Hi everyone.



We still have the crappy weather here with rain Rain RAIN!! I have been patiently waiting for the humidity to go and the rain to stop long enough for me to ceramic coat my headers and pipes, let it air dry for a couple of hours and then install it and then get it on the road to bake it. 3 weeks… YES 3 weeks I have been waiting for this. In the mean time the bike has gotten great attention. Suspension renews, Brake renews, Starter renews among other stuff and now this.



I was just cleaning up some connections on the bike that sit under my seat. They are the connections that go to the back tail and signal lights. I also did the PTT button and the fuel sensor connection as well. While doing this I was thinking that some of you out there probably would like to know about this process. It really does a great job of cleaning the corrosion off the metal pins and creates a “Like New” electrical connection. Very little effort is needed and you don’t have to take any pins out.



You need the following:



A jug of CLR (the actual cleaning agent)

Dielectric grease

Q tips

Regular tap water

An old tooth brush (or from someone that you don’t like)

A couple of small dishes or containers

Eye protection from splashes

Caned or compressed air

Paper towel or a clean rag



I have been using CLR for years to clean connections. Here in Canada we can get it at Canadian Tire and the “Home Depots” of the world. Here’s the website for CLR.

Basically it is a mild acid and will almost instantly bubble off and remove corrosion and grime off of connectors. When I say connectors, I mean electrical wires as in a wire harness and nothing to do with connectors on a circuit board.

First of all, disconnect the connector in question and put on your eye protection. Safety first! I don’t use gloves but some may want to. If I were to have my fingers in it for a prolonged period of time then I would. A few seconds here and there won’t hurt.



Basically, I pour enough CLR into that blue glass dish to submerge the connector in it. You want it to be totally submerged. Watch the connector. It will start to bubble in an a few seconds as it cleans. In 20 seconds or so remove it and let it drain and put it back in and swish it around.



If there is grease on the connector you may have to brush it with the tooth brush. Take it out in about 30 more seconds and take a quick look at the metal contacts. If they look good, submerge them in the other dish that has water in it. I used the green container with lots of water. This will dilute and neutralize the CLR. Just swish it around for a few seconds.



When done, take it and blow it out with the compressed air. Dry the exterior off with a clean rag or paper towel. Inspect the contacts again. If they look good, you’re done! If not, dip it in the CLR again for a few more seconds and repeat the process.



Don’t keep the connector in the CLR for prolonged periods of time. It will eat through the metal!! A total of a minute or so is really all you need. If it does not come clean by then it’s not going to.



Do both ends of the connector and apply the dielectric grease with the clean Q-tips and put them back together. The dielectric grease is a must as the plating on the connector pins will be compromised a bit (it already was due to the corrosion though). Don’t be stingy with it and get it deep into the female connector.



You’re done… move on to the next. It’s that simple.



Here are a few pictures of some connectors and pins that I was doing. The before and after.



I hope this helps someone out. Intermitted contacts are proper pain in the butt. This will cure those problems if it is connector related.

This is just a demo picture. I placed this connector in a small dish of CLR and let it set for 30 seconds and then rinsed with water. No brush was used. This was a part from the 3 yellow wire connector we all love to hate on the 1100’s and 1200’s – the stator connector.

This was an actual connector I was working on. It’s the tail and signal light connector. It really came clean. Again… no brush. It was only CLR, water and compressed air. This is the front…

Did you pull the connectors out of the plastic plug or is it safe to soak them as well?

You can soak the connector housings as well. But make sure the connectors are unplugged from their mates.

JBz,



Yes… The Cotton Tail… (their not sterilize either!) Hmmmm.:cooldevil: There is no mixing with the CLR. Just straight out of the jug.





AndyB,



The plastic is fine to soak. CLR is fine on the plastic.





Rudy,



Your 100% right. They do have to come apart to get clean. How else are you gong to admire you work! ;)







AQUAMAN,



You would think that with a name like that you would be my neighbor!! %!&#*% rain!!! Arrrrrgh! :X



I did use Lime A Way once. I think CLR and Lime A Way are close to having the same formula. It worked well too.

Hey Scooter 7,



I’ll start a new thread on that one. Basically, I have removed the pipes and have sandblasted them. They were quite rusty… the chrome was all gone but were still solid. I am going to spray them with ceramic paint.



Like I said… I’ll do another thread with pictures.



I just need 3-4 hours without rain or fog. Where is “heck” is the “darn” sun????

That's where my tooth brush went to! Well I never...

Great Idea Mr Magic Fingers, CLR is magic. Where I work we have a large staff and in the coffee room the coffee makers are always on and many times they are left on with little or no coffee in them so the residue bakes onto the bottom of the jugs. For years when they got uncleanable they were tossed out until someone had the bright idea of cleaning them with CLR. Works like magic, splash, swirl and puff it's gone!!

Yes CLR is available in the states in the same bottle as in Mr Magic Fingers picture. It's in most store around here.

The plastic housings of the stator connector on my '85 1200I were discolored (brown) exhibiting evidence of over heating. I cleaned out the grease the serviceman previously applied with WD-40 and Starting fluid, ether and Q tips (no smoking!!!). I then used a simple emery board used to file fingernails. By peeling off the finer side of the board it slid into the connector with enough tension to scrap the crap off the connector. I repeated until the extracted board remained clean. Applied fresh connector grease, whaalaa.

While doing so I came to the realization that the "services" provided previously consisted only of a fresh application of grease. The connectors were NOT cleaned. You should have seen the black/green crud that scraped off the connectors. No wonder the connector was on the road to frying. I will definitely try to find and use the CRL next time. The CRC I had on hand did nothing to remove the crud. Lime Away could work too. What about vinegar?
