So my secondhand radrunner 2 came with the basic power button on the handlebars.
My wife has a redundant Display and power button because of her eggrider V2.0
I tried swapping them over and everything works except the lights.
The front light on the radrunner 2 has a switch on it and the radrunner+ doesn't but that's the only difference I can see, they both have the same plug

Any ideas ?
Do I need a radrunner+ front light ?

They were replacing my controller on my radmini 4 and sent it to the preious owner's address when they were on holiday and it got returned to UPS.
They're not replying to emails that they previously had done

Picked up a radrunner 2 cheap yesterday with problems.
It had had it's battery replaced as the original was stolen and the controller had been butchered to strip the battery connection back to fit an XT60 connector to it.
The seller said his son had ridden the bike in the rain the previous night and blown the controller.
I got the bike home and collected an XT60 male to Rad female adaptor from Big Game Bikes so I could use an old radmini controller I had knocking about.
Plugged it all in this morning and the throttle works but I'm getting no PAS.
I know the controller worked ok on my radmini 4 before (except it had error 25 and I just uplugged the back light to make it work)
The PAS LED is flashing as the crank turns so I'm guessing that's still ok
Any ideas ? I've left the brake lever electrical cables disconnected as ones missing could that be the problem ? 

Just got the 35A controller from BGB but it obviously needs an enclosure round it.
Are the bags any good or should I use the hard plastic enclosure ?
