One or more of the fuses may be connected directly to the battery lead, and it/they will read the 19 volts - or the same as the battery if you have it connected. I suspect you'll find it at around 12.5 to 13.0 volts DC with a fair amount of AC on it for most of the fuses. With the AC power applied, check the voltage to the fuse input. If my guess is right that it is a linear converter, there should be a transfer relay inside that closes when AC power is applied. Try connecting a battery to it and see if it doesn't simply charge the battery, then drop to a "maintenance" level around 13.2 - 13.6 volts. Without a battery attached, the charger control is pushing the voltage up (20 volts has been reported from one member with a Magnetek linear converter) as there is no current for the current sensing part of the circuit. The 19 volts output is probably the output to the battery. A second possibility is a fan that is getting tired and needs cleaning and/or some oil on the bearings. The metal chassis is a natural "amplifier" for the sound, and sometimes has some other components attached that vibrate in synch. With age, the windings get a little loose from multiple contractions and expansions, and vibrate at 60 Hz. The hum is probably from the transformer. I don't have specific info on the CS4500, but there are some general "concepts" that fit most of the linear converters. It being a 2001 model, I'll guess it's a linear converter with a board for controlling the battery charge voltage (the current model is an electronic switching model). There's a "Contact Us" button on the left side, but it looks like those go to the sales folks. You may get one from the manufacturer - you might try an e-mail: American Direct. I doubted you would get a schematic as I don't recall anyone posting about having one. My computer beat me at chess, but I beat it at kick boxing! Objects in the mirror are closer than they appear. I have posted this for educational purposes only and anyone who actually uses this information is a moron. I would also recommend you not mess with electricity if you are clueless. I would guess that even the parts specifications are close enough to be of help to you.Īll of that being said, it is possible that I am completely off base. With just a small amount of imagination you should be able to use it in your situation. The second link has a schematic of the Magnetek and will be almost identical to what you are using. I give you this page mainly to see the construction of the unit, it's likely very close. The first page talks about converting a Magnetek 6345 to an Intellipower 9145. I know this isn't the same unit, but all the cheap converters are very similar. To Barnacle Bill: I don't know if everyone is as impatient as me.Sorry I came across that way.It's hard to be funny sometimes.Ĭheck out this page and this page. Note: Due to invalid formatting, all formatting has been ignored. The wfco is a much better converter with a 3 stage charger. You can find a wfco to replace it for under a 100 bucks if you look around on the net. Well, don't everyone try to respond at once.is everyone in texas this impatient so early in the am? old lady) is very happy.(won't boil batts.dry, three stage charging ect.)co. I just replaced a conv/charger and was told it was best to replace with best converter wfco 45 than to repair a old unit that is outdated and thats what i did and the TT owner (76 yr. Well, don't everyone try to respond at once. I will probably have to replace it, but it's worth a try. But before I do, is there someone else out there who has a schematic? I found out it's made by American Direct, and I will ask them for a schematic. However, it's what I got, and it worked fine for a while. After reading through the many, many, many posts about converters on RV.NET, I find that Centurion is probably one of the least desirable and least reliable converters of its time. I would like to repair it, but I'm not altogether opposed to replacing it. Last year something happened and now the converter makes a very high pitched hum and the output voltage (bench tested, and TT tested) is 18 to 19 VDC. It came equipped from the factory with a Centurion 300 CS4500 power converter. RV.Net Open Roads Forum: Tech Issues: How to repair a CS4500 Converter Open Roads Forum
