It is with great sadness that Clarion Events has decided to postpone the Practical Classics Classic Car & Restoration Show with Discovery. The event team have been continually monitoring the latest public health and government guidelines regarding the evolving COVID-19 situation and acting in accordance with their advice. The safety and wellbeing of our visitors, exhibitors, partners, contractors and staff is the most important factor and therefore the only action for all involved is to postpone.

A few points to be aware of.....................................

Where dynamos are concerned, be wary these days of the words 'reconditioned' 'overhauled' and 'checked over'.

Remember, even the youngest dynamo is 50 years old.

The days of reconditioning, overhauling and checking over units with their original windings are gone. An overhaul or check over can only be done if the unit has been rewound within the last 20 or so years.

Be wary as to what you're actually getting done when you ask for a 6v to 12v conversion. If one size fitted all, Lucas and others would have used that approach back in the day.
That's fact.

We've seen some very expensive 12v 'conversions' that don't perform. Our 12v conversions and 2 brush conversions DO perform because they are done PROPERLY.

I saw one such 12v conversion that cost its owner a serious amount of money. He wasn't happy with it and brought it to us for a proper conversion. All the chap had actually got for his money was a rewound field, a new bearing and some paint.
We properly converted it to 12v for him for less £££'s than he'd originally paid. Another very happy customer 😃

Fresh paint can make something that once looked shabby, look quite nice. Old electrical components included but underneath that paint can lay a multitude of sins.

If considering an alternator conversion, ask yourself why you actually want it? You only need an alternator if you need serious extra power. A well rebuilt dynamo with electronic control is more than capable of powering the usual vehicle accessories.

A 3 brush dynamo properly converted to 2 brush can output more usable amps and is kinder to your battery.

And finally........................

LED bulbs give your charging system a much easier life as well as allowing you to see and be seen. Avoid LED bulbs for sale on a certain auction site as they are very likely to be inferior quality. £3.99 inc. postage and packing isn't going to buy you quality or a guarantee.

We see many different failures here at CDRC Ltd.
Mainly electrical failures as in picture 2.
Oil soaked field coils with rotten insulation is very common but every now and then we get both electrical failure and mechanical failure in the same unit.

This unit lived again and was fully rebuilt to once again grace a lovely 30's Lagonda.

I cannot believe that people are still buying the cheap and nasty Indian made copies of the Lucas RF95 and RB106.
There's actually someone out there now putting Indian made mechanical internals into original Lucas regulator boxes and charging BIG £££ for them (over £200.00!)

Our ADR95 and ADR106 electronic units are available in 6v and 12v, negative and positive earth and are exacting copies of original Lucas units. The attention to detail is shown in these pictures. Hand assembled in England from parts made in England.

You can even fit an original Lucas lid and clip to them for that 'used' look. They're direct replacement, fit and forget units.

No mechanical parts to ever wear out or adjust.
The ADR95 and 106 are fully current limited AND fuse protected. They regulate to 14.2v @ 12v and 7.2v @ 6v.
Ideal charge voltages. They have nickel plated terminals and screws. The ADR106 is available in screw or spade terminal.
Two types of screw are offered 0 Small grub screws for earl applications to 1952 and large grub screw from 1952 onwards.

Available to suit all outputs as original.

Perfect charging and peace of mind........

31/07/2019

1000 miles ago, this CAV three brush dynamo had its armature rewound, commutator skimmed and was fitted with new bearings by a company who shall remain nameless. I couldn't believe my eyes when we opened it up.

My customer decided to send it to us as we've rebuilt dynamos for him before. He said that it'd stopped charging and that there was a clicking noise coming from it.

The clicking noise was the brushes dropping in to the space where two commutator segments had decided they were going to break free from. The aluminium comm end bracket had a piece broken out of it (the break was dirty so wasn't recent). The field coils? Well the picture says it all.

When a customer asks us to carry out a repair on such a unit, if we find a commutator as thin (worn) as this one and field coils like in a state like this, we always advise our customer, along with an explanation as to what we need to do to put it right.

What you see in these pictures isn't the result of 1000 miles of running, it's what happens when a repair or "rebuild" is given to the wrong person. The minimum amount of work has been done here.

Needless to say, it's now going to receive a full and proper rebuild before it once again graces our customers pre war Lagonda.

We see this type of thing only too often. We call it a ‘dress up’. Others call it a ‘refurbishment’ or even a ‘rebuild’.

Take a 80-90 year old dynamo. Take the original armature and field coils and varnish them so they look (remotely) good.
Look at the missing insulation on the fields (pic 😎 and the charred insulation on the armature. It’s being held there by varnish
Skim the commutator to make it look nice.
Attach new pieces of wire to the worn out field tails. Fit a couple of unbranded bearings and a set of new brushes. Assemble and give it a coat of gloss black. It works!!!

