Im not sure tbh this is wot i bought. http://m.ebay.co.uk/itm/351245268935

Hi people. Im a bit stuck with a project im working on. I have a speed controller im using to control a 24v dc motor, it had a built in potentiometer that i have unsoldered and replaced with wires. I want to attach a thumb or handgrip throttle but i dont think these have potentiometers in them and need a 5v supply is that correct? I cannot supply a voltage to the throttle so trying to find something i can use instead?

yeah I am gojng to strip it down, trying to keep a couple of spares too for any future problems

Temporary wired in a push button switch on handlebars to get through next couple of days. eBay guy is sure throttle will work so ordered one and see how that goes. Thanks everyone for help and advice

Have had a play. And managed to get motor working, I have to turn key on then connect wires else it goes into diagnostic mode! Will keep my hand near ignition goin home ready to shut off! Found a throttle on eBay just waiting reply from seller to see if its compatible. http://item.mobileweb.ebay.co.uk/viewitem?itemId=321105240553&index=3&nav=SEARCH&nid=09476143698 Or when I get home I might dismantle mine and see if I can get a new potentiometer from maplin. Quite handy with a soldering iron!! My other toys thought if share http://m.youtube.com/watch?v=7rQ-rcU0c-k&feature=plcp

Ok cheers no tools at work or multimeter so I think it will be time for eeny meeny miny mo!!

Just broke down on way to work. Pull throttle no power to motor just led's on. Think it is the throttle as when I pull throttle and switch on it won't do diagnostic check. Goin to bridge connector plug on throttle on break later and see if motor kicks in. Their are 3 wires yellow, red and green. Anyone know which I bridge? Thanks

The problem their is that when you switch bike on and its on its stand, the wheel doesn't turn slowly/motor pulsig until after you pulled back throttle and let it go.

Ok so I tried running bike on stand with motor only or pedal assist and it isn't cutting out? In the meantime I noticed when its off the ground in motor only and you pull back throttle and close, when the wheel has slowed down to nearly a stop the motor is almost pulsing and keeping the wheel slowly turning is this normal. http://m.youtube.com/#/watch?feature=youtube_gdata_player&v=-lWso_u2C1Y&desktop_uri=%2Fwatch%3Fv%3D-lWso_u2C1Y%26feature%3Dyoutube_gdata_player

Hi thanks all, it cuts out at any speed. It is getting worse I'm sure so hopefully it will make it a bit easier to diagnose. It's fault is their in pedal assist and motor only. I have just checked connections on battery compartment and all seem tight and ok. It is currently on charge then I am goin to run bike off the ground and see if it still does it?

Be a bit lost without bike, I live 9 miles from work, I work nites too! No buses, couldn't afford taxis. Cannot drive now due to medical reasons, got a young baby so can't rely on wife to ferry me round. All good fun! Can't complain though when the bike goes wrong I owe alot to this bike!

It's an original untampered with bike for sure. The guy I had it off used it about 3 times. It still had the bobbly bits on tyres. The pic I attached before was how I got it like brand new. I have 3 wires coming out speed controller. 1 to motor, 1 to pedal sensor and 1 to throttle. Their are no additional holes in bottom of controller where any other wires can go in. The cables from brake levers on handle bars are deffo just cables no wiring. I also read about some have motion sensors on back wheel? But I can't see that on mine either

Hi appreciating the advice. It certainly played up more on way to work tonite. Then it can be fine for 10mins. I will check all connections tomorrow, if I have a battery terminal issue would the led lights not go off intermittently? I am keen to strip motor and do a regrease and inspection but even though I am competent not sure how to dismantle it.

They just have a cable wrapped in a white protective plastic,I followed the cable and it just goes to brakes, no wires going off to controller. Back to work tonight for 4 nites so the next 80 miles could be fun!

Ok thanks, I wondered throttle possibly? The only thing I have found is that when you pull break levers (either) should the motor cut out? As it doesn't
