took it for a ride today, it was 16C out
about 10 km's in, EUC World started beeping like crazy
controller temp was at 60C and couldnt hear the fan
let it cool down slowly rode home
opened it up and it has a 32v 120 amp fuse
theres a 12v fan below the controller on the heatsink
the temp sensor is just above the lower right cap
grabbed a hair dryer and the dmm
using the euc world app i could see the temp rise as i blew hot air on it
at 50C i got 12v coming from the controller to the fan
couldnt get the fan to work by wiggly wires or spinning the fan blades
its glued to the shell, no mounting screws
carefully pried it off without breaking it and when it popped off and hung by its wires it started working
kept wiggling the wires but it just keeps working
kept cycling it on off, turns off at 47C on at 50C
dont have any 18 gauge silicon wire in the shop
wound up just using silicone to get it back in place and a piece of fiberglass tape for now
