Need help identifying a brushless controller.

Hiya, I am brand new to electric bikes.
I recently bought an old non runner off ebay.
The bike is a Currie Meerkat Trailz (womans)
It turned out to be a 24v bike with a 48v charger.
The seller knew nothing.

I replaced 2 rather deformed 12v batteries showing 9v and 10v and got a 24v charger.
Connecting a fully charged battery, the power indicator on the bike lit the second from empty of 4 leds.
The bike ran for 200 yards happily, then a few cracks and stopped.
The empty led, 1 of 4 was lit.
I am assuming the controller is at fault and I am running into a problem replacing it.

The bike looks just like the TRAILZ ST LADIES here...
IZIP Currie Electric Bikes
There is an on/off switch on the battery pack and no switch on the twist throttle.
The label on the controller has on it...

Currie Technologies.
DC Brushless motor controller.
Input voltage 24v.
Control voltage 1-4v
Output current 25A
Blueprint no. 140L
Make date 2008-02-26
S/N 0802B00070

It has 5 Wire connectors out to...
1) Battery (2 wire)
2) Motor (2 wire)
3) Brakes (2 wire)
4 & 5) Throttle with 4 led power indicator. Two cables, one 3 pin & the other 2 pin.

I am ok with a soldering iron.
Any help would be gratefully appreciated.

I have a novel idea; how about calling the manufacturer?

Thank you. While I don't have a problem phoning them, I do have an enormous problem hearing on the phone.
I have a problem face to face with my hearing and tend not to talk very much.
Sadly it is not really an option for me.

Ask the mods to move this to E bikes, might have some interest there.

Yes, email would be good.
Does anyone have an address for support please?
One that will not reject me for being outside of America.

Yes I did.
It gave me lots of information, beginning with...

We have found that offering tech service over the phone is more effective, and we usually have resolutions within a short phone call.


CUSTOMER SERVICE

+ 1 (800) 377 - 4532
Monday - Friday: 8am – 12pm and 1pm – 4pm PST

Technical Support

Technical support gives me this list that I can choose from...


I was able to find that the closest dealer to Liverpool England was New York Mills, New York.
Although it is not clear about dealer for what.
Another way in searching the telephone number, I get....

<li class="col-md-6"> Email
Full email address info
Reveal Full Address



Revealing the full address gives me....
Whitepages Premium can only be accessed by users located inside the United States

Along the way I was given various email address's for sales.
I spent well over an hour going round in various circles.
Possibly if I spend more time searching, I will find an address that is good.
I did consider just asking you guys to try and save time.

Thank you. Possibly you can answer a question for me.
All the stuff I read on brushless motors indicate they use more than two wires.
What am I missing?

That's odd. With one click I found several plain text and clickable email addresses.

I bet a nicely worded message would get a reply. Something like: "Thanks for offering tech support via phone. Unfortunately I am unable to use that service easily. Can you help me with . . . "

I am sure it would.
Would you please be good enough to give me one of the tech support email address's and I will do exactly that.

I've never had one apart but I would guess that it has brushes. The only way I can think of to have a brushless 2 wire motor would be to use ac voltage and these motors aren't known for having much torque.

I went on the forum you recommended and a big discrepancy is on the "Brushless controller".
They too think it should have brushes.
It has been suggested that it may be a language problem with the Chinese.

Another request to move to e-bike forum. The people that might know her answer are over there and usually dont poke around in this forum.

The endless sphere forums could also be helpful. There are a LOT of people who mix and match pieces to make their bikes go.

Good luck in your repairs.

I don't know how you can have a 48v charger on a 24v battery. That wouldn't work. I assume that is what was given to you, and the 48v charger was never used?!? (i.e. not directly relevant to this question)

Buying used electric motorized stuff off of ebay seems like a fools errand. Nothing personal - a friend got a free electric razor scooter and wanted me to help him. I'm thinking there is no way it is worth the time to try to diagnose and repair, but that is a different story...

Personally, I just disconnect everything from the contorller except the battery and motor, then short the battery wires (giving full power) to see if everything works, and take it from there.


All the motors I have seen are 3 phase (3 wires from motor connected to the controller).

That should be a rather glowing experience. lol

I am retired and working out how to make it work has been a real pleasure.
You are correct about the motor.
The problem was traced to a 24v Chinese charger that used the wrong colour output wires.
Fortunately plugging it in to the battery tripped something in the charger and no damage was done.

I must say a special thank you to AnkleWork. Your help was just awesome.
