My electric step is playing up, it doesn't fully extend or retract without a bit of help, it's not stiff at all. It may be a stripped gear or general wear in the link and drive shaft. Looking on the spare parts list it shows a spring No 10 on the picture and there is not one on mine so wondering if that is the problem. If anyone gets a chance and have a Thule V10 electric step can you have a look to see where the spring goes. There are 2 versions of this step 2013 spare parts list for V01 and 2020 spare parts list for V02 that does not show a spring and my van is 2013 so I would have thought it would be the V01 version of the step I have.

Just had a look under ours Dane, and ours doesn't have a spring either. I've got some photos but difficult to show much of use.
I think you may have the wrong model \ diagram but ......
Ours is a 2013 Savannah (from memory yours is a Mohawk?) and I had to replace the right-hand scissor assembly (4 on your diagram) and the model that I think we've got is (page 6 for English on pdf attachment). May not be but the part did fit for me. -

Cheers Gelly

Yes we would have the same, as you say I must be looking at the wrong spares diagram but it does say for 2013. I have already had to do a welding repair on the brackets as they had cracks in them and the welding heat buggered the nylon bush so I had to drill the pivot out to replace the bushings and replaced the pin with a stainless bolt. Thanks for the PDF.
 
If it's stiff or jammed the motor will struggle then stop. If it's a stripped gear the motor will continue to run when the step stops.

It's not stiff at all the opposite in fact, I comes out ok but the last little bit bit you have to pull it out same going back, but there is no resistance either way. It's as if the motor needs another revolution.

That was the problem with ours. :rolleyes:

Exactly the same as mine but I was able to weld it back together. It's not very thick steel considering the weight of some people and that would be increased as the first pivot is the fulcrum point.

Sounds like a gear might have lost a tooth. Does the motor continue to run if you keep the switch pressed?

Not a bad shout, will have a listen next time I'm up the van.

might be the microswitch needs adjustment or cleaning- part number 7 on the exploded diagram.

The microswitch does nothing when the step is operated manually. It does have a function when the engine is running.

There's a common misconception that the step has one or more 'limit switches'. It doesn't. If you hold the manual switch operated the motor will try to drive the step onto an adjacent pitch in one direction or to the opposite side of the van in the other. The only thing preventing either of those happening is a physical 'out' stop and a physical 'in' stop. The step hits the appropriate stop and the motor stalls. Hold the button for very long after that happens and either the fuse blows or the motor catches fire. And each time it hits the end stop it puts some strain on the gears.

The microswitch. This device tells the buzzer to buzz if the step is out when the engine is running. If you have a clever van it tells the step control relay to park the step when you start the engine. It's only other function is to revert the step to manual control once it has been parked by the control relay when the engine is running.

I stand corrected. (y)
 
If its on a Sargent system, the answer may well be with the main board. The motor only turns about a 1/3 of turn with just a off switch. If it is S argents they will help, providing they are answering. It's a quick fix
 
Diabalo If you have a look at: Step for Sale you will find a lot pictures of the step I replaced. I subsequent had the cracked frame of the one pictured repaired and then gave it a through service. I don't remember a spring.

Cheers for that, I won't worry about having a missing spring anymore(y)
 
Found out why my step wasn't working correctly, I got a toof or 2 missing.

Ordered a new one £30.43p inc P&P on fleabay. Someone on the forum pointed out a while back that it's a Bosch Part No 0390203266 used for headlight adjusting so thank you for that. If you buy the motor for a Thule step it's £50 and it's exactly the same part.

What I don't understand is what controls the motor as it only has 2 wires, is it a polyfuse and what puts it into reverse to pull the step back in.

G*d knows where but I'm sure I read somewhere you can buy a replacement metal gear set for a few pounds. Came across it when I was looking for the scissor assembly. How easy to replace as opposed to the full unit though????
 
I repair our step a few weeks back when the bracket gave way, and then I stripped the gears by stepping on it when it was not fully extended.

The metal gears are for a different motor and will not fit the Bosch motor, and removing and refitting the Bosch motor is a doddle.

Here's an explanation of the steps operation I copied from another source about the step.

The control switch is a DOUBLE CHANGE OVER SWITCH. (Not a double pole change over as this is subtly different) This switch contains two change over switches, one switch changes over when the rocker is operated in one direction and the other switch changes over when the rocker is operated in the other direction. So it carries out a few more functions than just a simple ON/OFF switch.

The Omnistep has a permanent magnet motor. This means that if you reverse the polarity the motor will run in the opposite direction. The switch is designed to do this. The motor rotates in one direction to extend and the other direction to retract.

Nominally 5 amps is the expected working current for the motor. If however you keep your finger on the switch after the step has fully extended or retracted then the motor will stall. Under this condition the current will increase to a significantly higher figure. Sometimes referred to as the “blocking current”.

The Omnistep has two electrical components, the motor which moves the step and a switch that is OPEN only when the step is fully retracted. At all other times the switch will be closed.
 
I ordered the part yesterday off ebay HERE at 1PM it arrived this morning at 9AM via DHL free delivery. I have been up the Van fitted it and now back home. It works as new, so well pleased.

Bought my motor from the same guys, cheapest I could find.
Luckily I had only stripped a few teeth and as the gearing only moves part of a revolution, I have moved the gears to a position were it works okay and will keep the old motor as a spare.
