Hi, I am looking for a circuit diagram or some decent technical information on the Hercules 20 Charger as fitted to the Jurgens X-Cape Off road caravans. Can anyone assist.
Many Thanks - Alan Exton

Alan

Ask admin my mail address, I have the name of a guy in Pta. North that could help.

I found the info.

Die persoon wat ek van weet om die Chargemasters te herstel is ongelukkig in Pretoria Noord. Maar ek dink dit gaan steeds goedkoper wees om dit vir hom te stuur en terug te koerier as 'n nuwe een.

Sy besonderhede is Leon le grange 0827709813 E-pos leonlg9@gmail.com

Hi All,
I have solved my problem in the best way that I can. I opted to open the Hercules 20 and disconnect the PC Board with the charger. It was working, but the float voltage was far too high and would do damage to the battery which is not a cheap item. I use the 105AHr battery.
I bought a Benton BX-2 charger which is an intelligent charger with the necessary algorithms programmed. It has a maximum output of 7 amps at 12 volts nominal capable of charging from 14-230AHr batteries.
All the wiring remains unchanged and now the float voltage is ± 13.6 Volts which cannot damage the battery, yet keep it fully charged. I leave the caravan permanently on charge now.
Thanks for all assistance received.

That is the one. It is a great charger at an affordable price that will not damage the battery. Thanks

Can the Hercules 10 or 20 charger voltage be adjusted? Mine is too low, 13.2V. Idealy, it should be 13.7V-13.8V for float.

I keep my caravan 95AH battery permanently on charge with a CTEK MXS 5.0. (13.89V).

Groete,
Paul

Paul, maak net seker jy meet nie 13.2 terwyl daar stroom vloei nie? Meet eers na 12 ure op charge, want n tadige charger neem maar n ruk voor hy by float uitkom, maar float is nie 13.8 nie, nader aan 13.5 tot 13.6 is ok...

Hi Brommer. Ek charge hom met my CTEK. Na hy deur all sy ciclusse gegaan het, gaan hy in mainenance mode (Float) en ek meet dan 13.87V. Ek sit dan die CTEK aff en die Hercules aan. Dan drop die spanning oor n' uur of wat tot 13.28V.

Die battery is n' Atlas XDC27MF (90AH Deep Cycle). Volgens die specifikaasie is float tussen 13.2V~13.7V. So 13.28V is dus seker binne perke.

Groete,
Paul

Hi,

I am trying to obtain the specifications and wiring diagram for a Hercules 20.
The Hercules 20 is in my Xcape by Jurgens ( They are totally incompetent).

When travelling I am charging off the Alternator via a Ctek 250 S.
When stationary I supplement with 2 x 100 Watt solar panels, this is very important when off-road.e comes when I must charge from AC and need to know more about Hercules 20 DC Charging.

Battery's are 2 x 100 a/h at 12 volt Deep Cycle.

Is there help out there ?

Hi Alan,

If Pretoria North is too far out of the way I know the person that repairs all the chargers for Comet, Kennis and all the other agents. Let me know if you still need someone to repair your charger to charge at the correct voltage.

His name is Johan Fouche from the East Rand. May be someone will have his details.

I can get hold of him if needs be.

Regards.

Based on information on another web site the Hercules 20 is not a clever charger but very old style. Using a CTEK or cheaper Benton would be much better. If it includes an inverter as is said one would perhaps not want to replace it all together but just add another charger if one disconneted the pc board as Alan indicated he did.

Assistance required please!

As with all things all worked fine untill......
My 12 volt Caravan fridge /freezer suddenly only works when powered from the battery with the power switched off to the charger (Hercules 20). The moment the power is switched on the unit switches off/ stops working. Any ideas what could the problem be. The battery is approximately 2 years old.

Any assistance will be appreciated.

Regards Johan

Johan ek het jou reeds geantwoord op die ander forum so paar minute gelede. Daar is 'n manier op die kort termyn om te help maar ek glo jou DB/laaier oorlaai en jou yskas sny uit op oor spanning. Geen fout aan die yskas kant.

