At long last!

 

You will be pleased to know that the Schicke GR6 voltage regulator has been approved.

 

The Mod details are in the Rotax standard mods section on the LAA web site Number, SM12970

 

Note that the circuit diagram differs slightly from the diagram supplied by Schicke.  The LAA circuit should be used.

Ian,



Thanks for the heads-up.  Just found the listing on the LAA website this evening.  That's a tough site on which to navigate or find anything.  

I installed the Schicke GR6 this morning.  Since I hadn't located the Mod till this evening, I used the Schicke supplied circuit diagram of course.

What is the reasoning behind the changes made by the LAA?  

I had also installed a B&C under/over voltage warning circuit so that makes the LED in the Schicke circuit redundant.  Do you know if it is necessary for the function of the regulator?  I would think not.

I haven't had an opportunity to run the engine to check it out yet.  Hopefully tomorrow morning.

In the Schicke provided diagram the fuse (0.5amp) is in the line to pin 4, which is the voltage sense pin.  Our (LAA) circuit puts the fuse in the line to “Gen Led” only providing the protection intended.  In the Schicke setup if the fuse goes the regulator does not “see” the output voltage so it increases it.  We have had a report that this fried the battery in one installation.  The sense line should never be disconnected.

 

You are right there is no reason you need the LED anyway.

Ian, Bob and all,



Sorry for feeling compelled to jump in, especially since I'm not aware 

of your LAA electrical requirements.

We installed a Schicke regulator in our project from the start some 7 or 

8 years ago, after performing some in-depth electrical and thermal 

experiments.



In my opinion, it is crucial to provide some over voltage protection, 

and our circuit includes a crowbar overvoltage module which disconnects 

the alternator and regulator from the ship's bus in case of voltage 

excursion.

The whole system has been working flawlessly to date.



FWIW,

Kindest regards,

Ian & Giles,



Thanks very much to both of you for the explanation, information and advice.



I will go back and check my wiring to ensure there is no fuse in the sense wire circuit.  And I will add a crowbar module before the aircraft flies again.
