Started when Nemo popped in to say the step was out.
Went round, blipped the blipper and in it popped.. Thought I had just forgotten to lock it and set the alarm.
Two days later it is out again !
Started to investigate.
Found the step button did not work but turning on the inside entry light operated the step !
Also noticed that when I opened up the van on the remote the external light did not come on.

Last night could not sleep for thinking about it.................

This morning I went out and went straight to the only thing that I could figure was common to all the issues.
That stupid ( with a capital STU !! ) extra control box that is fitted with the Sargent system.. The EM50

Undid it and lifted it out.. As I did it the step started acting like a sodding semaphore flag..

Removed all the plugs and refitted..
Everything started working as it should..
Not having the time or the inclination today I left it at that, but I reckon it was not a bad plug joint but a bad solder joint on the actual board somewhere...
I can see I am going to have to remove the unit at some time in the near future, remove the board and go over all the damned solder joints to find it..

One thing is sure about the Sargent system.. It does keep me busy and my interest piqued !

Hmmm,

As a fellow Auto-trailer and hoping you don't mind me commenting on your bus step. I would just like to say, we got similar problem with ours, so,,, thinking long and hard, but not too hard, I decided to go out, buy a double step and tie the Bus step back with a cable tie,,,,, and then had another beer.! Sorted.!!

Seeing what you have said about the EM50 I think I will give it a try.

Thanks for the info.

There is a known issue with a faulty batch of "polyfuse" in some Sargent panels.. Creating an issue with step operation.
This does not sound like that problem BUT may be worth checking with Sargent as they could tell you if your unit is one of the suspect batch..

When we had a similar problem with our step I did the same as you and narrowed it down to the EM50 and found a little bit of "furring" on the 'jumpers' that pull out to change the configuration..
As you have done, I pulled them out and put them back and that was it.....The only other thing that springs to mind is that our table is stored right behind the two switches ( step and inside entry light) They haven't got shorted together have they ?? Good luck. Mitch.

You will have one somewhere... It is not where you expect it to be !
What model charger do you have fitted ??

Anddddddddd

for all those with a similar problem, I offer these words ..

CHIP CREEP !!!!

Not 100% sure yet but I think that is what the problem was.

Disconnect the leisure batteries
Turn the unit over.. and look for a couple of 16 pin chips in carriers ( see note )
Mine had suffered cheep creep and were trying to exit their carriers.
A firm push down on them reseated the buggers and so far no more weird happenings

NOTE
In general I have found the Sargent system extremely well made if, as mentioned add infinitum, vastly over complicated.
However, mounting chips in carriers in a mobile environment that will have massive temperature changes is, in my opinion ( and with my electronic design engineer hat on ) the most stupid thing possible.
Quite obviously the chips ( proly simple TTL logic things ) have in the past caused failures.. It is very nice to mount them in carriers so fixing the panels is nice and easy, but sorry, these things are built for a VERY specific use and with the carriers are not really fit for purpose.
Come a bored moment I will remove the carriers and solder the chips in properly ( not something most folk can do I appreciate but def something that should be considered if you have the skill set )

I've just read all this, just for something to do. How complicated does a step have to be?
Why does it have to be controlled by a Sargent unit with it's associated complexities?
My old Cheyenne has a manual step which unfolds with no real effort at all, apart from reaching to it with a hand. A little tap in the right place with your foot & a spring takes it back into its parking place. Simple!

Sod sod bugger and sod..

Was absolutely convinced I had found it .. been as good as gold for the past week.. Guess what..
Yup, its playing silly buggers again !!!!
Even if I end up completely defeated there is absolutely NO point in getting a dealer involved as the issue is so random...
They could have it for months and still not find the problem.

I will be back out there again tomorrow and starting again.....
More updates as and when................

Jaws,
U still having problems with that em50whatever.? Try what I did, pull the step fuse, cable tie the step back in place. Go buy a double step, and heypresto, Job done.! Then go pour yourself a nice cup of Punjana, or a G&T, or a B&C, and R-E-L-A-X my boy.!

Me thinks you must be a glutton 4 punishment, don't blow a gasket. A.? :banghead: :madder:

Sorry.!

Errrrr... guess where I bought the van from !! And they could not fix the original issues before I collected it..
They actually had to do a bit of a bodge to get the gas igniters to work ..
Having said that I would happily recommend the firm to anyone.. Nice folk who really try..

Sooo.. Latest update..

Took out the '50' again and this time used a solder sucker to remove the solder from every joint on the board that did not look perfect.. Then resoldered them..
Removed the chip carriers completely and fitted new ones ( standard dil packages so had them on the shelf .. I suppose I SHOULD have discarded the ruddy things completely but if the board does have to go away I did not want to make life more difficult for the next poor sod who works on it !!

At the moment it is all working perfectly again, but I am saying nowt as it worked properly for a week last time I thought I had sussed it out !!

Still no joy on either of the new numbers you sent me I am afraid, but thank you for trying :)

Had another look at the maps last night..
There is one thing outside the M50 box that I had not considered.. The step and the entry light share a common earth.. so that will be my next port of call when I start on the thing again...
