BL36 - Sparks - On & Off Switch - I'm New to the Game....

.


I'm new to the game - Thus, ignoramus & uniformed.
Thanks to all that lend help.

RE: BL36 - Stock out of the box with 12ah SLA's.

If anyone has the time, I have just a couple of questions drawing from your long experience:

Even when the controller is in the "Off" position, I get a fairly good sized spark when connecting the battery to the controller.
How normal? Some normal? Remember, the controller is "Off".

Also, while the battery is connected, when either the controller is in the "On" or "Off" position, the whole unit remains "powered up" and is capable of running.
(RED LIGHT ALWAYS ON - GREEN LIGHT OSCILLATES)
Normal?
Switch is just a "dummy" switch?
Controller should be replaced?

I couldn't answer the question about your controller for the moment, but i'm having a meeting with some people from the industry today, whom are very knowledgeable and have dealt with Wilderness Electric quite a bit. I'll ask.

Sparks:
Wilderness Energy claims that there is no spark when connecting your battery to the BL-36, unlike the BD-36. From my experience however, it still happens - its normal for many electric bike kits, as its just the controller taking an initial draw of power into its capacitors that causes the spark.

It can be normal for a spark to occur, my Crystalyte units will both produce a small spark upon being connected. However, I will also inquire about this for you.

Please note that this is a pretty loud "crack" and not a "small" spark.
It's a noticeable arc.

I understand that it could be the caps charging - But it does seem that they "discharge" quite quickly - i.e., when pulled just for a second or two and then reconnected, I will get the loud "crack" and the arc.

yes, any help will obviously be appreciated.

Not a big deal as that everything else is functional - I guess?
It goes maybe 14 mph, as opposed the advertised 20+.
And, I have not had a chance to check the range either.

I might say the concern was a short or an electrical drain; even if when not in use and the switch would off.

Not certain what the switch might be used for?
It does not turn the circuit off whatsoever.

Any help is a BIG thanks....

Well, according to the information provided to me today, the sparking in *small* quantities as I normally experience is normal even for Wilderness Energy's new kits despite what their website says, so a small spark is normal.

The level of sparking you describe is not normal however, nor is your controller remaining active when the switch is off. The switch on these controllers does work, I ran a motor on a test stand today with the same controller pictured in your post. Apparently the green light does oscillate on these controllers normally, but all of your other descriptions indicate that the controller is faulty. Your system should also perform at the expected 20mph, but I suspect that your controller is at fault here as well.

Thank you very much for your diligence. It is appreciated.


The "spark - arc" has mellowed to just what appears to be a normal draw of current - very minimal, now.
I guess that the caps just had to be thoroughly cycled during an operation and thoroughly charged a few times to retain their capacitance voltage.

Yeah, about the On & Off switch, any other feedback will be of use from BL36 owners.
Not that worried, as all other function is well.
I'll just have to insert an "inline" on & off from RatShack (just kidding - never go there...Orvac's or similar)

Regards to speed:
I am not a Fatty, but at 6'1" & #215, I was surprised that I did acheieve the 20MPH.
I was only at 3/4 throttle in the begining, not realizing that there is a "throttle lock" at full throttle.
I had simply not "thumbed" or twisted the throttle far enough for it to lock at full.


All in all, a good unit for the dough.
Did not have all the faith in the beginning, but will now build another unit.

Again, thanks to all who contribute to this thread and all the boards.
Great source and great help.

Now, if they could just get the LiFePo batteries at under 25 cents per Ah x V !

When you turn it off, all the lights should go off. When you turn it on the red light will come on and the green light will oscillate
