Hi all.

Im just fitting a acewell speedo ect. to my MK .

Was just wanting some advice where the best place is to fit the magnet and receiver was.

Any photos would be a big help.

Cheers.

I mounted the sensor on the back of the gearbox and the magnet on the prop flange. once calibrated the speedo is good. fuel gauge and temp, not so good.

Most people mount the speedo magnet and pickup on the diff flange as this does not move about..

My sensor is on the prop just behind the UJ. I used slow setting epoxy and it has been fine.

Fuel and temp gauges work well also.

mounted on rear upright
my acewell uses only one magnet

I prefer to mount the magnet & sensor on a driveshaft as speed is slower & therefore less likely to fire magnet into space! Also saves having to divide wheel circumference by diff ratio.

Myke 2463 if fuel/temp not working correctly, fuel can easily be corrected by using a resistor in addition to the sender resistance to get it to match what the Acewell is looking for (they do come with a resistor soldered in to demonstrate the fuel gauge - you need to remove this to make it work accurately) the unit is also switchable for 3 different resistances depending on your sender.
Re the temp gauge, would suggest the sender is perhaps not appropriately sited??? Mine is absolutely spot on.

Just out of curiosity, the acewell I got of fleabay ( before I knew you did them ) came with a magnet that was mounted in a bolt sort of thing so all I had to do was drill and tap the lobro, is that not the std acewell fitting

If sticking the magnet on, cut the threaded bit off.

I didn't muck about with any complicated calculations for getting the speed settings right. I just used my satnav and a bit of trial and error. It's spot on now.

Cheers for the help, guess this is my job for the weekend.

Russ, thanks for getting me that replacement to me so fast.

Yes the standard magnet comes with a 6mm thread, but most people are far too lazy to drill & tap a thread (have to confess to being guilty on this one!) & simply cut the thread off & araldite or similar the magnet on. Obviously it is actually far better to tap a thread & screw the thing in!