Thanks for all assistance received.

Please help me with this.  I tried to disconnect the 2 charging wires from the battery and add the smart charger.  It then only gives me lights with the mains power on...  Am I supposed to run all the wires from the white plug on the Hercules 20 to the battery?  There are 8 of which 2 are the charger.  

 

Very confused because there are 2 thick wires connected to the battery which I don't know what they are for.  posiibly for the Brad Harrison in the front but I don't know.

Thanks

Switch off all mains power and test the battery voltage with a digital voltage tester. While keeping the tester on the battery, switch on a light and note if the voltage drops considerably or not. If so, then the battery is either flat of does not hold charge. 

Secondly, plug the caravan into the vehicle with the Brad Harrison plug and let the car idle. Switch on the fridge. If it works, it looks like your battery has packed up.

Hi Clive,

You are still getting power from the power supply inside the Hercules to the lights. The only change if I understand correctly is that the Hercules is no longer charging the battery but the smart charger is doing the charging. This is if you disconnected the 2 thick wires on the DC plug.

The 4-6 thinner wires on the plug where you have the 2 thick wires will also have to be connected to the battery. This way you are bound to loose the fuses protecting the pump, fridge and other circuits that are running on 12V.

As Allan indicated you might have cooked your battery due to the high voltage to the battery.

I need to say the following, and this is my personal opinion. I am in no way trying to take on Jurgens or Hercules.  

Intelligent Chargers are exactly what is said and meant i.e. "intelligent" Intelligence can be interpreted by different persons to mean different things. By this I believe that because the charger or its wrapping says "Intelligent" it does not imply that tis is true at all.

So in my opinion the C-Tek or Benton brands are truly intelligent chargers which is what a modern lead acid battery requires. The following is true:

In my Ex-Cape I converted the charging circuit to the Benton 7Amp charger more than 5 years ago and the battery in the caravan has not been changed. It remains in float at 13.6 Volts permanently year in and year out maintaining a fully charged battery without any Hydration. I fitted the Ewik movers and this old battery has sufficient capacity and power to move the caravan as and when required. As you should know, the movers draw considerable power and would be a true test of battery / charger performance. I will personally never use a Hercules charger again. Once a battery has been hydrated it will need replacing shortly. The cost today for a 105 AHr battery is greater than a Benton charger. Do the maths and take a decision. "If you want a different result, you need to change something"

Alan you are right. Unfortunately we live a life where the bigger the better does play a major part. A smart charger can refer to a smart box or the actual functionality. We don't always have to buy the best. Fit for what we try to achive.

The charger a number of members mentioned also in the topic DEEP CYCLE BATTERY is the intelligent charger I do provide at a tenth the cost of a CTEK/Benton. May I say this R200 charger is intelligent in the sense that it charges until the battery is full and then goes into trickle at 13.6V what is needed to charge. It also uses the pulse desulphation option that you will find in the very expensive chargers. Never is it the same as the 5 or 7 stage smart chargers. Not all of us need a computorised charger just to charge a battery.

We all decide what is fit for puppose. I also have some batteries that are over 5 years old and used with this charger for 2 years and we have recovered over 10 batteries of which one was discarded and under a tree for a whole year. That battery still has over 30% capacity left and in regular use.

On this forum we had a quick survey and those members that keep their 220V on in the caravan using the normal Apollo/Hercules are getting very good life out of the battery and therefore I would never knock the standard charger/power supply fitted in the Jurgens CI vans.

Just an observation I had recently. We all suffer with batteries going flat in a modern car if not used due to alarms/trackers/radio memory etc. My 1400 LDV stood for 7 weeks and no charging of the battery and it started very easy. So we pay a price for all the nice to have items.

In the same breath some people still get along with a basic Nokia that can go for 3 days without charging vs a modern phone that cannot even go a full day if used a lot. Again the device that is fit for purpose.
