Doubtful. And if they did, there's likely an exclusive agreement since Alta designed the board and firmware. I recommend that the community works on a replacement.
That temp should not be low enough to affect 50/50 coolant, and there are no moving parts within the coolant jacket around the motor. The battery however, is not effective when its temperature is that low. Warming it up as you did is proper preparation. In the owner's manual, there is...
Have you looked at how that port is configured? It's part of the ACM and it's very important that the connection is waterproof, or goodbye ACM. That's a critical part of the network. If you need the Alta dongle, I can try to help you with that. Send me a PM.
Top photo is the DCCP, same on both packs. Bottom photo definitely shows two stage A pack connector. The low voltage connector on the other side of the bike will be a round Milspec connector.
The letter referred to is a form letter, and if you look at the date (10/25/18) you might realize that it was issued while negotiations were still going on for the possible sale, as they still are now. It states that those who might have a claim against the corporation have until April to file...
I have an EX and the latest version of the firmware. There's not the same challenges with the battery pack with the A pack. There are a few safety and bug fixes that might help you as you continue to ride it. I had some charging issues with the older firmware that went away with the updates and...
That's a pretty early one. EXRs started with 099. Something unusual is going on. Was it a dealer demo? They might have stuck newer badges on it. To change to the R pack you need, battery, harness, ACM, controller, firmware. It's costly.
I don't know the specs, but the deciding factor is inrush current. The ACM detects inrush overcurrent and shuts off the circuit. Google inrush limiting there's a few different methods.
