SOLDERING MY METAL DETECTOR

Yup, wont take long. Pretty much parroting you guys ;) Heat your iron up, put a small blob of solder on the tip and re-heat the posts till they flow~ that'll clean them up. On the one with the wire just use some needle nose and hold the wire while ya heat the post and the wire should come free. After that, as said, tin your new wires~ a little blob of solder on the iron applied to the wire, heat then touch the new solder to the wires and it'll flow onto the ends. Make a hook out of the ends of the new wires. Use needle nose to hold the hook to the end of the posts gently. Clean the tip of your solder iron on a damp rag or sponge, get another fresh blob of solder and touch it to the wire and the post till it flows... remove the iron as soon as it does flow *this will minimize the heat transfer to the plastics* and hold the wire still for a few seconds. You can blow on it if you like. Once it sets clean it with a damp rag *I'd use alcohol on it as this will remove the heat quickly and clean the flux from the terminal.* and to seal the posts a bit you can use some nail polish or a touch of rtv. Should be solid then.

Sucks what happened to the cord~ I'd probably take it apart and re-terminate it then re-seal it myself. But that may be a bit beyond ya so you can patch the area over with a good rtv- red would be best- and then tape the area. My thoughts.
 

I do several of these ikelites when making the Excalibur battery endcaps and solder the little 9volt connector, Being the location and the inexperience of your solder skills I would highly recommend someone else that has the correct iron and experience to take on the task. And do explain the importance of the location. It takes a clean surface, fluxed, then the nipple has to be tinned and this must be done with a iron that can heat it quickly, Then the tinned wires from the 9 volt connector can easily be attached.

The coil cable you should use rescue tape or the liquid electrical tape.. not ET, loosen the heyco fitting, pull it back out of the way, clean up the area, then Rescue tape/liquid tape, then refit the heyco fitting, after dry if needed, make sure it is tight, it clamps a rubber seal around the cable and more then likely years of being clamped, the cable will be crimped.

And the damage to the control box itself will need some special care when repairing the battery door cover, seat. I get home from the beach I will check out my CZ's seal. This will need to be done with plastic repair....and a dermel tool will be needed. From what I can see if it has a flat surface you maybe ok....after all is complete, button up the 2 cap screws, put it in a 5 gallon bucket with tap water and do the 5 min, 30 min, 60 min, then 2 hour water test....

Best of Luck n Be Safe...

still have not tackled this as of yet waiting on the 9 voly battery connectors to come.no body said i have to use flux on the nipples?is this mandatory?also wondering about the silicone grease for the gasket.i see silicone paste on ebay but its not clear whats the difference?is the clear better or?if i dont get it from ebay does walmart sell this stuff?thanks-

Unno if Walmart has it...they have a very poor soldering section all full of garbage.
 

Flux serves as a heat transfer medium, do as dancer said, load your solder tip, that will help in the soldering...I don't use the silicon grease on the CZ's gasket, but a very, very light coat might not hurt. You can get it at dive shop (Trident) or (McNett), lowes sale plummers grease, I use Dow 111 on the excaliburs o ring seals. Not silicon paste, that is used in heat transfer.

Don't worry about the flux. It is contained in the rosin core solder. You're confusing it with the grease to waterproof the box. The point he was making is to have the post as clean as possible ie, remove old solder bits of wire etc.
 

thanks guys for all the tips and walking me through this as soon as i get the battery clips i be ready to tackle this.i just hope i can remedy the battery compartment so it stays dry.otherwise i'll have to send it in and sink another $300+ because then i'll have to upgrade to a 10 inch coil into it and have it converted to a cz21
 

:) What Rob said about the flux... don't worry about it.

A little bit about solder and flux~~
Flux aids in transferring heat but is more important as a cleaner. Flux cleans the surface of the metals being tinned/soldered by removing dirt oil and oxidation on the metal surfaces prepping them so that the solder can bond to the metal. Most electrical solders have a core containing flux~ your rosin core and acid core solders.
Flux pastes are more commonly used for large jobs like joining pipes or when you have a non-flux solder. The cleaning action of flux comes from its acidity which as stated cleans the metal like an acid bath. Rosin flux has a very low acidity and tends not to corrode metal parts after use~ this is important in electrical work. Acid flux is, as the name states, high in acid and is used for heavily oxidized metals as a more aggressive acid bath is required to prep the metal surfaces for bonding. Acid flux is generally not used for electronics because it will corrode the metals over time if its not completely cleaned up.
Its always a good thing to clean soldered surfaces after the job is done to remove excess flux. Rosin can be removed with alcohol and a little scrubbing with a stiff brush~ I use an acid brush with the bristles trimmed down so they are stiff and blot with a rag after. Acid can be removed the same way but is a bit more difficult to remove.

As to silicone grease you may be able to pick some up at your local auto parts store.
 

Best Solder.............

............I have found that I use for all my electronics, wiring, for all my projects including my metal detectors is sold by
Radio Shack. No mess, no fuss, solders beautifully.

Don't go looking for this type of solder at Walmart, Home Depot etc. All they carry is solder for plumbing or solder for electrical contractor work
using a torch or 600 watt soldering gun (iron)
 

FLUBBED OUT

sorry guys things just did'nt work out.i ordered a new soldering iron,9 volt clips and some solder.i gave it the old college try today and soldering iron just did'nt get hot enough.dont know why.would'nt even melt the solder.so i'm throwing in the towel.back it goes to first texas for the upgrade.i hope its worth it.thanks for all the tips though.nomad

If you want to get into soldering buy a solder station. It should last you a very very long time.
 

You did not flub it, it is not a easy task for someone inexperienced. Send your machine in and they will fix it, good thing about water / beach hunting it will pay for itself in a short time. If My shop was not closed for the season I would take on your repair.....Best of Luck, and dig us some treasure to look at when you get her back!!

I had a soldering station before they foreclosed on my house and lost it some where.now I'm livin out of my van.so I'm livin on the rough.so I cant have all the tools that I need to do repairs when they come along.

How do you receive mail then?

Sorry it didn't work out for ya. Soldering is a skill like any other and requires a bit of practice and experimenting when you don't have someone on hand to guide you. Luck with your repairs and hope you score enough to offset the expense. Keep swinging.
