Swift 2S4V Symphony Systems panel help

[Ian_374350797]

Hi,

I have just bought a Swift Corniche which has the 2S4V Symphony Systems control panel on. Problem is no charge to battery. I have checked out the output from the transformer and that is fine. I have tested to the big capacitor and this is where it seems to me there is a problem. One side has 14V the other 0.48V then the wire goes to another rectifier type module which I don't understand! there is some type of component across the capacitor.

Can anyone offer any advice?

Cheers, Ian

The Capacitor is marked with the Negative side, the other side being positive so that's probably ok. Your right about the other component being a Rectifier as well and it's probably this at fault, Take a picture of the connections and take the rectifier along to Maplins, they should be able to match it and identify the unknown component.

The trouble is though, even when working well it's hardly what can be called a battery charger? it's maximum output is 4 amps but at a lowly 12 volts and therefore of little use for charging a battery, however it should get somewhere near....... eventually!!

Thanks Gary for your advice. Would it be better to swap entire system, could you recommend a decent unit?

I actually did this about 7yrs ago to one fitted in a 1985 Ace Rallyman, for some strange reason I now own this van? If anyones interest it's for sale complete with nearly new NR full awning and of course upgraded battery charger!!

The problem with replacing it is what to do with the hole it leaves behind?

What I did was remove the insides and the central divider, leaving just the front controls and wiring.

I then drilled plenty of holes for extra ventilation and installed a 'Plug in Systems'12A,13.8v power supply as used inside their 'all-in-one control centres.

Connections then are straight forward, mains into the old transformer go to the new board via original switch on the front panel and the output from the new board connected to the supply wires to the front panel switches and fuses.

Now everything on the outside remains exactly the same, all the connections on the back are the same and the control panel works just the same. The only thing that is different is the little green LED on the front, it stays green instead of always turning red if you use anything 12v lol
