gear sensor

[steveboy25]

Hello after sometime of finding a wiring loom for my engine I have come across the gear sensor its a 6 pin pics below where does this go and do I need it or can I chop the wires off and cap it or is ther a use to it like gear display ECU this is for my go kart no lights or speedos just basic electric starter nothing fance my qustion is do I need it and if I do what do I connect it to cheers in advance

You don't need this in order to get the engine working, they're just there to let you know in what gear you are.

You can leave them alone and the engine will work as good without it.

What type of brand is this engine?

 

[steveboy25]

Its a clone of some sort lad I got it of said its a zongshed 150cc quad engine can I wire it up so I have a gear display of would that be pointless cheers

 

[Nodroz]

I have a Zongshen 150cc too! Cool

You could wire them up so you can get a gear display. I was thinking about 6 lights. For every gear one, including neutral. You'll just have to figure out which cable is for which gear.

Mines are hooked up to some digital display, but apperently my display isn't working anymore. I'll try to do the way with those LEDS. Maybe it'll work.

Nitemeare thes engines carnt find nout on them sack the display thers only 2 down 3 up think ill cap the sensor take the wires out stick a rev counter init and set the revs to a limit and a shifter light hit.man.26@hotmail.co.uk send me pics of your engine wona be nosey and have a look at what u got wired up

Could you please repeat what you said? I didn't really understand it, sorry.

 

[steveboy25]

Its orite don't matter now but thanks for your help

Neither did I

Alex, are you absolutely sure it's not needed? It could be part of the starting system, ie: some sort of cut out sensor to prevent the starter engaging while the engine is in gear

 

[fowler]

id say its definitly needed

there should be a plug in the loom that matches a plug on your engine

 

[Nodroz]

I'm going to hook up my engine without connecting these cables and see if it'll start. Stand by.

 

[fowler]

if its there it would hurt to connect it

some engines run completely differant in diferant gears like limiting the revs in neutral and retarding the timeing in the first few gears to control power
but i dout this engine is that complex

Did you get the starter motor working?

Did you get the starter motor working?

Not yet.

Ok, guys, let's think about this first. These 6 cables are for indicting in which you're in. They just give a small signal. They are in no way connected to anythign else electrical.

You may be right, Fowler, but these systems are not made in the motor itself. It's a digital thing that gives the information to the CDI.

Well, if you just connect the other cables that are coming from the stator, to the CDI and rectifier, I don't see anything that could prevent the engine from starting without those gears sensor cables attached.
Things chance when everything is being controlled electronically. That controller sees in what gear you're in and enable/disable electric starter and could also reduce rpm or power in the first few gears.

That's how I think about this.

Did you manage it get it working without the gear sensor?

 

[Nodroz]

Did you manage it get it working without the gear sensor?

Not yet, I just dissambled the engine and I'm making engine mounts. Once that's done, I'll try it.

 

[steveboy25]

Okay keep us posted please hope it works without the gear sensor

 

[Nodroz]

Works perfectly without the gear sensor. Just tested it out and I saw no difference.

Grate stuff now I can focus on me starter motor my holes on my engine don't line up with the starter motor same size starter to fit the engine did you have this problem nodroz

 

[Nodroz]

Could you show me a picture please? Where did you buy the engine?

 

[steveboy25]

starter motor

Got it given of a friend the engineHers a cupple pics this is the 3rd starter motor I have used but they all seem the same pure confused can you post a pic of your starter motor up so I can see and where did you get it from!
