I got the controller back today and we shall see later this summer how the car runs. I want to wait for the EE to check everything over...
Anyway, the controller looks something like a power supply or a transistor amp in that it is in an Aluminum box with cooling fins on the top. It is bolted to a plate and between the bottom of the controller and the plate I found a white paste that I guessed was Lithium grease. I could not find any tubes of the stuff around the cage today in order to refresh the stuff that was left on the plate from when I took the controller off...

So, I did what any good member of the Stijn thread would do and pulled out my nipeloob nipple lubrication paste and used that instead. My motto is always be prepared!   |
Hi Max,
That white paste is most probably a thermally conductive paste otherwise known as heatsink compound.
Thermal grease - Wikipedia, the free encyclopedia
Lithium grease is probably not a good substitute
