If the green wire is insulated, then another possibility is that the output fuse may simply have opened after many years of operation. The serial number suggests this unit is almost 10 years old! If you find the fuse open, replace it with at least a 20A rated part to minimise the risk of it opening again due to operating in a high ambient at a current too near to its rating. > So do I understand that even if I set this unit up to charge from a 230V > line it still would not be adequate for these batteries? This charger is rated at 1kW nominal regardless of the input voltage, so powering it from 230V will not provide you any increase in output current. > Is there another profile that could be better suited than even #5, or > enough better to be worth sending it off for re-programming? At this time, not really. The issue with not providing the batteries with the required charge current is that Enersys/Odyssey believes they will not end up fully charged. Anecdotal reports on this list in the past suggest that those who have ignored the recommendation have indeed experienced shorter battery life than expected, and I believe, warranty denial. It isn't completely cut and dried, since at least some of these instances have involved parallel strings, which causes additional challenges for charging. I would start with #5 and see how the battery behaves. If there is suspicion that the battery may not be getting quite full, you could try #1. #5 and #1 both target about 110% return, but #1 finishes at 4.5A while #5 finishes at 2A. 4.5A may be a bit higher than these batteries would like, which is why I suggest starting with #5. If the battery appears tolerant of the 4.5A finish rate, then a third option is #2, which has the same charge behaviour as #1 other than targeting about 120% return. 120% return would normally be higher than one would strive for, but given the expectation that these batteries may need additional charge as a result of the lower than recommended charge current, it might be just the ticket. One caution: the charger was previously set to algorithm #11, which is a non-temperature-compensated dV/dt type; all of the algorithms I recommend even trying with the AGMs are temperature-compensated and require that the charger is equipped with a battery temperature sensor. The sensor is standard equipment, and is a black rectangular "blob" that has the black and white wires going in one end and the negative battery connection ring terminal on the other. You should ensure that the sensor is present, just in case it may have been removed previously. > This is not my car, I am just installing the batteries > supplied by the owner along with some other work on it to try to pay him > back for the loan of the car to make body molds to be able to make a body > for my Tropica chassis.

My suggestion is that if you find that the fuse has opened and are comfortable replacing it, then you've done the owner a significant favour. My opinion is that if you find signs of anything other than or in addition to the output fuse has failed, then it is a better use of the owner's money to replace the charger with a larger model than to pay to attempt to have this unit repaired. > I had looked at the Delta-Q site but the support page appeared to indicate > that it is for OEMs only.

The page is intended to discourage end users from contacting our support department directly as a first resort, rather than first contacting the support department of the OEM who provided the equipment to them that included a Delta-Q product. ;^> Cheers, 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)
