To supplement Ivan's excellent lesson here, I want to add some important details. Even if you are using flux core solder, add a little dab of additional paste flux everywhere the soldering iron tip is going to touch. It serves several purposes, even when desoldering. It acts as a heat transfer fluid so the heat stored in the iron can dump quickly to the joint without heat soaking and overheating the surrounding area. It allows extra fluid to float the impurities out of the way and breaks the surface tension of the solder so it lays down and wets the joint quickly and cleanly. All these serve to allow you to get in and out more quickly and avoid cooking the surrounding circuit, the component itself, or lifting a circuit trace.

They also make low temp solder. I think it's Bismuth. You can add that to the existing joint. When you're ready, you heat all the joints and the solder will stay liquid long enough for you to pull the part out. However, I would have tried wick first here to remove the bulk.
@calholli

That braided solder wick is better. The vacuum is really only for certain size joints where the pin can go into the hole-- such as desoldering a resistor wire, and would help you cut time if you had to do hundreds of them. It's really kind of a gimmick otherwise IMO. Solder wick is the way to go, especially on these larger lugs with weird shapes.

Nice circuit analysis! I would have had to redraw that schematic. Typically a control winding breaks near the solder joint, sometimes repairable with fine tools. I enjoy how you get to the root cause and make bench restorations with available components. One minor caution: the replacement relay's control winding impedance should be considered to insure the drive transistor is not overloaded, or you could take that fancy thermal camera to check the transistor's temp. when operating (if it's under 50C body temp. it's probably safe).

Love it 👍. Never underestimate the difficulty removing through-hole components. I've fixed a LOT of damaged PCB's due to techs fighting PTH devices that didn't desolder easily. LOW MELT SOLDER is your friend in many situations. The solder sucker is good, but not perfect. And when using the sucker, hold the trigger for a second or two after solder disappears so the molten solder makes it all the way to the glass waste chamber. If you stop sucking early all the time, the barrel will clog quicker. If your kit doesn't have the wire to clear the barrel, buy the one to match your nozzle ASAP.

Nice fix! One thing more I would have done would be to test/replace that blue component - an electrolytic capacitor - due to its age. Without a schematic of the relay module, it could be a noise filter on the power line or it might be part of a timing circuit. Either way, its a $2 part and equivalents are easily found and might save a callback. I doubt if it was the reason for the relay failure, but those components don't age well and the designers felt one was needed to support the module's function.

I have several sizes and you will need to clean it and the nozzle regularly. The Hako soldering iron is not so good. Your iron is probably much better. I eventually bought a Weller D60 which I have used for years. Your better one looks like a really good choice and I might get one. That relay could have been repaired. I have rewound a few things but I do have a rewinding machine and wire.

A very extensive analysis there, using schematic diagrams. In the days when CRT televisions were abundant, I used a manual vacuum pump combined with an ordinary soldering iron to remove horizontal output tranformers (most with the EHT supply to the picture tube anode). My approach would be similar, with the knowledge that the resistance of a relay coil is (nominally) about 200 ohms, and would use the 'Rx1' or 'Rx10' scale on the 'ohms' range (of a multimeter) to test. What I like in your work is that you have diagnosed a fault to component level, replaced it with a 'generic' one, likely surpassing the reliability of the original...

Really love this channel. Creative and good solutions. But if you want the hakko to work better next time, i have two suggestions. First, give the heating element much more time to warm up when using it from a cold start. Give it ten minutes. Also to let the old solder flow better, add new solder first. This lowers the melting point, and your work will be so much more easy. Instead of adding new solder, a bit of flux also does the trick. Great repair Ivan.

Even though I've never worked on one before, I pretty much expected you finding an open frame relay with an open circuit coil. For exactly the reasons you stated. I do have those in stock, they're commonly used in Mercedes relay modules. The most common being the "over voltage protection relay" which results in a crank no start (those with KE-Jetronic will actually run but be lacking all enrichment such as cold start and acceleration, which is initially confusing when you're used to electronic fuel injection), or an ABS fault due to missing ignition power to the module. Yes you can get aftermarket modules but the experience I've had with them means you're better off doing what you did if the original open frame relays aren't readily available
