Date: Sat, 28 Jan 2006 9:48:33 +1300

Hi all,

Have had the alternator lamp come on during flights recently. On my 

last flight I had to eventually save battery power and load shed as 

the GPS shut down.

Before delving into the electrical side, of which I am no expert, 

has anyone else had problems with their alternator/regulator? I have 

used the exact wiring diagram Europa supplied for my Classic 

monowheel. Engine has only 50hrs on it. First started when we had 

cold weather. However I did have a problem with the battery +ve 

connection which has been rectified. Any thoughts? Will check all 

connections?

Cheers,

Tim

regards

Rowland

CHECK YOUR REGULATOR WITH AN OHM METER,MINE WENT BAD AT 100 HRS.

I assume it is a complete failure ? I have an intermittent

failure to charge ! I am sure it is a dry solder joint

somewhere inside the regulator which costs 150 and has

components worth 10 in it (max !)



If yours is a permanent failure it is much easier to diagnose.



You need to take the orange connector off the regulator

and add some small capacity wires into the faston

connectors - being careful not to leave any shorts. use

the orange connector with its existing wires as away of

keeping the additional wires in place.



Then connect up your voltmeter and stand back - staring

the engine.



First but the voltmeter in AC volts mode across the GG

terminals (the cables to the engine).



It should read 14 tick over - 30 ish at high revs. If not

- then the problem is the stator



The change to the B+ terminal and to earth. WHen the

engine is running is that at 12.5 volts DC (if so then it

is the regulator, if it is at 14 volts then the problem is

further towards your "alternator" switch.



Keep moving that way until you find where the break is.



Health and Safety. Propellors are dangerous !



if you are not exactly clear about what I am describing -

ask me again direct and I will make a bigger effort  Do

not let any of the temporary wire short to anything !



you will need to charge the battery up to get the engine

to start, and if it continues to not charge then you will

have to keep charging up the battery.



Or come up and discuss it when you next "drop" into town

Sam,

What regulator did you use as a replacement?

Thanks,

Dale

Sorry,



Forgot to attach the URL.....



If you can read German, here's some interesting info from Ducati on the 

regulator.  Also has some schematics and a cross reference for the TP154E 

thryristor (2N6507).

Bill,
	




Interesting find.

Unfortunately, it's not German, but Danish 

Much harder to translate.

The schematic is not quite that of our rotax regulator. But it has some 

similarities.

Bill,

Must be a skandinavian language. German, Dutch, English, French, OK but 

that's all I can read and understand.

The latest Rotax Installation article by Phil Lockwood explains the Rotax  

912 electrical system including the operation of the alternator lamp.  You  can 

find it at the following link:
