Motroino MOTOR HELP PLZ

[tkxxx]

Hello to all. I'm new to this site and herd it was the place to get more knowledgeable on e-bike and all that go with it.

so my problem is with a motorino XPH scooter. i live in ontario Canada and for our electric scooters we have
a small screw on bike gear to allow the bike to be potentially pedaled manually. well this gear due to the nature of the bike cna unwind it self .
when it does it moves down the thread and as it does it cuts the wiring from the back tier motor.

now i have fixed the small wire problems with sodding new connections but my problem lies in the big wire for power. i can not find a way to connect them
so they work efficiently . i have tried these yellow electrician caps you screw 2 loss wires together inside the cap.

so that is my problem i cannot find i way to connect there heaver wire together to complete the circuit . im looking for some advice and
guidance on to what might be a good fix

the photo is of the wire i am trying to fix. i have them twisted together atm

Bigger soldering iron is the best way, if you want a permanent connection.

80W should work. Weller makes a good one; I use it for giant wires and battery terminals, etc.

I'm sure it can be found cheaper.

+1 for solder, and shrink tube.

But if you have never soldered before, it can take some practice and thats a thick wire. Try it on some small wires first.
If you're new to it, about 2/3 down the page are some instructions on soldering a splice. Its easy after some practice.

Another alternative, which is meant to be temporary but I've used to make permanate splices before, Posi-locks. Not cheap, but they work well. http://www.posi-lock.com/

And get rid of the gear!

Hey DS
Those posi-lock connectors, according to their site are not just temp connectors. The waterproof posi-tite ones, ummm got me thinking.
Less resistance than crimp connectors, due less interfaceRs between, between:

Wire : crimp : connector face : connector face : crimp : wire

With these posi-xxx connectors it is just
Wire : Wire

And they do them in up to 10 gauge

Supposedly multi use.

I am thinking for battery and phase wire use to reduce voltage losses from battery to hub

I live on Posi-locs. Really useful (and expensive) but can be reused over and over. Great product!

Do you use them on battery main cables and phase wires ?
What current can they handle..do they get hot at say 100 volt 120 amp battery or 210 phase.

[docnjoj]

Um.........Neil. I'm too old to be in the 100 volt club. I have used them at 60 volts with no problem. As usual it is the amp draw which makes stuff hot, and I have never experienced heating even at 1000 watts. The Andersons do heat at that wattage, sometimes. The posi-locs have a screw type connector that really squishes the wires together even 8 and 10 ga. I hope this helps.

I suspect that there will be very little heating as there is just the one junction, but asking never hurts

Thanks

Unless they changed them, they have 2 junctions. I've been using them for maybe 20 years now, but I haven't bought any new in 5 years at leasty. I still am using some of the originals I bought. they last, and are reusable. There is a center shunt, with 2 cone shaped ends inside the main barrel. the screw caps press the wire ends down onto the cone, making contact.

The reason i said temporary was I've had corosion on that junction on my Jeep, and they failed. That was after 7 years of mudding, rock crawling, driving through rivers with the hood submerged, and parking on the beach with salt water washing against the skid plates. But a true soldered splice wouldn't have failed.


I've used the yellow ones (I forget their guage ratting at the moment) on 120V AC at 15 amp on several occasions.

[NeilP]

OK, yes, I should have noticed the picture, I see that now.

but still , a bit better than a crimped connector on the phase wires, with three junctions

[tkxxx]

do u think throwing the wires in a small silicon cap , and filling it with solder would work?

[NeilP]

Why do that ?
Why not just cut the old twisted wire back, strip some more insulation back, 15 to 20mm each end, twist together straight, solder and wrap with insulation. Better if you have heatshrink sleeving, slipped over before soldering, but if not tape will do. Trying to fill a silicon cap with molten solder is just a bizarre idea
