Sorry this got long, I ramble when I get interested!
So in the best case only the wire adds too much resistance and I just need one new wire.
Yes best case scenario it's just that wire.. but something had to short out to cause that wire to melt in the first place, so something could be broken. Might have just been the moisture though, if you're lucky! If you replace that one wire but not the broken part it's attached to you could see more sparks though; potentially even damaging another component in the process. I wouldn't replace that wire before checking out the dimmer/heater just to be safe.
don't really know what kind of wires I need and if they sell the same wires also in Europe or if there are differences in units.
100% confident that the type of wire is not special, it's typical stranded copper wire you should be able to pick it up at any hardware store. It's hard to tell from the image but I believe the size is either #14 or #16 AWG. It might be stamped on the wire in small writing. The sizing is backwards, #14 is larger than #16. If you're not sure go with #14 AWG (~2.08 mm2, 28/.03 stranding if that means anything to you?), it can handle more than enough current for the SSV.
I guess you guys might use a different wire sizing though? Honestly as long as it doesn't look to be smaller wire you'll be ok...
The colour of the wire is not important it's just to help keep things separate. Just make sure the wire you get is stranded
copper, isn't visually smaller than the wire in the SSV, and can fit in a crimp connector
like the one currently on the bad wire for easy install. (They're called nylon fully insulated disconnects. The colour on these
does matter, different colours are different sizes). Alternatively you could use a
wire nut or
push connector to join the wires, if you have trouble finding crimp connectors.
Unfortunately now that I look closer it seems the wire coming off of the dimmer is soldered on.. so you'll either have to do some soldering to reattach a new wire to it; or see if part of the wire coming off of the dimmer is still intact enough to splice onto before where it melted.
When I mentioned a meter I meant using a
multimeter to check out the resistance of the individual components.. I think it's probably the only way a person could reliably figure out what still fully works, other than the old trial and error test of course. But just be careful if you decide to get a meter! They're extremely useful tools and it's easy to find affordable ones, there's tons of good tutorials on how to use them.. BUT -
They are not safe to use on LIVE circuits unless you are 100% confident in their operation, seriously they can explode.
You wouldn't need to use it on anything powered/live to check the resistance, so it's not dangerous to use it to check your SSV parts..just obligatory PSA for when you find out how cool meters are and want to start checking everything you own
.
If it were my SSV... I would take everything apart and measure the resistance of the heater and the dimmer (which is pretty much just a
potentiometer I think? Hard to see but I think it's just mounted on a board) to see if their measured resistance values match up with the expected factory values.
If I got a resistance (Ohms) that's way off then I know that component is damaged, no way around it I'd just have to replace it. If the resistance values match up with what they're supposed to then I SHOULD be totally safe to just replace that melted wire and fire it up. Probably would have to contact 7th floor for the right factory resistance values though, not sure they would be visible.
Either way reparing my existing unit will be probably cheaper than to get a new one.\
I think so too! I was going to get an LSV during the 4/20 sales but they wanted over $50 usd for shipping!?
Then there's the import fees.. yikes. The work itself isn't too difficult, other than the soldering can be a little tricky.. But it's already broken right? Not much to lose!
Anyways, hopefully something in all that rambling was clear/useful to you
@Vapordreamer! I'd be happy to provide more assistance in a PM or something if you try to tackle it yourself and have some difficulty. I've also heard 7th floor is pretty good to deal with over the phone so they might be able to provide you some support!
Good luck! Let us know how the repairs go; hopefully you'll be riding the wave again soon!
