hmm. 6 windmills, between 1 and 5 eu per tick depending on wind and on height.
from y = 149 to y = 66 = minimum 83 wires required, energy loss would be 2 eu per packet so your output will be between 0 and 3 eu/tick depending on wind and height.
base is currently wired correctly in latest screenshot, so no worries there. Problem is now you're getting between 0 and 18 total eu/tick, of which the engine is eating a minimum of 1/3.
batboxes every 40 down the power tower would allow for between 6 and 30 eu/tick and should allow you to constantly run the electrical engine. problem is then the electrical engine will overfill the pulverizer and then explode, so you still have to turn it off no matter how you look at it.
without gates, I think your only choice is to use a block update switch monitoring the pulverizer, then have it turn on a T flip flop when the machine starts running, then when it stops running the toggle will hit again and turn off the engine.
Would highly suggest using some of those diamonds you seem to have in abundance to create an assembly table, 3 lasers, and a small (maybe 2x2x3 low pressure (12LP)) boiler to power them. That should get you 24 MJ per tick running 6 commercial steam engines (you're on mindcrack, the industrial engine steel cost is silly). At that point you'd be able to create all sorts of gates for all of your buildcraft automation and not worry about such things ever again. Unfortunately, this setup would render your electric engine all but obsolete (you could turn it on to boost base output to 26 MJ tick).
For renewable MJ, you could invest in blulectric windmills (kinetic generators) and solar panels, and hook them up to a blulectric engine. The windmill doesn't need to be nearly as high, and 1 vertical wind turbine will output on average 2 or so MJ/tick, around as much as a basic electric engine (0 on a completely calm day, 9 during a storm)
tl;dr The root of the problem isn't the lack of automation on the forestry electric engine, the root is the lack of a buildcraft power grid and trying to use electric engines as a substitute. The best conversion factor you can get from EU to MJ is around 2.5 eu -> 1 MJ. The best conversion factor from MJ to EU is 4 MJ to 15 EU. (almost 1 to 4) using the magma cycle and the thermal generator from gregtech. Yes you can create a loop that generates around 14000 eu for only netherrack (almost as free as dirt at the rate this thing runs). Yes this is a cycle of somewhat expensive machines who have to do nothing but create this 14,000 EU or else they stop being stable and become useless. The point is that power conversion is hella inefficient and that electrical engines should be used as a last resort when you want to use a lot of buildcraft and Thermal expansion machines...
gotta stop making the tl;dr's so damned long...
