I disagree with your stament "Heat Pumps are very sensitive to either under or...


Adding Freon to an air conditioner or refrigeration system takes very specialized equipment and years of experience...it would be impossible and irresponsible of me to try to tell you how to do it through a computer.

Let me explain this further….
In small refrigeration systems such as you have in a refrigerator or a beveage cooler, the amount of freon in the system can often be measured in ounces of weight. Many times, just a few ounces. To get these charged correctly takes tons of experience and very finely tuned equipment. Just removing the hoses can release enough freon to make the difference between the system working or not working. Very sensitive scales are needed to weigh in the freon. To make sure the correct amount of freon is in the system, the system must be evacuated to a complete vacum. You need to have a special pump to do this.


To add to this, most small refrigeration systems are factory charged and sealed. They do not have access ports built into the system. To do anything to these system an access port must be correctly placed in the system for proper evacuation and charging. Then also add the the equation the fact that if you need to add freon to your system, where did the exsisting freon go? Finding and fixing very small leaks also takes sophisticated detection equipment.

The next problem is the many different types of freon that are used today. Some equipment has the type used, very clearly marked, but many do not. Only knowledge and experience can tell what type freon is in the system, and then it can be very difficult sometimes.

Air conditioning systems can be a bit more forgiving, but are getting more and more difficult to analyze and figure out exactly what is going on. The many types of refrigerant and variable speed compressors are making troubleshooting very difficult. Add temperature sensors and variable speed condenser fan motors into the mix and it becomes a nightmare.

Heat Pumps are very sensitive to either under or over charging. The only correct way to charge a heat pump is to evacuate the system and weigh in the correct charge.

Leaks in heat pumps or air conditioners are often very difficult to find, also. But finding a leak and fixing to correctly is the only way to achieve a successful repair of an air conditioning or heat pump unit.

So hopefully now you can see that refrigeration, air conditioning, and heat pump system charging is not something that can easily be done without the proper training and equipment.
Oh, and did I also mention that it is illegal to handle and repair any type of system the contains any type of refrigerant with out a refrigerant handling certification in the United States? Yes, and the although rarely anyone has been charged, it still is the law.

Please call for a certified repair technician to repair any refrigeration system and do not try to do it yourself.

I put in a new battery and now the radio beeps when it is keyed up. I put the old battery back in and it works fine. Both batteries fully charged. Any suggestions?


A beep when keyed up can mean a low battery.
1) It is possible your new battery did not take its initial charge, it can take as many as 3 chargings to 'jump start' a new battery. You might try charging the battery an addition 2 full charge cycles.
2) Try the new battery in another SP50 radio to see if it works, or test with a volt meter, if available.
3) Double check the battery is the correct HNN9018 or equivalent NiCd battery. If you are using an after-market battery, check to see if it is a NiCd. If it is a NiMH battery you will need a fast rate charger to charge it up. (On an SP50 the fast rate charger has a blue button on the tray which needs pressed to put it in fast charge mode)
4) This may sound silly, but check to see you installed the battery the correct way. On a Motorola battery the STOP sign would not be visible when installed correctly.
5) If all these items do not solve the 'new battery' problem, you should return the battery to the place of purchase for an exchange.

Best regards.

Phone dead after overnite charge


It sounds like your phone battery is no longer holding a charge. If the battery is less than a year old, go to a store location for your carrier and see if they will replace. Otherwise you will have to purchase a new battery.

I recently did not pass my auto inspection with the new Interstate Battery I recently purchased for my 2002 Ford Escape. I was told that I need to drive 150 more miles before all aspects of the battery...


NO - sounds like the battery needs to be charged - a new fully charged battery will measure 12.6 volts - if you are not getting this voltage then the battery is not fully charged - driving the vehicle will charge the battery if the charging system is working correctly, but the battery should have been fully charged when you purchased it - batteries will loose charge sitting on a shelf and the best shops keep the batteries they have for sale charged weekly if they don't sell them faster than that - good luck :O)

My 2004 aveo 1.6 L alternator had to be replaced and now the battery light on the dash is still on, and the car runs good and is getting a charge. do i need have my computer reset?


HI, No having your (PCM) computor reset will do nothing to correct this problem. Because the Alternator is charging doesn't mean its charging correctly. This light will come on if there is an over charge situation also. There may also be a short to ground in the charge circuit. I hope this helps good luck.

Display shows battery with red line through the battery


Hi, this is a very common problem, now it could be down to one of two things being at fault, it could mean the charger is no longer charging correctly so the phone is not allowing the charger to charge or it could be that the cells in the battery no longer charge so the phone shuts it down to prevent damage caused by over heating, how ever if you have only just brought the phone and this is the warning your getting then it could mean it is the wrong battery and you need to get correct type.

To test the charger all you need to do is plug your bb into the computer via usb lead then if the battery then charges and your phone comes on then you know the problem is with the charger and not the battery, but if when you plug it into your computer you get the same warning on the screen then this means the battery is faulty or its the wrong battery, in this case all you need to do is buy the correct battery for the phone, blackberry do loads of different batteries that all look the same and all have the same fitting so you need to check on lone the correct battery type or just take your phone into a phone shop and ask them to give you the correct battery, at least taking it to the shop will then let you try the phone to make sure the battery is the correct type.

So the good news is that their is no problem with the phone the problem is with the battery or the charger, the chance are the problem is with the battery so i would try that first by getting a new battery.

How do you install coolant to a refrigerator


It is highly unlikely that you have lost the refrigerant charge in your refrigerator. If you must charge a refrigerator, you will need to braze on the proper fittings, completely evacuate, vacuum, and charge the system with the correct weight charge.

C510 will only MMS not SMS


hi, all you need to do is contact your service provider and ask them for your correct message center number they will give you this for free over the phone but also ask them to send you the correct mms and internet settings to your phone they send you these via txt message and this will update your phone to the correct settings to ensure your being charged correctly as you can be over charged if your using cross network settings.

You may also be able to get the settings from your service providers website as orange are pretty good so you could always have a look their first but if not just ring orange from your phone and ask them to send you the correct settings they dont charge for this and it just updates your phone to the latest settings.

Let me know how you get on or if you need further assistance ok

Dell 1545 plugged in with correct adapter, but not charging.


Battery packs die after a while they are unable to hold charge this sounds like your case, you will need to replace battery pack, if you get two good years out of such you have already done well.
