Just one wire left to connect for a test, that would be the ignition wire and I have to consult the generic print to figure out exactly where it goes ( or the little guy that controller is pretty near the same ).
Today was a sweltering hot day full of problems, but I made it all work.
If you look all the way over to the right of that terminal strip you will see a missing screw ( not me ! )
Thats’ number 5 and according to the generic print its the connection point between the magneto and controller.
Next to it are ( obviously ) 3 and 4 these are the make to run terminals.
Closing a switch on 3 and 4 energizes relay CR ( nearest in photo ) and this begins the starting process and the main solenoid picks up and motorizes the generator through the series coil and armature.
A small thermal relay monitors cranking time and a heavy duty Kilxon provides over current protection.
The generator has to fire up the engine before the timing function trips and shuts the CR circuit down. ( not denergized but some of its functions )
But if everything works as intended the engine starts ( !!! )
Then power flow through the start circuit reverses as the engine picks up speed as the main exicter starts to generate DC field power.
CC relay in the centre senses the DC field come to life and heavy loop of wire that originates at the start solenoid has the current reverse it it.
This current when flowing forward inhibited the closing of CC and now that the exciter is generating power it has reversed direction and CC relay picks up.
This disables the CR starting relay functions and brings the safeties in ( if they are wired up like oil over temp ect )
Way over at the end is a steel can, this is an old Autolight 4001 voltage regulator and it with the resistors you see controls battery charging voltage.
Thats all there is in a TI-8 controller
And probably the most simple system I have ever seen to start a generator remotely and still provide all the required protection
If I can find a way to copy the print over for this I will post it.
Its a very good simple system you could adapt to just about any other generator if you have access to some relays and general purpose parts
Here is a photo of the print kind of small and hard to read.
And I made up a nice little remote for this that has some indicator lights to tell you if the DC is on ( DC battery and control power exciter power ) and AC is being generated.
