My controller was not hot - it blew up on initialization - nothing to do with overheat
The initial blow-up was probably due to dirt or a poor solder joint,
and it happened the first time I switched it on.
This blew one MOSFET, I actually drove the car for about 40Km with the blown MOSFET
The second blow up was due to my not replacing damaged parts
Also I was draining the caps by operating the throttle with the main contactor open every time I shut down
I think this contributed to a failure Paul had in one of his prototypes
