Delco Remy Generator

The generator on my C-85 is dead (according to a local shop). Unfortunately,
our shop used to be helpful in pointing out the problem, but has now
succumbed to liability fears. We don't know if it's the brushes or the
armature. We'll try replacing the brushes first.

Does any one know a good place for ordering replacement parts or a rebuilt
replacement? Any helpful tips or suggestions would be appreciated.

first, verify that the brushes are in good spring contact
w/commutater; that all commutater segments are in place & no burnt
segments. Next, remove belt. disconnect field wire(s) & connect to gen
housing. Apply 6v or 12v (as appropriate for gen) to the output
(armature) lead or connection. If generator motors in same direction
as it normally operates, then it will generate (& you have
successfully restored residual magnetism to armature).

To isolate (& elimanate the voltage reg), reinstall belt, hook up
armature (big lead to regulator) normally but leave field(s) grounded
to generator (and engine and airframe). Fire up & put voltmeter across
battery. As you speed up RPM you should 7-8+ volts (6v sys); 14.5 or
better (12v sys).

If this passes test then we will talk about adjusting regulator after
you reinstall field(s) normally.

good luck & watch out for the prop!!

You might want to put it back on and then take the band off of the back
of it that has the air tube on it.Then being careful,take some fine
emory cloth and with the eng. running,and the cloth wrapped around a
small popsicle stick,you can clean and polish the arm.Sometimes you get
a buildup from the brushes on it.If it works,you will get power at about
1100rpms or so.Jim

A few years back, I posted several stories about getting the generator of
my own C-85 fixed. They're collected at:

Many tractors and dune buggys use similar generators. You might be a
little less candit with the next rebuilder you talk to.

Hi,
I had both Delco-Remy generators overhauled at Aero Tech of
Louisville. Mine were 24 volt, 50 amp units. I also purchased solid
state regulators to replace my old breaker contact style ones.
They've been working great since I did this a year and a half ago.
Their website is www.aerotechlou.com. Even if yours is not listed,
you might contact them. Their work is first rate and they are very
helpful over the phone with troubleshooting. Just a happy customer.

Well, since the generators on the early Continentals were identical except for
the geared end to the Chevy and Buick generators of the early 1940s, and since
I'm sure that C-85 is powering an airboat, I'd take it to a shop that
specializes in automotive generator overhauls.

We've got one here in town (Motor Electric) that does all my "airboat" work.
They also have sources for modern solid state regulators for those old
doorstops.

Brian,

That information will be helpful to me. I had my starters overhauled
a couple years ago by AreoElectric, but they are no longer in business
or at least not doing that any longer. I want to send my generators
out soon. They are also Delco 24 volt / 50A units. I have installed
Zeftronics solid state generator controllers with a built in
paralleling circuit. They are very smooth and work great. What type
of twin are you flying? Mine is a 310G.

Thanks,

Never told him it was for an airplane. Told him it was for our airboat. He
didn't buy it this time ;-). We have gotten some great info from a
particular antique John Deere tractor website. It would seem that many of
the parts on a Luscombe come from tractors. If we could only find a supplier
for our tired oleo springs, life would be fine.

Thanks, Brian. We've heard nothing but good about them.
