 Monday, September 30, 2013, 15:19, Anders Mjos, , , , , , , Problems/Solutions, New purging valves installed on Heat Shield water circuit
|
The Heat Shield circuit can now be separately purged for water. Use valves on heat shield circuit to purge the lines for target exchanges from now on.
All paddle wheels have been rotated to allow trapped air to escape the system more easily. |

Monday, August 26, 2013, 14:07: The turbo could be restarted, but it does not sound happy (Dimo was consulted earlier today). The pump is drawing around
4 A. The current draw is fluctuating between 3.5 and 4.2 A at the same time as backing pressure is spiking from 0.015 to 0.045 T
Monday, August 26, 2013, 15:32:: The turbo failed again. Dimo had a quick look. It will have to be replaced. See e-fault: 6953 |
