OK, if it were me, and I had the same things you had, this is what I would do.
1. Get a cheap multi meter, HF runs a coupon for a free one with purchase.
2. Take a wooden board and put 2 nails half way in it, at least 2 inches apart.
3. Cut the small connertor off the power supply, expose about 1 inch of wire and wrap the exposed wire around the nalis.
4. Plug in the power supply and using the multimeter in (DC V) figure out which side is positive. If you get a positive reading + is on the red lead, if the reading is negative switch the leads and the + will be on the red. Mark the board + and -.
5. Using the allagator clips on the charger input wires attach the red one to the + and the black to the -.
Just don't touch both nails at the same time.

Passable method for finding the polarity....

But I would then solder up the correct adapter.

Absolutely, stop gap measure till the right plug comes in...

You can easily find out the polarity without a multimeter. The power supply will be wired 'centre pin positive' so suit the 'old' Accucel charger (the power supply should have a little diagram showing this on it's label if you check).
So just dissect the plug by cutting away the plastic and see which wire connects to the centre pin... and that's your positive wire.

Actually... there are some wired center negative... so its best to check.

Yes but that power supply is sold to suit the old Accucel, which requires a centre pin positive power supply. So unless HK have screwed up extraordinarily badly, it's a centre positive supply. But as I noted it is easy to check because the power supplies have a little diagram on the label.

here is the diagram to look for, the one on the left is centre pin positive:

JPF's suggestion is the better so far - many power adaptors do not fire up unless connected to a load ... basically you stick Meter probes into the plug ... you see silly readings like -1V etc. instead of the 12V expected. Connect up to machine and then check - you see the 12v !!

As JPF ...

I would separate the cable before it enters the round plug ... keeping all intact.

Remove a small part of insulation from one wire ... and with meter check to see if that's connected to outer ring or centre pin of plug. Outer ring is Negative .. Centre pin is Positive.

Mark wires accordingly.

Cut of round plug.

Get an XT60 plug .... + is marked on the side indicating which terminal to solder to.
Solder wires to the XT60 and Bob is your Mum's brother !

Good luck.

I'm starting to agree lol but thank you all for the help! I think I'm going to either try to find another power supply (which isn't working well so far) or just get another charger.

While searching for power supplies, I've also looked at other chargers in case. I like the IMAX AC680, seems like a lot of charger for under $60. It's also 80 watts and comes with seperate power supply, tons of adapters, built in cooling fan etc.

It is highly unlikely that you can find a power supply with xt60 plug already fitted.

Its simple enough to fit your own.

Why spend out so much when a 50c solder job will have you sorted ?

I would return the Accucel, not keep it. I may just solder it to. I was trying to keep from losing money. I feel I may mess it up and be out more money...anyway, no big deal, I'll figure it out.

Soldering is a skill you need to get comfortable with in this hobby... Now is as good a time as any to start.

Really ... this is a mountain out of a mole-hill .....

A good domestic Soldering Iron of 40W or more ... with a WEDGE tip ... standard Rosin Core Solder on a reel ...

This can be sorted in about 10 - 15mins

If you don't like soldering .... then here's a multi lead I just made up for my new iMax Mini :



OK - its on the charge side ... but shows how simple things can be.

The plugs and tails were gash from other gear ... cut of, insulation stripped for a few mm, insert into screw terminal with other leads ... tighten up and bingo.

I have a discharge lead that will charge both Deans, XT60 and Rx ... (not at same time though !)

Alright guys, you talked me into it! lol Sorry this post has been dragged out! My biggest concern isn't really the soldering, it's the wires. This whole center pin stuff has me slightly baffled, ok really baffled. I'm not familiar with power supplys at all. JetPlane and Nigel have spelled it out quite well but let me recap and ask a couple more question:

-using an exacto knife, I'll cut into the power supply right before the end (round plug).
-disect the wires, should be three of them. One will be positive, one will be negative and the other...no idea, center pin?
-Mark wires
-Solder positive wire to positive XT60 terminal, same for the negative and still unsure about 3rd wire.

Also, JetPlane you are correct this is what I saw on the power supply:

FORGET 3RD WIRE .......

This is a signal wire that tells a clever power supply its connected to the right equipment. Dell is notorious for it on their Computers. You are unlikely to find it here ...

Scored an HP 600 ps with power cord for $12.95 shipped
from eBaY.

And never looked back!
