I dont care if you removed it, or it fell out or if a magic fairy made it dissapear. It MUST EXIST to work!!!

And its also very obvious that it cannot work unless linked. I was saying this right my first post. And yes I know what you said. We all do!!! But that could not be true. Add a bit of your silicon heat proof wire in a short loop. Outside or inside it makes not a blind bit of difference. And it will no longer be RIP. As I said from my first post!!!



do you see it where it was on mines - those last 3 photos - thats how it arrived - show me where you see the wire - i dont see it -

Your photos dont help as you are not showing the inside where the "springs" go into the connector. Along with those there would also have been a bit of wire joining the two ends of the "springs" together. It would be U shaped, so that each hole in the white connector had a spring and a bit of wire in it. Your bit of wire has been lost since you took those pictures, and first used it. And I have been saying so for 50 posts.

no you havent - you been saying that i am missing a wire cable that joins the white box - the picture shows no such cable or wire - on the inside where i cant see - must have been something there connecting the two coils closing the loop -

and i said that also - somewhere - i never said it could work with an open loop - all i said is - it arrived as i posted - and i dont see any wires - and it worked - you should have known better - and realized it at the start - that if there are no wires looped around in the pictures and it worked this way before

means there was another closed loop connecting the coils - - you could have just said that from the start - and makes sense - instead you keep saying how it cant work with an open loop etc, etc, - YES your right there - it cant - but if it worked - it means it was closed before - just what keep it closed - what ever it was a little U clip like you said - either its lost or loose etc, then making open - and not work

but from the outside - looking at it - all angles front back upside down - i dont see this wire cable - i dont see it there now - and i never see it when i got it - not seeing it - dosnt mean something is not there to keep it closed - two different things

No you have driven me to drink.

The problem is SUPER SIMPLE. You have LOST one way or another the link wire shown in BLUE below. Its not a "clip"... You cant see it unless you turn it over. Then its obvious.

Maybe you loosened the screws or something and it fell out. I have been saying this since post 1 now 63 posts away...

Image2.gif


I knew that one must exist because its impossible to work any other way!!! LONG before I got a carer to look at mine in the garage. I couldnt remember what mine looked like. But ANY bit of wire will work externally. But a bit of silicone wire is best if you fit it internally as its hotter in there. Or bare wire, as thats whats in mine.

i get it - and thats possiable - or the rear screws which you cant see - thats where the coils are connected too - something there could have closed the loop - and must have been lost when i checked last time -

there was nothing ever there that i could have seen with the naked eye - nothing looped over on the outside - if something was there inside - i didnt see it when it was new and dont see it now -

later i will add my wire cable loop outside - and most likely will work then - tonight i try it - after i have a drink - you need a beer now beer


its very simple if you look at my last photos i posted - 3 pics - front rear underneath - nothing visible to my eye - all i did was connect my two cables and worked - the other end with the white box - was never touched - 4 screws - the rear two hold the coils - the front two had nothing there - i can add wire there but nothing that i could have seen with my naked eye

thats all i was saying - you know me by now - SO it only means that something else was making it a closed loop that i never seen before what it was - thats all - not a big deal - now if i try it later and it still dosnt work - what would that mean ?

Also the reason your fan is useless is because they fitted it expecting it to blow through those tiny holes. I used a hole saw in my cordless drill, and made a 40mm hole under each fan. So its very effective. Stay cool enough to hold or touch.

It WILL work!!!

No. If you connect the other end together where the wires go in then you have a total short circuit! And your latest pics do not show the underneath The link is a big bit of wire. You couldnt possibly miss it.

wait now - i didnt see it - trust me - the pics i posted is how i received it and used it till now

what are you talking about blowing it up now -

the end where its labeled 24V - i have my own cables there with the XT90

the other end - thats where i would add a wire looped together - ?


NOT the same end where i have my own 24V cable - is that correct - cant be any other way - thats the end where its an open loop now - if it works

the fans are weak small - i have my own external little fan - steel blades - strong - i use it all the time

You were saying that the link might have been at the end marked 24V. And I said no!

Link the opposite end with no wires... Then its fixed.

And yes the fan is weak. But if you bore a couple of 40mm holes its plenty! No need for external fan.

i dont think i said the link was on the end where its labeled 24V - the other end was the whole topic - where you see nothing there - thats the end where i loop the wire - not touching the other end with my cables already there -

both ends arrived with nothing - just loose fan wire - and one end labeled pos and neg 24V -

I would like to thank both of you for giving me a reason to wake up this morning.
I'm almost sad to see this thing get fixed but I will light up a cigar to celebrate, anyway.
Expresso- send me slice of pizza, dammit!

this is how mines arrived - nothing on the other end - that i can or any one can see - - the coils themselves are whats keeping it closed - on the inside screws that you can really see either


i see hopefully it works later

At the full 800 watts, it'd be about 33A so slightly lower than a dump load device. But you could run 2 or 3 of them in parallel and have up to 99A dumping power! :ugeek:

33A is fine - dont need or want to drain it that fast

actually 33A is most likely what our chairs do most times even less really - sometimes alot more but very short

so 33 A would be a good way to see how it acts under load and helps if you have 200ah to discharge


why would it have two switches on the side for the compact 24V model ?

what would be the benefit to get a 12V 24V model instead ?

what about this one - since its here in the states - the reviews say the wires will melt and its not good -

this one looks good with switch also built in

Well as long as you use some 10AWG silicone cable and place it on something metal with plenty of space around it, it'd work. But I noticed a lot of those get a low rating, probably because they're using the wrong size wire! :fencing

Guess what - it works - i did add a cable loop - BUT - i dont think that was the issue to begin with

the dumb load has a XT90 female end -

the battery pack has a Female end also - so cant connect direct

i have a cable with a fuse inline made also - i also have one of those monitor things that show how much is discharging with a screen etc,

that one has Male ends on both ends - dont ask how i ended up this way

so - i believe now - that the monitor thing - was connected backwards - the battery end on the dump load and load end on the battery

i just noticed its labeled which end is which - one side is the load end - i must have had them opposite ends - thats why it didnt work

nothing to do with the wire loop at all - :lol: always an adventure here - ok at least i know now - i may still buy the other

now i need a drink - some music - will discharge the pack for a few hours - and recharge it tomorrow - give a few cycles to even out the balancing - then discharge and let sit till i get new chair - new pack holding up well with this discharge load - about 40A discharge i believe it is - cheers

This is a 12V/24V unit. It depends on how user connects it, in series or in parallel , just like the two lead bricks in our chair.

If what you have said is true , that the U-wire was never there, then you must have connected it as 12V , or you have just thought it was working but it wasn't at all.

the one side is labeled 24 v - plus and minus and thats how i connected it - i put two wires there - and it worked

the watt meter shows about 1000 watts - would that means its 12V or 24V ?

there is no way you can not known if its working - you know when its working - it gets very very hot - coils turn red

heats up the house - also i monitor it on the pl8 - i can see it working -

i dont have a good explanation of what happened - its possible the watt meter was connected the wrong way - would that make it not work ?
