vamo o ring/ grommit issue 0.0 ohms reading - help

[clivealive1]

hi,

I have the famous vamo v5 o ring issue 0.0 ohms reading.

I have the following questions / comments.

1/ I can still see the o ring in side (original) only had vamo a month.  seems quite thin though.

2/ I cleaned the connection as it was dirty

3/ I have tried all the normal pulling the pin up or down with no change from the 0.0 reading.

4/ The ring seems to be around the pin not under it. is this right  (have tried pushing ring down with no sucess)

5/  what o rings do i need to order. if i need to.

6/  I have some ego batteries will they have a ring i can use.   or what will.

7/  what else can i try ?

 Thanks

I have the vammo v2 and it had the same problem I just used a normal small black o ring from b nd Q and it has been working great for the last 6 months

It's not an O ring, but it might be now.
It started life as a small grommet insert that fits down the hole the pin
Sticks out of.
The problem comes when you tighten something with a long positive pin to the top
And do it up spotlight that the vamo positive pin cuts the top off the grommet leaving
An o ring.
You can repair it with a grommet from an old ego, it's just a bit fiddle getting it over the
Positive pin on the vamo, the least fiddle way is if you can remove the pin then resolver it
Afterfittingthe grommit, but it can be done without if you don't fancy resoldering it.

I hate autocorrect!

I found that by using an o ring it solves the over tightening issue as the o ring is a bit thicker

The problem is an o ring will not insulate the opening the positive pin passes through,
you are just hoping the remaining piece of the grommit stays put.
The ego grommets are normally a bit sturdier and fully insulate the pin.

assume you remove the grommit from the ego in a simular way you get to the vamo one ?

I used a grommet from an old nova head (three times now). Worth having a look at this.

take batts out! lol then use a small sharp instrument and work it out,come out about 5ml above head, then use a safety pin and flick old one out, what i had to do is support the pin with scissors[nail ones] then pull grommet over pin and then used a small screw driver to push it down,then push pin in but not all the way ,then i screwed an atty on top to push pin in fully to corrrect height............pull any old clearo apart at bottom where pin is pull that out theres a grommet there

running out of ideas here need some new ones i think
took a gromit from pro tank , couldnt get it on then lost it on the floor somewhere.
tried an ego grommit but couldnt get it on so cut a slit to get it on, but sadly still not working.
mr grrrr

Hi clivealive1, first off if you purchased your Vamo from a reputable UK vendor then you should have an easy warranty claim (if you put the original grommet back).

The best repair is 5mm heat-shrink (8mm flat) over the pin and wire, shrink and trim, then a 2mm ID x 1mm C/S O ring under the lip of the pin.
It's easiest done with the pin removed but can be done 'over the pin'.

I wouldn't bother with a standard grommet as you will end up doing this again in less than a year.

PM me your address and I can let you have a couple of O rings and some heat-shrink, gratis.
If you aren't having any joy then you can send it to me and I'll (hopefully) be able to sort it for you.
No charge, I just ask that you cover the return postage.

thanks PM coming soon.
i wouldnt wanna remove the pin though.
so i put the o ring on then i put the pin and wire inside the sink is that right ?
iam not thick honest lol

will it still work with just a 2mm ID x 1mm C/S O ring and not the shrink ?
