Hi, Went thru the standard trouble shooting routine from Rad and showed the brake lite was not working. Disconnect the rear brake lite and error gone. Got a new rear brake lite from Rad and still have the code 25 error. Called Rad and they say it's either the cable or controller. Reading the previous posts about controller errors I think it's the controller. Rad wants $135 for a new controller and cable. I opted for the cable first before sinking money into a controller. I might upgrade to a 35A controller down the road. They are sending a new cable at no charge to me.
Nice customer service but I would like a working controller ! I can just leave it alone and not hook up the back brake but I'm thinking the controller is gonna crap out. YMMV.

Yeah, I had this same problem. Rad sent a new rear light , this didn't solve the problem so they sent me a new controller which sorted the problem. All free under warranty and free postage return for faulty items. I have since uprated to a 35 amp controller. Well worth the upgrade. Tony

If the new cable does not sort the problem, I'm going with the 35a controller. It's more expensive but from what I've read it's reliable.. Does rad have a problem with it's controllers? I've noticed some people having problems with them..

I think the brake lights are more prone to breaking than the controllers.

You would think that but from what I'm reading on the forums there are quite a few controller problems. It could just be poor solder joints at the controller/cable connection or bad voltage regulator chips? Who knows.

I have had an error 25 before and it was when I added an extension to my brake light.
What I noticed was the error comes up when the brake light wire is coiled. It seems to be some sort of feedback that the controller does not like. Once I straightened out the wire error code disappeared.

Ok, I'm not feeling the love from RadPower customer service...Error code 25.. Turns out when the rear brake lite is disconnected the error goes away. New break lite did not fix the error RAD POWER said it was either the cable from the controller or the controller. I opted for a new wire from the lite to the controller. RAD sends me the wrong wire and asks for pictures. They are AMAZED that they sent me the wrong wire!! They sent a front cable..Duh... I even sent them pic's..We never Never NEVER discussed the cables from the front of the bike.. ?WTF?
From Rad power:
"Hi Mitch,
The wiring harness we sent runs from the front of the bike to the controller it appears you are looking at the connections from the controller to the rear of the bike."
I mean where is their head at? Then they proceed to try to sell me a controller.. If I can fix the problem with a $20 cable why would I want a new controller? Needless to say I'm a bit dissatisfied with Rad customer service or lack there of...
YMMV

How old is this bike Mitch ?

It's about a 2020... I got it "pre owned" a few months ago so I don't know it's exact vintage.

Mine is also 2020 model but still under warranty so they supplied me a new back light which didn't solve the problem. Then a new controller which did solve the problem. At no cost to me. The 35 amp controller is really worth it performance wise, it's night and day difference if you have to pay for a controller do it.

Already ordered a new 35amp controller. I was gonna do it anyway and this little hiccup kinda sorta pushed me along.. Seems Rad has a controller problem?? Are they "out of control?" ;D

Have you tried undoing all the zip ties on the brake light lead and seeing if you still come up with the error?

Do you think the zip ties are choking off the electrons? ;D I guess if there was a broken wire in the cable unzipping them and moving them around might show the problem.. Or just ohm out the cable with a meter. BTW two days and no word from Rad.. Busy is good.

Yes in a way I do think the zip ties are "choking the electrons". Probably more likely feedback for my field like when you wrap copper wire to make a magnet.
I don't think the insulation is very good around the wiring for the lights. This is kind of happened to me was coiling the wire together and zip tying it to get it out of the way.
Cut the zip ties

As I expected, been there done that, no joy... Cable is back ordered at RAd..
Push comes to shove I'll just ohm it out and see if there is continuity.. Satisfies my OCD of having to check the results of a problem two different ways..

"Choking the electron" is real.
I installed a new Rad rear rack onto my Rad Mini ST and I also observed that tightly coiling the wire around the connector and tightly zip-tying the bundle together contributes to error 25 - that is, "choking the electron." Maybe the connection is tenuous to begin with and any additional strain on the connector bends it just enough to ruin the connection. The problem goes away when you disconnect and reconnect the cable a few times. After a few rides, Error 25 comes back. I've requested a new electric cable (for extending the brake light from the original mounting position to the rear of the rear rack) from Rad and I hope that solves the problem.
This stuff reminds me of a problem a friend had while working on an enclosed trailer (used for supporting Pacific Crest Trail maintenance crews). After installing solar panels and hooking up LED light systems, he was seeing voltage on circuits, when nothing was turned on and the battery was disconnected. It turns out that LED lights can actually generate a tiny current flow when they are exposed to sunlight.
I have also seen LED lights (in my house) which can turn on or off when a ceiling fan is powered up.
Perhaps coiling the wires is making an inductance loop that "reads wrong" in the control system? I wound my extension wires around aluminum tubes and have not had Code 25.
Strange stuff, I guess.
I have also observed this exact problem on my mini 4 and I've read about it with other bikes.
I'm thinking about trying wiring loom - that black plastic loop.
It definitely happens when you coil the wire it doesn't even require a zip tie to duplicate the problem. It is annoying but at least I know how to reset it which normally involves tuning off the battery with the key discharging the controller and then turning the key back on and making sure the wires have not moved with the loose zip ties that supporting it.
