Thank-you Roger, I had hoped you would respond, you are one of the treasures
on this list.. The green wire is insulated now and has been since I
recieved the car, but I have no idea what may have happened before the car
was delivered to me. I will check the continuity as you suggest and I have
experience in this area so I will look inside if needed. 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? Is there another profile that could be
better suited than even #5, or enough better to be worth sending it off for
re-programming? 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. I want to get it in the best condition I can for
the kindness he has shown me before I send it back.
I had looked at the Delta-Q site but the support page appeared to indicate
that it is for OEMs only. If the check of the fuse and relay don't turn up
anything, I'll try submitting a service request through that page.
respectfully,
John

I have been asked to change the batteries in a Tropica from 12 ea 6V
floodies to 6 ea 12V Odyssey 31-PC2150s. It has a Delta-Q Quiq7212
charger
model 910-7200 and serial DQCP720316000162.
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.
Of the profiles in your charger, #5 is likely to provide the best
performance with this battery.
It also is showing six flashes on the red error light
when I let it try to charge. I of course don't have a manual but the
info
I can glean off the web claims that this is an "internal error" and all
that can be done is to cycle the power or send it in for repair.
So is the error info correct and where would the repair depot be for
northern california? I presume that if it does go in for repair then the
correct charge profile could be set at that time.
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.
