Petrol 2.0 2005 - Ignition switch diagnostics with video

[ognob]

New to me bongo, purchased with a few known problems.

Currently I have a cutting out issue, don’t think it’s related to the faulty ignition switch, but having a faulty switch can make restarting when I’m in the middle of a j7nction a bit more exciting, so it’s a good thing to fix as it does need doing

Some days it’s fine, other days it can be 30 seconds of key in and out, back and forth until we get lights on the dash allowing us to crank

Please watch this YouTube video I took

The actual mechanical barrel is fine

Am I right in thinking the bit of beige plastic at the end which I point to that contains the electrics which is simply turned by the barrel.

Can I just remove that beige bit and have a go at cleaning it up

The inside of this bongo is (was) pretty disgusting, lots of dust grime muck fluff hair everywhere

I’m hoping I can just replace the electrical bit without having to do the barrel

Any thoughts?

Your help and time is appreciated, this is our car which we use for a young family so I’m not really using it as it’s a bit of a gamble.

Cheers

Ok I removed the switch at lunch and cleaned it up

Was packed with grease on the terminals inside ? Is this the norm

So far so good, but it could be fine for a few days then play up.

Will update in a few days

Its not a problem provided the grease is the right type!
Needs to be a type that doesn't melt with small temperature increase, nor "burn" - i.e produce a carbon deposit with arcing between contacts.
It can help to ensure that dust and dirt doesn't reach the contacts causing problems, but can also hide and trap dirt if its been added after manufacture.

Another day on, seems ok still

For future reference if you come across this thread with a similar problem, it looks like Mazda 323 has the same ingition switch

Maybe some mx5 as well

Thankyou
