Hi, Ive got a Plug-In-Systems PMS5V charger in my Stirling Eccles 1992 caravan that isnt working.
Has anyone got a wiring diagram or schematic for the charger?
Also, no 13.8v output, so does anyone know how to repair? Are there any internal fuses?
Does anyone have a connector diagram?
Anyone know of a replacement??
Im an electronic engineer so I can mend it if I get a wiring diagram!
Thanks
Yes, they do have an internal fuse. In my case the internal fuse blew quite dramatically the instant power was switched on and I sourced a replacement main board from a place I found after a bit of Googling CLICK HERE I'm not sure of the exact model charger I had - it was definitely by Plug-In-Systems and it was in a 1995 Abbey caravan so similar vintage to yours. Anyway, I still have the faulty board. If you are anywhere near me in West Yorkshire you are welcome to call round and have a look.

------------- The optimist sees the glass as half full. The pessimist sees the glass as half empty. To the engineer the glass is twice as big as it needs to be...
The nature of the beast is in the name.. plug in systems, everything plugs in the back so easy to disconnect the unit to work on.
You need a 3.5mm drill to remove rivets from the cover side of the box and the wiring is then plain and simple enough to see. The charger pcb can will be one of two types and generally the faults are simple enough to trace.
There is a 25A in-line blade fuse on output wire of the power source/charger which will blow if battery is reversed by accident perhaps?
First problem with the power source is a blown T3.15amp fuse, this works in conjunction with a thermistor and a varistor to prevent fire and it's common for the varistor to be become permanently short, so check before replacing fuse.
From memory you want to see around 650k ohms across live and neutral
Hi, I have the same problem with my PMS5V, the charger is not working(blows the 3.15 fuse instantly) I have found the red capacitor to the right of the fuse(240v side) has fried itself(cause of my problem maybe, I am trying to find the rating of this capacitor, but not having any luck. Would anyone be able to help please?
There are numbers on the capacitor (2754 and 9551), but can't seem to find a value to match these numbers.
Thank you for your reply.
I have managed to repair the board Thanks, but will keep your number to hand in case I need any further help.
It turned out to be the VDR1. Replaced it when I eventually managed to find the ratings needed, after discovering it had blown its guts out on the side you can't see.. Nice steady 13.8v now.
