new GM setup..... having some problems... may have shorted out the controller, as I didnt notice a wire hanging down that got rubbbed by the tire and wore off the insulation... although it did drive after , for a while
tom says...
Hello rob h
The problem of 5 beeps is from the low voltage of battery and maybe the handle brake is broken.
Please check it.
...........also.. when I first set up the bike, the hand brake had to be fiddled with.. it was stopping the motor, on its own..
thanks to any who have advice!

Rob, unfortunately I'm not so good with telepathy, so a bit more information is going to be required.
Which motor, controller and battery do you have?
Which wire rubbed against the tyre? Was it just a single wire or a multi wire cable?
Have you been aware of any sparks or smell of burning etc. which might indicate a short in the wires?
Has it just damaged the insulation, or has it worn through the copper strands too.
Are you able to check the battery voltage? (Assuming the battery gauge is connected, are all the LEDs lighting up correctly?).
Have you tried disconnecting the brake switch wiring from the controller to rule out any possible brake switch problems?
Please give as much information as you can (pictures can be very helpful too), because it's very difficult for us to try and diagnose a problem which we cannot see or experience first hand, like you can. ;)

What is your motor and controller? A magic Pie or mini motor or HBS, magic controller?
Did you short the controller out or the battery?
Which wires, the wires that come from the battery or go to the motor?
5 beeps must mean LVC or interrupted power to the drivers or something that indicates a standby mode like brake switch engaged.

sorry im pretty new at this... so here goes some more info....
all leds light up
no burning smell
disconnected brake and no go
black wire and white wire from throttle worn down to the wire
controller is the external one, that attaches below the rack
i have ordered a new controller.. will try that first, then see...
thanks all!

Maybe the throttle shorted. The black and white wire cross connection means you may need a new throttle.
The black wire is ground and I think in your case the white wire is throttle hall sensor output, so it could mean it has shorted the throttle IC.
-
So now test the volts between the black and white wire when you twist the throttle and tell us what you see.
You should see the volts go from very low voltage almost 0v to about 4v or more.
If you see no change buy a new throttle.
Be sure the white wire is the throttle output wire and black is earth too. Between black wire and battery black terminal should read 0v.
-
Rob, I agree with Leslie and also think it is the hall sensor inside the throttle unit which has been damaged, rather than the controller itself.
You can easily check that the controller is still OK by unplugging the suspect throttle wiring and then using a piece of wire (a reshaped paper clip works well) to directly connect between "T1/5V" and "T2" on the controller.
(http://www.arhservices.co.uk/GoldenMotor/BAC028controller.JPG)
This should make the motor run at full power, so make sure the wheel is off the ground and the power turned on before touching the wire across the two terminals.
The power must be turned on before the wire is used!
And don't forget to let us know how you get on. ;)

Yes to above as well.
Make sure your wheel is safely off the ground before joining T1 5v and T2.
If by chance you end up with two controllers all the better. Test your new one and when it tests good put it in a draw and use it if you ever need it.
Having spare stuff is the secret of making something that can be impossible at times to just manageable.
Its annoying to have to repair anything. Even more annoying waiting for a replacement.
Having a spare motor, throttle, and controller makes life soooo much better.
I cant afford much.
So I'll start with by purchasing three throttles. :P I will never run out too soon.
I am saving for some lithium and a Pie it has a inxternal controller. Taking the price off the smaller items I buy as I save gives me less to have to purchase in the future.
So!
3 weeks from now. Maybe I buy a controller. ???
Comming soon. I've saved for my pie and lithium now. I struggle and do some short cuts, scrounge a little more bucks for another hub.
Get them to throw a HBS48 1000 watt with my Pie and I have plenty to play with.
I still have a working HBS and controller. SO I need some batteries.
I try a 48v 12ah pack and if I like, I work, I save, I scrounge, and in a quarter, I buy a second 12ah pack and sport 24ah of lithium love.
-
appreciate all your advice so far! thanks! still doesnt seem to work..
i will try to order a spare throttle, too.... then I can try both fixes out...
rob
-
So you got a new controller?
-
still waiting for the controller to come in
and... tom also was wondering if the battery could be damaged.. would that be likely in this situation? sure hope not
36v16Ah Lithium......

