| Subject: | Found it at last-Coil feed wires not crimped on new |
alternator coil.
<<Crimps.JPG>> I've been chasing a charging problem on an aircraft in
my hangar for a few years. J430 3300 Jabiru. Some time ago the agent
changed the alternator coils for new ones whilst doing some elimination
fault finding and the problem seemed to be cured for a year or so though
it was never clear what the problem was.
However a few flights recently have shown some intermittent charging and
on the last flight the radio packed up as the voltage was so low. The
battery situation wasn't clear as it had been swapped many times for a
spare so we started with charging the battery fully on the ground. Still
no charge when running and as I began to start with measuring the AC
from the coil I noticed some scorching in the AC lead connectors, see
attached. Examining the scorched one it came off in my hand. I gentle
pull on it's partner and this too also came off. The ends on the wires
were stripped and 'tinned' but it is clear from examining the crimps
they have never been either soldered or crimped to grip on the
conductor.
Suggest you give your AC connections a good pull next time you have the
cowlings off in case yours have the same problem which may manifest
itself at an awkward moment. May also be worth sliding the insulation
back and examining the crimp appearance or chopping them off and putting
better ones on.
Regards, Clive

Thanks, Clive....I've had an intermittent high voltage report (from
my EIS) and by the time I can glance over to see what it was, it
corrects itself. I will look into this.

I just thought of something, Clive....when I first got my engine, Ben
Krotje told me to cut the connectors off from the alternator leads
and crimp on the normal 1/4" wide terminals. I had forgotten about
this (it was 3 years ago), and I was just wondering if you still had
the original, narrow, terminals on your alternator leads when you
noticed the problem?

Yes these were the originals. You have it covered already and I suspect
Ben came across the issue many years ago....
The first Jab engine I got I looked the connectors over and they looked
good so I just used the 1/4 blades in them and heat shrinked over the
lot. They are still on the plane and it's done 1000 hrs with good volts
throughout. It was likely that these badly fitted ones could have lasted
as well. I'm not sure if my Esqual engine has them changed or not, it's
an age thing.....

Clive, great info and photos. Did this manifest itself in engine performance one
way or the other or only in charging the battery ? What time frame did you buy
the 3300? Thanks, Bill of Georgia

Hi Bill. only effect was battery volts dropping thought not
conclusively. Charge light didn't come on for instance.
Plane was built in 2004. New coils (with dodgy crimps) were fitted in
2006 or 7.

Clive,
Are you speaking ignition coils (two of them, either black or dark gray
in color) or the "coils" in the rotating alternator??? A mismatch in
terms here might tend to confuse those of us who speak American English.
Connectors in ignition coils should have no impact on charging.
