Exclamation DeltaQ Quiq Q 48 Volt Charger Model: 913-4810-e3b - Install directly to Batteries

Delta Q QuiQ charger Model 913-4810-e3b.

I removed the male DC side connector and have three wires (pic attached).
Wires: green, black, and white.

After removing the top of the charger and examining the wires. (White is positive and black is negative) .. The green wire? It's near the relay connected to J18 I believe it says on the motherboard.

In reading, "correct me if I'm wrong" - this wire you just leave out. (Green wire)

I have the wires connected the the furthest rear side of a Ranger EV.. White to positive and black to negative.
After plugging in the charger, goes thru the normal start up process and then the bottom warning light flashes in 1-2 second intervals a constant 1 time red flash at the ! Warning .. Based on most of the delta q manuals it's means "battery voltage too high"

Using my volt meter I looked at the voltage for the negative (BLK) and positive (White) wires are connected and its right at 50 Volts (perfect) ..

I'm scratching my head on this one.. Maybe I have the wires connected to the wrong area of each battery bank.
For those not familiar its two 48 volt banks running in parallel.
Should I be using positive on one bank and the black wire to (b-) on controller?

Looks like all of the wires (brown) which probably have to do with interlock are connected to the (b-) on controller.

Backing up for a second ...
The old delta q (model: 922-4800) is still installed onboard (4 bottom lights stay solid but will not start a charging algorithm. They just stay solid, do not flash, just solid and it makes this constant ticking sound. I've taken this original charger apart from head to toe and examined the board for blown capacitors and anything else that could be causing this and even cleaned boards and tried putting fresh solder on any weak spots. Did not help or resolve the issue. But the original charger still has the interlock working and voltage reducer to run dash & lights so I left it installed rather than buying a new $200 voltage reducer and having to require stuff.

So I figured I would then mount another delta Q charger (model:913-4810-e3b) next to it and just use it to charge the batteries up and this will be a viable setup.

At this point I just can't figure out the wiring for the new delta q charger to be used directly to the batteries.

Pics below.... This has been a week process and I feel like I'm 95% there with it.. Just need to get the new charger to work correctly now if I can figure out where my wiring has gone wrong on the three colored wires.

ANYONE WILLING TO HELP - Your time is appreciated. I've been speaking with Lou from a ranger EV forum (he is very knowledgeable of Delta Q chargers) and he nor I really know where to patch the issue.

First, we need to know the algorithm set to in charger. To do this, unhook DC wires & plug in charger. It will flash lights to indicate mode. Some modes require the use of the temp probe, which sends its data through charge port & green wire. If this is the case, you will need to switch to a mode without temp compensation. Did your other charger use a "grey wire" with a little box on the battery end of the wire (temp probe)?

Here is a video I did of the charger being plugged in
https://www.youtube.com/watch?v=cbGEv-SmDms

I tried resetting the algorithms every way possibly and could not successfully get the algorithm to move past the currently selected algorithm. Disconnected positive side of battery and did 3 second connect and disconnect .. Kept going back to same algorithm.

I tried removing both the white wire and black wire from the battery bank and using some tiny wire gator clips to make and break the connection between the connector. Kept staying on same algorithm.

At this point I really am growing a hatred for delta Q chargers

-- THE RESOLUTION --

After talking with DeltaQ support team for hours today figuring out what the issue is and why this charger will not allow me to change the algorithm. Turns out, the algorithm cannot be changed and there is ONLY 1 for this specific charger!
The whole point of a Delta Q is to be able to change the algorithm based on the various types of batteries. Horrible move for Delta Q with this model specifically. Why even have a model with only one 1 algorithm and setup to be used only for RXV EZGO carts?
Apparently, the RXV (2009 & Later) put something inside the controller that interacts between the controller and this Delta Q charger.

Great design and great idea... Ha, not really.

WITH ALL THAT BEING SAID - THIS ONE IS NOW FOR SALE IN THE SALE SECTION!

n conclusion, if buying used have the seller get off his lazy *** and give you the model # to prevent yourself from being in my situation.

Problem resolved by using a 10k resistor on the green wire to kick the charger on. And also removed the stock factory algorithm and replaced with algorithms 71, 72, and 73.

Works beautifully

Does the 10k resistor go to ground and the green wire or to the positive voltage and the green wire?

What did you use to program your DeltaQ?

No, it only goes to the green wire. I used a Delta QuiQ programmer to change the algorithms