You said the throttle cable was worn out from friction and no other?
I am guessing your battery is fine.
You should wait for the new throttle before changing your controller. Make sure there are no errors before installing the new controller. Try to get the controller you already have installed working with the new throttle before trying the new controller.
Its the order of expense and operation I am concerned with. You could change the old controller only to find it still doesnt work.
There is a test you can do to test the throttle and controller.
If you purchase a variable 50k resistor pot (below) and put it on your already broke throttle cable. Some citation on the pot value by another member would be appreciated.
(http://media.digikey.com/photos/Bourns%20Photos/3310C-001-SERIES.jpg)
Unplug battery pack from controller.
Discard the broken twist throttle from the circuit, cut it off.
From the broken worn out wire still connected to the controller, Solder the red wire onto resistor pot pin 1. Solder white wire onto pin 2 and the black wire onto resistor pot pin 3. Pin numbers right to left, or left to right, it doesnt matter as long as the red and black are on the outside pins.
This should simulate the throttle fine and the 50k resistance should create enough resistance between the red and black and short the white and black when the resistor is low.
Just for testing this should be good enough.
Turn the pot all the way towards the black wire and switch the controller on holding the brake lever so the motor doesnt turn. Release the brakes switch and if there uis no movement turn the pot towards the red wire, have the brakes ready so you can stop the motor quickly and easily. Or make sure the wheel is off the ground.
Do all soldering with pack unpluged.
Never allow red and black to touch each other.
Test all voltages of between the red and black wire and anything over 5v is the wrong wire. There is a red wire that is used as a battery indicator that has full pack voltage. Beware of this.
If by chance the resistor pot works do not try to use it as your throttle unless you design it properly to spring back to zero throttle. You may have an accident using such a resistor pot as your throttle.
-
Leslie, I haven't tried a 50K pot, but 5K and 10K pots work fine.
The last ones I purchased on eBay were able to plug straight into the Pie's throttle connector, making them ideal for testing purposes.

Sorry for the slow feedback.
This is an awesome idea, there is no way I could of come up with this one because I cut all my plugs off. ::)
Just maybe this might not be suitable because the op has in some form expressed his wires show signs of damage.
Otherwise this test is one for the book.
I think its time to recognise the efforts our seasoned moderator has put into this community.
Hey thanks Bikemad. You really have made a huge difference to these forums and I, and I am sure all the GM community appreciate the awesome enthusiasm you have put into helping all of us better understand the future of electronic transportation.
Cheers. :D

ok... new throttle came in.... wiring harness doesnt match!! any suggestions??

Ummm. yes.

directly connect between "T1/5V" and "T2" on the controller.
Documentation reads that the voltage must stay under 4v or it will go into throttle failure mode, my non GM controller is like this, battery on already or switched on with short, This test will not work for me... There has been some discussion about this. On Allans controller this test works.
On the latest batch of magic controllers, by some chance, possibly the software is made like this.
If you can get a standard 4k resistor or buy one from the electronics store for 20c. Short the terminal T1/5V" and "T2" on the controller with a normal resistor with wheel off the ground.
Please report.
Thank ou.

sorry... you lost me...........
-
if all else fails.. I can cut and splice... just seems like a shame and nuisance when it s a new throttle
also.. I think I will wait till the new controller comes in... maybe that's the problem... before mangling the new throttle wires...................................................
(frustrated in northern ontario............)

Sorry if this is not the throttle you wanted. I have looked back through a few emails where you stated you bought a pie and traded it for your buddies "older Motor". Then you had probems. You purchased a controller. Then you bought a throttle. You sent me this link as to what motor you have
http://www.goldenmotor.ca/shopping/pgm-more_information.php?id=71&=SID#MOREINFO
It leads to an HBS 36v500w motor which has the large plugs. So I sent you what I intended, a throttle for a 36v hbs motor. If your plugs don't match you have a setup from something Im not familiar with. If you can swap the plugs with the old one please do. If not send me an email we will get it right.

ok thanks... sorry for any misunderstanding.... i'm by no means an expert on this stuff... just trying to figure it all out
:)
not even sure I found the right pic.....
-
YAY.... yay it works! it was the controller.. tried the throttle first, and still no go....
thanks everyone so much for all your help....

My Aplogies, I just received some new controllers and they have all mini plugs now. So I guess the controller,throttle etc, you have are all fairly recent items as my previous batch had all large plugs.

thanks! I received the new controller a couple days ago
i will wait till the weekend to work on it, and make sure every connection is super tight
i noticed that the controller box is way too small.. when I try to use it, connections pop open
i will either modify the box, or find something else
if all else fails,... I will contact you later this summer to see what I might be able to use instead, just with the battery I have... I have already spent a lot, and have to save up a bit
:)
