I just didn't want to to solder the 3 sensors re-attach wires close up case on motor and it don't run. But then its best to just test sensors before I close case I just thought that pcb looked a bit damaged, as I did notice a small minuet piece of copper fell onto floor. but way too small to...

No hurry Nealh when you get time. I have now today received the 3 sensors. also have cleaned out the old ones, and new ones fit ok but not as yet fitted them, as need some advice 1st. as you can see by that far left one. I lost a clear thin tube on 1 of the legs from old ones. but I cut a...

It’s ok mate it’s 14mm axle size. I also do have a digital micrometer but as usual forgot about it

It’s ok bud I’ve used a small grinder on them. Got 2 out well the middle one wasn’t even glued in so that was easy. So using that one as a template for others. And the right one is out now. And tried template one and it fits ok. Will use small bit of loctite to fit new ones. I did have a...

Well no way do they have a number on them, as I would say they been there from new, and numbers rubbed off. the middle one was so easy to lift up but god knows how I am going to remove the end 2. as i just tried far right one and its even lifting up the metal of magnets. well if it is magnet...

its so hard to remove them, some of the legs have even broke off, and lost the tubes for some. but its hard DE soldering them too I have not received new ones yet. will they be same as I have

Yes it seems I removed the test probes too quick, as numbers was still going up, so I thought best to wait until they slowed down Why is there 9 mosfets, do that mean 3 for each phase wire then, and how do you tell which are + and - Im just curious nice to learn stuff Also I have ordered 3...

Well it seems I have made a mistake with checking the mosfets, as now I have removed controller from moped and retested the phase wires its seems its all ok so it seems the cable just fried 2 hall sensors. btw will those ones I ordered same as you said fit into those slots on motor ok and do...

Ok I have now opened the controller, and it seems I was wrong its not 6 mosfets, its 9 it seems 3 for each phase colour. I have looked at 1 and it has on it. so what do I order. the green wire is C then CS48N78 45195 33S

Ok so what mosfet do I get or will I have to open controller 1st to check. as I believe there are 6 in all 2 of each - and +

I maybe able to solder in the 3 hall sensors by just leaving that white stuff there, as it seems very hard to remove and dont want to crack that board.

No you getting me wrong, I just said when you quoted about disconnect the battery, was just letting you know I never have battery connected anyway.

Im a bit lost as you say disconnect the controller from the battery, But I have not had battery connected at all for these tests, as you said no power. Ive just been testing wires not even connected to battery. But I just did touch thick red and thick black wires on controller together, but no...

then to touch the controller Black v- & Red v+ together to drain the the voltage. This will give a brief spark yes I have had this happen before made me jump as thought i had blown something ok will do that and get back to you

No what you thought was fried is just black liquid installation tape What is that white stuff in circles. as it seems like some strong paste

So do you think the green mosfet is bad and needs replacing, as I didnt think I would need to remove controller and open it. I cant read the hall sensors identifier numbers as nothing on them, probably, rubbed off when i cleaned the motor. But I have ordered 3 from where you said, just hope...

Hi Nealh firstly I am so grateful for all your help, its most appreciated, I honestly thought after 3 months fixing moped. I was all done. and like I said took it less than 1/4 mile not even that, and bugger me, cable twisted, but that's my fault for not having the proper washers on axle etc...

I seem to now be getting proper readings on the mosfet tests as I have now set meter to 200 ohm mode. I will test again and get back to you. Tomorrow

ok I will do this later, but just feel this has been going on a good 3 months, But as long as you dont mind helping I do appreciate it lots. are mosfets easy then to replace I cant seem to find which wire is the ground one. I have a cut out switch with a green/yellow wire which goes to the...

I do apologies for all this but Im nearly getting to the stage of calling a scrap dealer, as I honestly thought after all this time, it was ok. I go for 1st dam test drive after 3 months of fixing it. go just less than 1/4 of a mile only for cable to twist and break. Im afraid Nealh you will...
