[Solved] Power won't switch on

[lyallp]

Hi,
I decided to have another play of Factorio after quite a break.
Running from within Steam, on 64 bit Linux (Gentoo to be precise)
I can't seem to get my steam power to work.
There is a water pump, boilers (which are primed with coal), a couple of steam engines, power cables from steam engines to power consuming things like research and electric miners.
This is the second attempt restarting with the same result.
See a screenshot of the setup.
What am I doing wrong?

I noticed my boilers may have been back to front, I have tried reversing their direction to no avail!

Reverted to Factorio 0.14.23, practically the same setup (different sizes and graphics, obviously) and my electric setup is working.

Your boilers should be turned 90 degrees and the steamengines should be above the boilers, if you mouse over the boilers you can see where stuff should go.

Thanks, I saw input/output arrows but thought that the boilers had 3 output options.
Trap for old players

Boilers were changed heavily in .15. They take water input on their 2 width side and output steam on 1 of their 3 width sides. 1 boiler can run 2 steam engines.
