Looking at this makes me laugh at how we did Redshift 1.0. Definitely a compact design for buildability/production. (PS no Alta bits in here :))

The easier way is to replace the module entirely with a known good set of wirebonded cells. Yes you can try to discharge the module to match the p-groups and then rewirebond...but requires time and equipment. In a production setting, replacing known bad with a known good is faster and in some...

PM Sent.

What do you mean by "fixing the wirebonds is not enough". The root cause to the R pack problem was the wirebonds. Now sure there may have been other errors (humidity errors, isolation) The overall goal was to replace as many packs as possible. Now if Alta still existed, there may have been a...

Most of the time the pump needs to be cleaned out from the original coolant usually, the procedure for cycling requires moving the key three times back and forth (on and off). Alta never had one of those pumps fail...and they are pretty dang reliable.... The hoses are attached with heat shrink...

Yeah I have a few still. PM me when you can

It looks like there was some sort of brownout or blackout to the ACM. Could potentially be that the ACM got reset due to insufficient voltage in the 9V. Note: When you are waiting for "target" in mutitool, wait a few seconds post shut down, then turn on the bike. If it does not work, fully...

Looks to be a pretty strong hit. Glad where that hit was the skid frame was there, otherwise it would have been a nice hit on the battery casting. Getting a spare skid frame doesn't hurt, but repairing it would be probably more/same as a spare skid frame

Note: map switch will work on all Alta models. The throttle is only meant for early Alta MX bikes. (roughly to VIN 100)

Pack sold! But as always I do have modules (A and R)

If the motor is toast...I would not recommend saving it as if it is "repaired" and some how delaminates or separates it can cause potentially more damage in the motor housing. Curious to see how its built though....

In most cases the electric motorcycle/dirt bike is similar with traction and weight characteristics of gas bikes. When we took the Altas out on the dirt, the MX33 tires worked out with the best balance of performance and power delivery. On the SM, we used the Rosso II tires and those were...

Uhm that is a clear sign the motor has packed up. Either the bearings are toast or some how the motor windings failed.

Hi All, I have one R pack battery available for sale. Got it last year to refurbish and is fully functional. Currently the cells are all in good shape. PM me for more details on price and shipping (Dont mind the white bits, its Styrofoam)

Its technically both. But the A pack BCU is more suspect to the DCDC dying (which is why this happens)

@JP racing we should get to fixing that top cover

It was a major concern, but over the past few years the parts are pretty repairable. Hardest one is the A pack top cover, but the remaining parts for the R packs along with batteries are replaceable, repairable and usable.

A lot of newer EV bikes use not so "smart" chargers...one nuance of the Alta SM charger was that its really picky with grounds and also voltages...I recall I used my Alta SM to test some electrical outlets at a site in SF I used to work at and it got picky with some bad 110V outlets (which ended...

There is no flasher/relay in the Alta harness, its managed by the ACM. If your going to use LEDs you have to add a resistor inline to slow them down.

No problem, keep me updated on what you do so I can coordinate appropriately. Now on your 9V battery - the ARM processor inside the ACM is able to keep the VIN and mileage data safely with a 9V disconnect (remove and replace). Also all the log data is saved on the SD card in the ACM. So...