Unfortunately, it doesn’t work for long as the insulation and shellac breaks down when it gets warm in use. The result? You’ve paid a sizeable amount of money for something that at the end of the day has been ‘dressed up’. Not good when you’re broken down with a flat battery.

This is a Rotax dynamo from a 1931 Sunbeam.
Pic 1 makes it look nice but don’t be fooled.
Look at the rest of the pics.

A full and total rebuild now begins..............

PLEASE TAKE THE TIME TO READ THE FOLLOWING........

A word of warning regarding alternators that look like dynamos or an alternator built inside your dynamos case.

We're hearing more and more horror stories about metal filings in engine oil, dodgy diodes and ruined wiring when people fit them.These units can produce 45 amps upwards. 50 amps, 65 amps and some even 80 amps. Many units designed for pre war cars don't have a cooling fan or any ventilation slots. Some are bolted to an already hot engine in a hot engine bay. To produce even 45 amps produces a lot of heat and takes some turning. Many units were chain or gear driven from the timing chest. The timing gear will naturally be worn after 80 plus years. The alternator/dynamo will come with a brand new drive gear which won't mesh exactly with your worn timing gears or chain. The extra load on the timing gear is likely to damage the the drive gear and leave you with metal filings in your engine oil. Would you physically pour iron filings into your engine? No. Recipe for disaster. Case hardening is only a few though thick and in an 80 plus year old engine it is likely to be softer than it should be.

Before contemplating spending between £150.00 and £850.00 buying and fitting such a unit, ask yourself one question:

Do I actually need an alternator???

Most people when asked "Why do you want an alternator" give the answer, "Well they're much better than a dynamo" or "Well it'll be the end of my charging problems". In all but a few cases, it will be the start of bigger problems as I've explained above. Most people will have fitted higher wattage headlamp bulbs in an effort to gain more light output. This puts more strain on the ageing dynamo (generally 3 brush). They'll crank the third brush round to give maximum output and even bridge the D & F terminals on the dynamo so that it gives maximum output at all times. 80 plus year old windings are bound to fail.
Some companies (mentioning no names) will dress up an old armature by re-varnishing it. A coat of paint on ageing field coils makes you think they're new again. Shellac was used to insulate the wires in the armature and field windings. Shellac is a natural substance and has a shelf life. 80 plus years of heating up and cooling down takes its toll and the shellac goes brittle and fails. You may have heard the term "shellacitis". This is where shellac goes back to its natural state and no longer insulates the wire it's covering. Outcome? Failure especially where rotational forces apply as with an armature.

You may also of heard the term "thrown its solder".
This is where the armature has become so hot that the solder that fixes each wire into the commutator, melts. Rotational force (centrifugal) then "throws" the solder in the form of a silver ring around the inside of the dynamo. I dare you to touch the tip of a soldering iron when it's switched on! That's as hot as an overloaded armature can get. Serious heat.

The real answer to bad charging in such cases is to have the dynamo fully rebuilt using modern materials. Modern insulation materials don't use shellac. They don't deteriorate, unlike shellac.

Would you fully restore a pre war house but leave the ageing rubber wiring in place? Of course you wouldn't but many people/companies think this is alright with an old car.
It's simple - Refurbishment/re-manufacturing can no longer be done on parts of this age. They are simply past their sell by date - well past it.

We fully rebuild dynamos using modern materials, quality German or Japanese sealed bearings etc. We rewind 99% of the armatures that come in to us. Forget new old stock armatures and fields as the shellac will again be past the sell by date. We can convert a three brush dynamo to an efficient two brush machine and control it with a full protected and fuse electronic regulator for accurate charge control and peace of mind. Current limiting circuitry means the dynamo can never produce more than it safely can.

LED headlamp bulbs mean the demand on the dynamo/charging system is greatly reduced. Less amps to produce equals less heat and less load.

Getting back to alternators that look like dynamos - The weakest points in the system are the wiring loom, ammeter (if fitted) and any switch or connection. The loom will act as a big fuse but unlike a fuse it won't "blow", it'll melt into a sticky mess and generally any ageing switches will suffer damage.
It's quite possible even for things to heat up and catch fire.

Many alternators that look like dynamos are made in the Far East.
Inferior parts are used. Some are made nearer to home.
Wherever they're made/converted, lack of cooling is the problem.
The whole idea may sound good but...........................

See the pictures here. It happened at idle speed.
This is just one case and a mild one at that.
The loom melted. Luckily the owner was working under the bonnet and managed to isolate things before major damaged occurred. The downside? He was working on the carburettor/petrol system at the time.

Say no more...............except, that's why we don't convert dynamos to alternators, nor do we recommend them.
