V8 throttle pot

[hallsie]

Despite flying through the MOT yesterday, the beast let me down this afternoon, just after having a 'play' with an M3 on the M20!

Looks like the throttle potentiometer / position sensor is the fault so Im going to take it to bits tonight...

Just in case, who knows where I can get a spare from?

If it's the big one (2" diameter), they can be repaired.

[hallsie]

47mm diameter which I suppose is near enough to 2"!!

Ill have a play tomorrow and see what happens, if not Ill be calling you rob.!

Stu, as discussed you might get lucky and repair it. A quick test before you remove it put a decent meter on the connector and check for smooth variation in resistance when you operate the throttle, good luck and give me a call if I can help fella

Last one I swapped due to duff, was fine and it was the connector, as had to swap them due to new one having the different connector.

You can also check the voltage with it connected. to test operation.

Thanks Rob, Im still sat in a field in kings lynn, norfolk, but the wife said it arrived safely!!
Leigh, Chris, I put a meter accross the plug and the readings were so irratic it was silly.

Im hoping 5 mins and the one from Rob should have it working, if I ever get home tonight!!

(some berk has just got himself and his lorry stuck on site and needs to be recovered, but Im that last one on site and need to lock up....... friday the 13th got me!)

Then its strip the alternator......

[carob]

No worries Stu, hope its suitable for you.

Rob

[hallsie]

Thanks Rob, but unfortunately its the wrong type!!!

bkS!!

The one on the right is the one that Rob sent me, (I will return it to you ASAP mate) but its the one on the left that Im after, anyone know what it comes off?

[carob]

Oh st mate, sorry about that.

You may want to try a Land Rover dealers.

Or you coud try Rimmers or the like.

Rob

[Jack Valiant]

Drop it round to me Stu I will have a look at it for you as mentioned, nothing lost if its knackered fella?

Chris

[carob]

Not sure on this but can you not just change the connector/plug end?

I am sure Wedg1e or some one will be along to tell me to stop being a plonker.

Rob

[hallsie]

Im currently looking for the wedgepages to see if theres anything on there about alternators!

Chris, Ill pop round with the timing light about 2 if thats ok?

Stu

[Jack Valiant]

Will be in about 4.30 if that's any good? Drop me a text fella

If it's a flapper system then the one on the right is the correct one. and the one you have fitted is wrong.
So you may want to just change the connectors and use the one on the right.

ETA,
Opps I've just say you have a 2.8 the one on the right is for a v8

Leigh.

It has worked fine for the last 4 months since I got it, and the TPS rob sent works in the opposite direction and is spring returned!
the drives on the shaft are also different.

might think about a way around it tomorrow,,,, my head hurts.

[adam quantrill]

Ramon (I think) posted up a design for an adapter plate and commercially available pot - do a search... I would but I'm off to pick up my chinese...

Chinese digested.... now read this: http://www.vintagemodelairplane.com/pages/Download...

Stu, just for info the old / larger pot is part number ERC 3619 with the 3 pin connector with pins in a row.

The newer smaller version with the triangular connector is ETC 4483

Both are no longer available generally so it's a hunt to find them! You will need the the first one I think.

When replacing make sure that the spindle hole is properly sealed as this will cause a air leak and it's associated problems fella

Cheers

Chris
