I'm trying to fix a solar powered 6volt electric fence charger. I believe the solid state High Voltage transformer has an open winding. It has 6volt input and I'm not sure what the original output was but it needs to be at least 8kv. It has four pins one was connected to the grounded part of the circuit board 2 were connected together on the circuit board and the last one was connected to the terminal to the fence wire. Any ideas on a component I could buy to get this fence charger working again?

6 Volts is a rather Uncommon supply for Electric Fences today.
Possibly a Car Ignition Coil will work? It is Impossible to say, without knowing anything about the circuit.
Probably better to just junk it and build my 12 volt "C-Mos fencer" design.

This fence charger is a Gallagher S17 and they still sell this model mine is only 3 years old. It has a 6 volt rechargeable battery with a solar panel to keep the battery charged. The only reason I don't want to junk it is I like that the solar panel keeps the battery charged. I was thinking about trying a 6 volt coil to see if it would work if I can get one cheap enough.
I may build your charger whether it works or not because I can always use more chargers. Would it be possible to build one of your designs combined with some kind of circuit that would use a solar panel to charge a 12 volt rechargeable battery?

Why not contact that company and see about a replacement transformer for your unit? But are you sure its the Transformer? Yes you can add a "Suitable" Solar Panal to a 12 volt battery to keep it charged and run my Fencer from it. IF the panal just Delivers 1/10 Battery Capacity. (Current Rating) No real Electronics is Required fo that, Just one Diode to prevent the battery from discharging back through the solar panal. Gary

Thanks for the replies Gary.
I haven't tried to contact Gallagher directly but from what I'm told from the dealer is there are no serviceable parts on the units. They just want you to buy a new one.
I'm not 100% sure it is the transformer. I replaced the largest (physical size) capacitor first and that didn't help. What I don't understand is that this is a DC system and this capacitor is a 2.0 uf 250VAC film capacitor. There are 2 transformers the first smaller one I tested 6 volts in and 6 volts out the other is the solid state one that hooks to the fence wire. I took the solid state one off the board and tested for continuity with my meter that gives off a tone when you have continuity. I got a tone across two terminals and that was all.
I have a tractor with a 6 volt coil I thought about pulling off and trying just to see if it would work but it only has 3 terminals +, - and Dist. Is there a way I can connect this when there were 4 terminals before? This is another thing I don't understand why are 2 of the terminals connected to each other on the board?
Are Solar panels specific to voltage ie. 6 volt or 12 volt? Just wandering if I could build your 12 volt charger and use this solar panel?
Sorry about all the questions but I'm a rancher who likes to tinker and I probably know just enough to be dangerous.

Sorry about all the questions but I'm a rancher who likes to tinker and I probably know just enough to be dangerous. Looking up your IP, I believe your in the St Louis, MO. I Wish people would at least state there country. Want to Really Talk, Email me your Phone Number. Free Call for me. Sounds Strange to me that there are Two Transformers. Solar Panals need to be rated at about 5 volts or so, Greater than the Battery voltage. Without Knowing the Intended Battery, I can't comment on the Current you need. Its Impossible to Transform DC in a Transformer. You can Create Output Pulses, by pulsing the input of the transformer with DC, Or convert it the DC to AC with an Oscillator, than Step it up. That is probably why the AC rating on that Capacitor. Without knowing the Circuit Design of your Fencer, Its difficult to really comment on it, or a possible transformer. On a Car Coil, the Start of the Secondary is connected to one side of the Primary. This Might cause Problems in your unit. More that likely, it is Either a Bad Transformer or a BAD "MOSFET". Solid State Transformer? Whatever you think that is? Or do you mean a "Ferrite Core" Transformer?

Gary,
I am in Lyman, Nebraska. I will send you an email.
Sorry about my lack of knowledge on terminology I'm just a rancher. My experience in electronics just stems from playing with electronic sets when I was a kid back in the 1970's. What I'm calling a "solid state transformer" is a transformer encapsulated in epoxy. You can see through the epoxy so I cut away the plastic case to see if there were any other components in the epoxy and there is not. I could not tell you what kind of transformer it is.
I think my best option is just to build a new one.
Thanks again, Dan

Gary,
I will be sending you money for the parts as soon as I can get to town to mail it. But in the mean time I took the 6 volt coil out of my tractor and hooked it to my fencer. It only had three connections so I hooked the - to the ground on the board and the + to one of the 2 connections that were connected on the board the dist I didn't hook to the board because it just goes to the terminal that goes to the fence wire. I'm not sure if this is connected right but I get one whale of a shock out of it. The spark is jumping up and over the plastic piece the dist. wire hooks to and to the - & + terminals.
I have a fence tester that you poke a small rod in the ground and touch the fence with a terminal on the tester and it will read how many kv you have. If i hold the one end on ground and the other on the dist terminal it wont give me a reading but if I pull the terminal back away from the wire about 1/2" I get 12kv. I think the tester will only read up to 12kv since the international standards for the maximum voltage on an electric fence is 10kv.
Do you think I have this wired right with just 3 terminals? Do you think the reason the spark is jumping so far is because I'm getting too high of a voltage? Is there away to add something in the circuit to adjust the output down? I got my finger a little too close to the wire and got a pretty good jolt without even touching anything.
Any help would be appreciated because I would like to get this fencer back in operation before I get the new one built.

Any help would be appreciated because I would like to get this fencer back in operation before I get the new one built. Car Coils Puts out 15Kv to 25Kv No Easy way to cut it back. But I don't know why a srandard of 10KV? It isn't the Voltage that is dangerous, its the Current and Duration of the spark. What connections you have should be OK, but make sure you ground the case of the coil (I Assume its Metal). And DON"T Run it WITHOUT being Connected to the Fence or you will damage the coil.
