As most owners and potential buyers always refer to the infamous green dots on the motors as having hardened splines (my own belief as well for quite some time). I thought I'd provide some clarity on this as things aren't quite as they seem.
First, Fisker was never completely certain on the definition of the green dots. Let's break down the green dot itself. There are two completely different green paint marks. A large green circle painted with spray paint using a stencil in a broken "O" about 2 inches around is the latest and most current traction motor with a part # index ending in 003. This part # is etched in the motor by the connector.
The paint dot in question here is the small half inch to 1 inch paint or chalk hand drawn circle. Typically found up against the RDM mating surface at 3 o'clock and 9 o'clock positions.
It was my belief up until today that thsee both meant hardened splines. My reasoning was than every traction motor I removed with worn or sheared splines up to this point had no green markings at all.
However I've disproven this theory today as I received a car in from NY with sheared splines. Car won't move, rear TM just spinning freely and singing with no resistance. Both motors with green dots as described above. VIN # in the mid 700s. It's apparent after a lengthy discussion with Fisker tech that the green dot may just be an indication of the improved case welds in production, so they are learning. Seems to be a logical explanation as I have had case weld leaks and also never with green dots or circles.
My reason for this lengthy post is because I have looked at many cars and had many people buying refer to these green dots as hard spline motors when they may, in fact, not be. My apologies if this has misled but we are all learning these things as we go.
The one thing we do know is that a motor part # with an index ending with 003 is for sure hard splined. This # is found etched in the electrical box near the connector with a serial # as well.
Hope this provides some clarity.
