Please read this description fully before proceeding. You must send us your turntable for us to modify. Please DO NOT buy-it-now, instead please contact us to arrange to return your turntable and we will send you an invoice once the work is done. The price shown here is for our modifications but there are other options we can explore to get your turntable working which may be cheaper.

Do you have a fancy Heljan or Walthers turntable that now refuses to move? Don't worry you're not alone... they are troublesome!

First things first, lets try a few things and see if this will get it working for you...

If you are seeing Err1 on the display it means the rotating turntable isn't making a good electrical connection to the control board. Try lifting the bed and cleaning the copper coloured circular tracks and sprung pins in the centre (our Loco Go wheel cleaner is ideal for this!)

Err1 can also occur if the IR sensor at the end of the track can't see the turntable edge. Make sure it's securely fixed and the front lens is clean.

If the turntable appears to try and turn then you might have got debris in the gear mechanism. Carefully lift the turntable out of the well and turn it upside down. You'll see two white gears at one end. Follow the silver shaft back to a little grey box which houses the motor. At the opposite end of the motor box you'll see what looks like a large thin grey gear. This is a little optical disc. Turn this by hand (you'll need to do this many, many times!) and you'll see the white gears slowly move. Take a careful look if any of the teeth have debris in them which could jam. Also check the base of the turntable well.

If all this doesn't fix things you may have damaged one or both of the PCB's. We're happy to quote for replacements if you like, however we offer no guarantees it will fix the problem and from experience their control boards are quite unreliable.

So we offer another solution!

We can modify your existing turntable so it still rotates electrically but now by just pushing and holding the arrow buttons on your control box. There's no automatic positioning or calibration, you just hold the button until the turntable is in the right place, then release the button to stop it. The turntable rotates slowly both clockwise and anti-clockwise so it's easy to "jog" into the right place. You'll notice it turns a bit slower than before making it easy to position.

Our modifications still allow your turntable to work with both DC or DCC track and it's wired exactly the same as the original.

In order for us to do this modification you will need to send us your turntable (you don't need to send us the well, just the removable track) and the blue or grey control box. Please use the original packaging if you still have it.

Once we have completed the modifications you will see no difference from the outside, it's all cleverly done inside. Just connect it up and press the buttons to rotate the turntable. As before the turntable can be powered from DC or DCC.

You'll also find our new solution isn't so "fussy" about the slip ring mechanism in the middle being perfectly clean!

Our unique modifications are only carried out by ourselves in our workshops and completely bypass all the original circuitry so no more reliability problems!

Bring life back into your faulty Heljan/Walthers turntable!

All our work is fully tested.

Please note we can now cary out this modification to either the blue or grey control box turntables from Heljan/Walthers. The turntables with a grey control box version goes by various part numbers 89011, 89111 and 89014 but they are all the same control boxes.
