Heinzmann, Foren 15194 sensor sonnecting mystery

[Hocikto]

Hey guys. I have coincidentaly ripped off cable from Foren 15194 sensor on my foldable trike with Heinzmann motor. Now at the side going from battery there is 6 wires - black, red, blue, white, green and yellow, at the other side going from sensor there is only back, red and blue a bit thicker than those of 6 colours. I wonder how to reconnect it now. Tried just those three same one leaving others without pair to connect unconnected - didnt worked. I cannot find any usefull schema anywhere on net. Thanx a lot for any suggestions

The two wires one three and the other six don't join to each other they must go into a controller and solder to the pcb and you must have ripped them out of it.

The six wire one looks like it is the hall sensors for a sensored hub and has tails of unequal length they either go in to a controller pcb or there is another wire tail with six unequal wires somewhere.
Red and Black are 5v/Gnd.
Green/Blue /Yellow are the three main hall sensors.
White is the speed sensor.

The PAS sensor also goes in to a controller it is a standard looking two part cadence/PAS sensor, the Red is 5v , Black is Gnd and Blue is signal.

Possibly the other wire ends might be within the spiral wrap ?

Instead of small close up thumb nails maybe a slight larger general pic of the area.

So there was that controller unit where both cables met before i lost it..and is it possible to connect it manualy without that unit, or somehow avoid it?

Err no !!!!
Without a controller you can't do anything, the pcb is programmed and uses signals via the wiring.

If you can't get a replacement controller then you will have to buy a new controller kit, cost will be about £100 for a good Lishui or KT brand.

Thank you for your comment!
I saw some thread people are disconnecting sensors so they use direct throttle instead. Do one must have that controller anyway? Also i found at the Heinzmann page that controllers are hidden inside the battery box. Is this controller something additional to that one inside the battery box?

Controllers are either external wired units in an aluminium box or are integrated in to the battery base, even a throttle still has to run via a controller.

Let us see a more general pic of your trike.

Can we see a more general pic of 0048 jpg as that looks like it might be an integrated battery controller ?

Sure i go and take some more pics, but i think it must be integrated controller in the battery box as all the cables go right there and only one is ripped and thats close to the sensor. The other end goes in battery box with all other wirings.. Beside i would have to notice controller falling down when ripping the cables from it i quess, as it happened while remounting the trike after transport. Assume that its not that small unit..or?

See the pictures

I'm pretty sure some how you have ripped both of the wires (3x & 6x) out of the controller or a connector somewhere, you need to unwind the spiral wrap to have a look. The PAS wire has been snapped pretty clean so there must be a tail end for it somewhere which will be connected directly to the controller. Most controllers have wire tails extended 7.5 - 10cm from the base with a connector on the ends, the peripherals like PAS, throttle and motor cable all have the opposite male or female connector and simply plug in. The 6 wires are the sensor wires from the hub motor.

The new pics don't help much, though it certainly looks like that is the controller at the base of the battery.

This is what a complete PAS sensor look like, the othe end with the round connector will be connected still (I think ) so you need to trace where it is. As mentioned unwrap the spiral wrap from the wiring (you can re use the spiral wrap again ).

0050 jpg pic, I expect that the PAS wire is the 2nd from the left, trace it to find where I think the broken end will be.

I know how the PAS sensor looks like, either with rounded or hard shaped connector, im missing that end. The spiral wire i've been through completely, everything leads to the battery bottom. Two wires inside that spiral cover are from hub motor and those are complete. This 6 wired cable goes from disconnected point to the battery bottom. The other end of it has only 3 wires and it goes to the sensor. It means that controller must be inside the battery bracket. Question is, how the wires were connected when on controller side is 6 wired cable and on the other sensor side only 3? Rest of the cable is whole you can se those male/female connectors connected and isolated at the pictures.

And yes second wire from left is the one to the sensor. I have seen your complete message just now, didnt appeared whole before dont know why..Wiring diagram i found somewhere exactly like you wrote but what else is missing when one same ripped cable has 6wires at one end and only 3 at the other and controller is inside battery box? Other cables are untouched

 

[Hocikto]

That clean cut of sensor wire i did myself when i searched for 3 missing wires inside. Otherwise it looked like the other end but only 3 wires instead of 6..
