for algorithm 11 and that it appears > to also have 1,2,3,4,5,6,7,8,&27 profiles available.

The serial number you state identifies that this charger is several years old, and therefore is both out of warranty and unable to be updated with newer software or algorithms without being returned to Delta-Q. If the fault #6 indication persists when you power cycle the charger (remove AC for at least 30 seconds to ensure the charger has fully reset), then the charger has detected a possible fault with the DC output relay or output fuse. If you refer to the manual the Bruce P. linked to, you will find Figure 2 on page 3 that shows the output relay and output fuse (F1), and how they connect to the external wiring. The most common cause of a fault #6 is that the recommended external fuse (F2 on the diagram) has not been provided by the user, and at some point (usually during installation or removal of the charger), the green interlock wire from the charger was allowed to short to the vehicle chassis or elsewhere while the battery pack is connected to the red (B+) wire. This event can result in the internal DC fuse F1 opening, which will result in the fault #6 and an inoperative charger. The Delta-Q website lists contact info for our distributors, so you can identify if there is one near you, and the same page provides the contact info for our customer support team, who can advise you on the repairability of your unit as well as where it would need to be sent for service: <http://www.delta-q.com/contact#list:international-battery> Given that this charger is out of warranty, the most practical option may be to have a qualified technician replace the DC output fuse for you locally. Before opening the charger, you can check the condition of the fuse by testing for continuity between the red and green wires with the charger disconnected from AC and from the battery. If there is no continuity, then the output fuse is probably open. If there is continuity, then there is likely an issue with the DC output relay. The fuse is a DC-rated leaded ceramic-bodied unit and is soldered to the PC board in the corner where the DC cable enters the charger. Hope this helps, Roger. _______________________________________________ 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)
