you.just.need.to.solder.the.shunt.a.little.bit.shorter.

The.ping.packs.are.rated.at.1.to.2.c.

Ping.would.recommend.no.more.than.20.amps.for.that.pack.

You.should.be.able.to.use.it.at.30.amps...but.it.may.not.last.too.long.at.3c..

But.i.would.get.a.watt.meter.to.maske.sure.

hold down "ALT" and then type "255" on the numeric keypad

I'd rather put fire ants in my eyes than go through the whole goldenmotor warranty grist mill process again.

Magzy, try disconnecting your regen brake cable from the controller and see if it makes a difference to your motors performance.

[MonkeyMagic]

Hey Andrew, does that make a difference on yours? jeepers

[GM Canada]

I don't know if it would effect performance but I did have a breif email conversation with Leslie and he believes regen is the culprit for most of the controller failures. It would be interesting to find out if anyone ever had a controller failure with regen disabled.

i know it is unlikely but 'honestly', the pie feels a bit more pokey. I have felt more torque and it seems to speed up/wind quicker   it probably just because I have a sensitive backside

[GM Canada]

Interesting, if it ever stops snowing and the roads clear up I'll have to give that a whirl.

Gary

[Andrew]

sounds like you need a set of these...

You guys have got to stop showing this stuff to me. You know I want everything!

I see they come in both front and rear style. I wonder since I have two motors should I get both rear tires?

I think the controller has just died (for the second time)  

Symptoms:
no power to the motor despite having all 3 led power indicator lights on - and fully charged battery.
When phase wires are connected to the motor, motor is stiff to move.
When I disconnect phase wires, motor moves freely.

This doesn't feel right because I think this happened last time.


can anyone help me diagnose this pls?


this is not good, I've on;y been on the road just over a week and already I'm back to being a pedestrian.

Magzy,

The stiffness in the motor is usually caused by failed (shorted) FETs within the controller, did this happen during use?
If so, was the controller very hot, and did it happen under load or just after heavy breaking etc.?

It would appear that you are faced with two options:

• Follow your own advice and put fire ants in your eyes.
  
• Email Gary and explain your problem, and hope he can organise a replacement controller.

I know which option I would prefer, but you will have to decide for yourself.

Well last time the controller was replaced, it took ony a week to get here. the fire ants reference was for the motor itself.

It happenend while riding at full speed - and just coming up to a long incline.
While riding at full speed, applying power to the motor jsut made it make a shudder sound - and then no power at all.

[GM Canada]

Magzy, you really have to stop wrecking all this stuff! Sorry just kidding. Please send me an email to gaysalo@goldenmotor.ca and we will get you going again.
