Motor started running in reverse

Ok here's the problem I'm having. First let me tell you what I have a Crystalyte 3540 motor, Infineon 12 MOSFETs 30 to 90V controller and using a 72V 13.5AH battery. This bike has about 2000 miles on it with no issues. Yesterday while riding lost power turned it off and back on and it starting running in reverse without touching the throttle. Turned it off and on again and it started running full speed forward again without throttle applied. Now every time I turn it off and on it keeps wanting to switch directions. Any suggestions on what I should be looking for.?

Maybe a new controller.

Make sure the throttle(or the CA, if the throttle is wired thru it)isn't passing a signal voltage when at rest(just dis-connect it).
Those controllers have a "reversing wire" so I guess you could play with that. Hard to imagine(at least for me) what could make the controller go back and forth though.
 
Ok, so I eliminated the throttle powered up and it still runs backwards. (side note didn't have my knee out of the way peddle came around and left a nice gash right below my knee. So now I'm pissed!) so at this point can I assume it's the controller? Or is their something in the hub that might be causing this?
 
What is the status of the reversing wire? Did you try connecting/disconnecting it?
(wire` diagram @ Ebike CA)
 
Didn't try that. I also posted to Illia at Ebikes SF telling him of my problem he is who I bought all my parts from (great guy lots of knowledge) haven't heard back from him yet. I will go look at the wiring diagram and try to reverse but I'm kind of hesitant to do that as the bike has performed flawlessly for 2000 miles.
 
Really depends on how hard I push it Ill get 25 full throttle up to 100 if I help it. I have hit 56 mph on flat ground my setup is on a 29er so a little sluggish at start but top end screams.
 
Yeap
I have the same motor on 29er/48v 11Ah and want to convert it 69er 20s.
 
I live in the Napa Valley road bike teams are quite commen here. I my be an ass but it's so much fun to come up on them make them push to try and keep me behind them blast by them. I have raced vehicles all my life and I believe this is the funest vehicle I have ever driven/ ridden. It all about speed!
 
I'm also thinking about running a front hub to get me out of the hole a little better need to do a little more research though. I don't care much about weight. If you have power just going to stick you to the ground better.
 
Sounds like you have a short on the reverse wire or to the reverse pin if no wire. Running that motor in a big wheel set up for high speed with a little 12fet there's probably all kinds of heat issues happening, and not just confined to the controller.

I won't comment on antagonizing cyclists that way other than to say they're established and organized to get rules/laws in their favor, so that kind of thing can't result in anything good.
 
Sorry I was in no way trying to offend anyone. I have many miles on a rode bike. And I commend anyone that rides on two wheels.
 
Seriously? Approaching a group of slower riders, following them for a while and then passing them is a provocative act? Exactly how are you supposed to share the road without hurting feelings, never pass someone who is wearing Lycra? Apparently ebikes in Napa are restricted by custom to the speed of the slowest peloton irregardless of the speed limit. These high dollar road bike people have some kind of sense of entitlement if that's their attitude. What is it that has given them the expectation of special privileges over other bicyclists? Their money?

I could be wrong, but I don't think there is a section in the CA Vehicle Code that addresses hurt fee-fees and rewards them with special rights over other legal users of the public roadways.

Around me, not dying instantly is considered a horrific act by some of them. Same thing that gives them the sense of entitlement about everything. They tell themselves the rules don't apply to bikes. THEY get to DECIDE. And I've seen the cyclists fight each other. Funny how the mountain bikers are so polite when they have to leave one of the horse trails for a block or so, but the road regulars have so many jerks. No idea if the mountain bikers play well with the horses, but I could see where the horses might have taught them some manners.

It's not just the lycra. Downtown tonight here came two blazing along on the sidewalk yelling at people to "Get out of the way." I think my eyes were doing some blazing also went I turned around, after making several people dive for safety they swerved and went around me. Yeah, it would have gone real bad for that lead bike if he'd tried anything. And they DO try it around here. This was two guys in white shirts and black pants, if it gives you any thoughts on who they might have been.
 
I'm not saying they can't be jerks or aren't already against us ebikers. From the OPs post I got the impression that he was toying with them some before passing. Sure they need to get over any idea that we are racing them, which is the root of their resentment and makes them thick we are cheaters.

As far a sidewalks, they're a foolish place to ride even with no pedestrians whether under pedal or motor power and legal or not (look up accident stats), especially going fast.
 
Can someone explain "toying"? If I'm driving down the road, come up on a slower car and in the course of waiting for a place to pass, the other car speeds up a bit, what does that have to do with me? The other driver is the one with the free will to choose their speed at any and all times, if they choose to resent being passed and speed up in response, as long as they don't speed I'm happy to follow, just as I am happy to pass when they slow down again if they choose to do so. What is different about bicycles? I include ebikes in "bicycles" since CA law considers them to all be bicycles and are all under the same rules. There are different classes, but mostly that applies to bike paths and trails, not the public highways.

I do understand that all road riders are supposedly Athletes in Training as opposed to being Lazy Ebikers, but isn't the law supposed to be applied the same to all who share the road? I wasn't really aware that wearing a gaudy costume and riding a hyper expensive spindly bicycle conferred special rights. My Bad..... :?

Good luck with that. It's your lack of awareness of their godhood that gets you in trouble. Ignorance of the law is NO EXCUSE. One of these days they'll start up an organization. Something like 'Biksis.' THEN you'll be sorry.
 
Update: sent the controller in and it tested fine. Looked over all wiring and it also looks fine. I am now thinking the cycle analyst v3 has a malfunction. The reason for my thinking is as soon as I power it up the hub starts spinning sometimes forward then power off and back on runs in reverse. So the hub is getting power. Has anyone ever seen a v3 go bad?
 
I'm not aware of any wiring to the CA that could cause a motor to spin in reverse.

The only things that cause that are:

-- wrong phase/hall combo, which isn't likely if it was working before,

--connecting the reverse pads or wires on a controller (if it has them),

--a failure in the controller that causes it to forget which way it was supposed to spin the motor.

The second one could potentially happen if the wiring got pinched and caused a short. It may also not show up in a test off the bike, because it would only happen while the wiring is touching the right spot
 
I took the controller off the bike, sent it to ilia at Ebikes SF he tested it and said no issues. That is why I'm thinking it's the CA. When I power up the CA with the hub unplugged throttle signal shows it working. But if I plug in the hub and power up starts turning the hub without touching the throttle. I may be wrong but I'm thinking a pinched wire would not transfer all the way to the hub. As it should get its signal from the controller. So my thought is that the CA is sending a constant signal to the controller when powered up.
