Dear Jabiru Listers,



My name is Jeff Paris. I built, own and fly a Zentih Zodiac CH601XL powered by a Jabiru 3300 engine and this is my first time on this list and I was hoping for some answers about a problem I believe I'm having with my airplane.



Two weeks ago I was flying home from Canada and had to land in Rochester to setle with US Customs.  As I was making my way into the Class C airspace the tower was having trouble reading my transmissions.  I also noticed that the orange/red warning flag in my turn coordinator was pulsing in approximate unison with my strobe system as it flashed. Once on the ground the tower read me loud and clear, but I had turned off my transponder and GPS to get some wattage back for transmission.



After customs finished with me I was not able to start the plane, dead battery?  I pulled the cowls for good measure and a inspection under the hood and nothing was out of the ordinary in terms of loose connections or damaged wire.  I jumped the plane and headed back to my home airport.  I kept my eye on my Xerion Engine analyzer voltage readout as well as my Dynon readout: They read at the start of the trip about 12.1 volts and decreased to about 11.7 volts.  Normally I'm seeing 14.2 volts at cruise power indicated on each gauge.



This week I pulled the cowls and did another inspection in whih I tested the battery with my multimeter and I was getting a reading of about 11.9 volts.  I then thought maybe my Odyssey PC625 dry cell Battery had a bad cell and was not able to charge itself properly.  Of course I went out and got a replacement battery and re-installed and thought let's see what happens?



Well I went flying with my Father to a builders forum at a nearby airport and I noticed that my volatge readouts seemed to be dwindling again as we made the trip to and fro.  My question is What is wrong here?  Is my alternator already shot after 166 total hours engine/airframe.  So far my engine has been a solid consistent and reliable performer.  Does this have something to do with my volatage regulator?  HELP!!! I can't find anything in my engine manual that clues me in.



Thanks for your time consideration and your expertise.

Jeff, your alternator is not producing, what you are

reading voltage wise is battery voltage.  To charge

your battery the alternator has to produce 14 volts to

overcome the internal resistance of the battery.  If

you are reading less than 14 volts (approx)then there

is something wrong with the alternator or voltage

regulator or wiring.

Sounds like the alternator to me. It should put out 14V, which is what you

normally see. The battery by itself is 12V, so without the alternator you'll

see voltages around 12 that go down and down until they're too low to run

your electrical equipment. Seeing 12V on your engine monitor is a sign that

the battery isn't charging. It will only go downhill from there.

I've had a few problems like that.

I've traced them all to bad crimp joints.

I've now soldered almost all of the high amperage connections

between the alternator and battery and have my fingers crossed.



When I cut open the bad joints I can see that the wire is oxidized.

It makes a high resistance connection that stops the current.



but, it may just be me + my work practices ........

(I did use good quality terminals + crimper.)

Jeff,



Below excerpts from my archives.



Hope it might help.

As a possible short cut to the cause of this problem, the alternator will

not charge unless the regulator is connected to the battery. It would be a

good idea to confirm this connection and the master switch and circuit

breaker in this circuit.



The two white output wires from the alternator should each show more than

12V AC at idle and about 30V AC at 1200rpm.

Subject: [jabiruengines] rectifier/alternator problem



hi, can anybody help with the advice?

My charging system stopped working yesterday in flight.

all the wiring seems OK. I think the fault is coming from th rectifier

as the EIS tachometer (that takes information from one of the two

wires from the alternator) is working.



how can I check?

can I run the engine with the rectifier diconnected and measure the

voltage on two white wires comming from the alternator? how much

should I read?

is there a way of checking the rectifier?



thanks

Martin

Jeff,



As we discussed on the phone the other day you have three possible cuases

to investigate:  alternator, regulator, or wiring.  What did you find?



The most common cause is corrosion in the crimp connections connecting the

yellow wire to the 12 volt system followed by corrosion in other crimp

connections in the system.  I would replace those crimp connectors as a

first step after checking that the alternator is working.



To check alternator disconnect from regulator and test between leads with

a continuity meter.  If continuity exists then the alternator is junk.  If

no continuity then run engine with a multi meter hooked up and set to read

AC voltage.  If 10 to 30 volts (depending on rpm) is present then

alternator is ok.



If alternator is working and all connections are good then the regulator

is probably bad.  This happens once in a while but bad wiring or crimp

connections are the culprit 90% of the time.

Hey Pete,



Thanks for the reply.  I will check out these things in a few days when time permits and let you know the results.



Thanks,

Pete,



Amazing it was the Yellow Wire!  I put a 30 amp fuse in line and it must have gotten some moisture in it and the fuse blew/cooked in the supposed weather proof boot it came with.  The stators and the copper wiring were shiny and when we fired the engine up my readings on the voltmeters went up to 14.3 volts.



Thanks,



Jeff

Jeff,



It seems that most of the complaints about alternators not charging are the

result of the yellow wire or the connectors on that wire.
