CARRERA VULCAN E 2017 BOTTOM BRACKET

[daverave]

i think the bottom bracket ring as you say is seized...i can see rust on the torque sensor metal bracket the one which holds the sensor in position.

So am I right to think the micro controller is the part on a battery or battery charger that is coded and communicating with each other and the main controller?

Check this out on e bay
MICRO INVERTER ENPHASE IQ8 AC Solar inverter New & Unused
Item number: 365853537893

It’s new I could do a bit cheaper from e bay price say £80.00 they cost minimum of £120.00 .
If it would do you for power in your shed , not sure how worthwhile 1 X 450 W solar would be I was thinking of putting a 36 V led lights in my shed run from salvaged batteries or just for charging batteries or both .

Just do not have time to mess with it at the moment .

A micro inverter is like converts the DC from a single solar panel into AC for your house. LEDs run off DC. If you want to have power in your shed from solar panels, the easiest way is with a power station that you can get from Aliexpress. They range from small enough to work a string of LEDs to large for around £20 to enough to weld with (15kWh) for around £2000.

Thanks I was thinking more along the lines of building a large 36V battery out of that plastic system on e bay from a number of scrap batteries or just using the spare packs I have .

Use the 36 v battery just for light at night does not have to be 36 V could be 12 or 24 depending on which LEDs are used , just thought to use 36 as the battery packs are already 36v.

The Enphase Micro inverter brings down the voltage at the panel to 240V AC then just use a standard battery charger to charge the battery so just have a 240V socket in the shed then all the power tools and battery garden tools could be powered from Solar .

At the moment I do not have the time so the inverter is for sale on e bay .

Hello Baz.....The microcontroller has inputs and outputs...like for say the pulses it sends to the hall effect sensors in the motor and then the pulses are sent back to the micro controller which decides if all the pulses are correct otherwise the controller will send out an error signal to the LCD display...which is only function of many. The inverter im not in need of as ive repaired the one ive got and have another as a spare...going to the bike shop soon to get the bottom bracket ring undone if they can move it !!! david

So on the Carrera STL battery BSM in the photo,s if you could change the Microinverter that allows the battery to charge to one that does not have a code if this can be done could you then just change the controller to a standard one then I think the original charger should still work or change that as well to a standard e bike charger.
If this would work then the battery could be saved and used .
Obviously One would also match the LCD and the PAS to the new controller.

Verses changing the BSM to the Hailong one change the other components as above .
Up grade the battery with input and out put fuses .
If the current on and off PCB can not be used install a different one .

I am not going to do this it’s just out of interest but I am going to look at changing the BMS systems in the later batteries so perfectly good Samsung Battery packs do not need to be scrapped.

Thats what the man at the bike shop said that he uses a long bar to create leverage....but i have not a bar like that...i work in the living room which is not very nice as living in a small flat !!! i really wish i had a house and i would build a proper work shop to fix my bikes.

Lock up garage that you could in time get a solar system for lights and battery power , have a look round or see if the council have any cheap garage s to let

Finally got round to going into this Carrera LCD the one from the latest Crossfires .
Two wires had detached from the PCB.

It’s only for my use to use on my bench testing set up . It’s not in the best condition

Is it ok just to fill it back in with silicone or plastic bumper upol filler ie it will coat the PCB just to seal it back up ?
Or might it over heat .

Less work than trying to cut a new piece of plastic then trying to attach it

There's no real heat in there, so should be OK. I think those LCDs come apart if you heat them up a bit to melt the glue, like you do with most phones these days.

Oh ok thanks I have a new small one that is broke it was stuck on walk assist when I get some time I will try a heated up stanly blade to try prize it apart .

Hello Baz.....I have now fixed the bottom bracket into the latest frame....im a bit fed up as i bought some secondhand clarkes clout brakes and i think they are not suitable for the vul can....the brakes that came with the other frame are the original vulcan e brakes but the brake levers have been cut short and need replacement levers...i was hoping to take the levers of the clout brakes but not compatable...also both sets of brakes are not working correctly and maybe need refilling with hydrulic fluid which is something ive never done and the shop want about £25 to do the job...sometimes i feel i should have just made do with the 22" frame vulcan....instead of keep spending on another bike..

When i was talking before about microprocessors in the controller i got a bit confused...the micro processor does not produce the pulses that go to the motor pcb...the pulses are produced from the motor pcb and then fed to the microprocessor...just thought i would correct my error, im get ting old and not thinking correctly sometimes !!!

I know how that feels
If we could just Identify the components on the Carrera STL battery BMS that is stopping the battery from charging on the correct charger would be helpful even if we have to change the controller ECT .
These BSM’s just unplug and unscrew so not a lot of work getting them off the battery .

I have bought some industrial strength Acetone once it comes I will get them clean and get them to you .

Did you get your BB off ?

 

[daverave]

Hello Baz...In the end i had to take the old frame to the local bike shop and they removed the seized ring...they used a long bar tube as a lever to undo the ring !!! ive just ordered two new brake levers from clarkes direct and much cheaper than ebay !!! it will be good if you can remove the resin from those bms boards which will make fault finding a lot easier !!!

 

[Baz the balloon man]

Yes some times you can go direct if not Suntours kit and get new parts Clark’s like most parts now are made in China Ali Express is ok if you have time to wait for parts .

Topbikekit that San Eagle recommended are good I have found too , I am going to buy the New BSM boards from them next week and some KT parts they are fair prices for small orders too .

Do you still need the BB ?

 

[daverave]

If you come across a suntour BB for the vulcan then i would be interested as a spare part as we have two of these bikes...i have a problem with one of the clarkes brakes...when i pull the brake lever it does not travel far and its like a resistance...ive changed the break pads but still the same and i wonder if it could be sticky pistons...but i wonder if the problem is in the brake lever assembly itself ???? any thoughts on this ????

 

[Baz the balloon man]

Brakes no if they are oil try changing the oil and bleeding them .

If you need Oil brakes I have a good set on the Crossfire that should fit on your Vulcan.
If not I new or nearly new cable original ones

BB yes I have

Battery original I have broken ones welcome to try repair
Just about to call you when I saw this

 

[daverave]

Hello Baz....Since i last wrote i notice when i pull the brake lever the pistons do not move so ive cleaned them with alcohal but it made no difference...do you have a clarks M2 that is original for this vulcan as i think maybe the pistons have a problem...or maybe need mineral oil ??? also im interested in the bottom bracket if you have one the same...any original faulty battery pack you dont want would be useful.

 

[Baz the balloon man]

No I do not think so I think all the brakes are Teko both oil and cable but I will have a look .

I have only ever removed Teko brakes from the Vulcans I have broke are you sure Clarke are original?

I will check the brand on that Crossfire as it’s the same sort of age .

I tried to call yesterday the Acetone has come so I will get these BMS boards cleaned up and look for a bike to buy down your way so make a day to come meet.

 

[daverave]

Hello Baz....I have two sets of brakes...one set the clarkes M2 and the other Clarkes M2 clout...the piston on the M2 hardly moves when i pull the brake lever....so i guess it may need mineral oil or the piston is stuck..on this M2 the pistons cannot be replaced...on the clout they are working but when i pull the brake levers the wheels still move...so i guess maybe they need mineral oil or pad change. Good to hear your acetone has come !!!

 

[Baz the balloon man]

Theses are the brakes on the pre 2019 Crossfire see attached later ones have the same brand so I think you would not be going far away from original if original where in fact Clarks .

The later ones have the same brand I have not seen any oil brakes on the Vulcans I have had pre or post 2019.

Have you checked the original specifications ?

They are in full working order

 

[daverave]

Hello Baz....i know those brakes in your photos as i have them on my Trek bike...the brakes on both the vulcan bikes i have are 100% clarks and are M2 but not clout....on the side of the brakes
there is a large red oil drain screw and ive seen these brakes on most 2017 vulcan e bikes.
