hi there guys,

 

How do you clean electrical connectors? I've developed a miss-fire after changing the loom and deleting the air-con and am starting with bits I've replaced to find the fault.

 

Cheers

I had numerous electrical problems, especially erratic tick over,

I cleaned my harness connections with acetone, (after scraping off the green verdigris) she now runs perfect!

Be careful to use sparingly and test on a small area first, as it can attack certain plastics etc'.

I used a small artists brush to apply it.

go to one of those really cheap shops that sells everything. got myself a complete set of green gem 5 mini files for a £1. clean the spades of connectors with these, then spray with some ambersol (spray contact cleaner for electrical stuff)

best £5 you will ever spend. plus should be part of a zed toolkit.

check you havent overtightened the ecu connector, i did on my one and i lost an o2 sensor!! slackened it off and the car ran sweet as a nut :)

You can buy a contact cleaning pen there the nuts and only cost a few quid they use fiberglass inserts to lightly scratch the grime and carbon away we use them for cleaning up burnt/carbonated relay contacts on lifts

Cheers for the ideas guys, I'll try them tomorrow.

I use a contact cleaning spray that's slightly acidic. It bubbles away all the crap and leaves the connectors nice and shiny again.

Do you remember the name of it?

and if all else fails mate, use a combi tool with a bit of scotchbrite (works surprisingly well)

Can do better than that mate; http://www.toolstation.com/shop/Automotive/Lubricants+Sprays/Contact+Spray+400ml/d60/sd2795/p81507

 

Don't let the cheap price put you off, it's great stuff :)

Protects them as well, even better, cheers

I used this stuff in all my connectors when i fitted a new loom , stops the green corrosion happening , i read it was developed for the marine industry to combat electrical issues in boats , Once you,ve got them clean fill the connectors completely and reconnect , should have any more probs again ! happy days :thumbup:

any luck rob?

Hi Gaz,

 

Yeah mate got it sorted. The ECU connector was a bit tight so slackened that off a bit. Cleaned the connectors and I have a feeling the PTU connector wasn't on properly. Anyway she runs lovely now.

 

How's things with you?
