Looks like I'm going to have to have a go at this myself, anyone with any pics or info ( I have been fortunate to receive some which details the main problem areas and the Tants to replace) I would appreciate. There doesn't seem to be any EMER repair manuals available (non-listed on VMARS) but I am quite confident I can do the job. The spares are easy and cheap. I will use the "dead" IBMU as a guinea pig before attempting the "good" one.

As said, any further gen will be gratefully received.

Fortunately I work for an electrical engineering company, so help is available.

One thing that has been suggested is to heat the legs of each suspect capacitor just in case its a dry solder issue. Anyone any thoughts on the merits of this?

My intention is to document everything I do with pics etc, for the benefit of others facing this problem.

Hi Iain

Now I know exactly where Thorpe is, not far away, many memories of the area back in the 60's travelling the highways and byways with my Father on his business. Who he didn't know as farmers in the area weren't worth knowing. Many a night spent at the Leagate Inn, watching the F4J Phantoms scream off the runway on QRF at RAF Coningsby, the afterburner on F4's was always spectacular as was their noise which they were known for, damned good aircraft though, I remember seeing the last of them in the early 80's. In later years I was at both Scampton and the nearer Waddington as well as being rolled to Coningsby which although not stationed there, I visited regularly.

If VLO is seen before a battery is placed on the tray it is likely the supply voltage is (or appears to the microprocessor) low - can you measure the supply voltage with a meter ? I dont know how low it can go and still work - when I had one I always ran it off a Clansman 50A mains PSU at 28V and never tried with batteries ?

 

I have just moved house and my workshop is in boxes and distributed across the van, the garage, and three different storage facilities so I'm not really in a position to take on the repair

 

If you are in Lincolnshire it would be worth a word with Colin G4DDI at Thorpe Camp if you ever go there both about the repair and joining VMARS

 

Also note that the IBMU will refuse to charge very flat batteries - although my recollection is that it sees them as short circuit and reports s/c for the relevant tray position - you need a DCCU and slow charger tray to safely get them back to a sufficiently charged state that the IBMU will run a reconditioning cycle on them

Hi Iain

Thanks for the excellent info.

The IBMU was connected direct to the vehicle supply in this instance, my Hawkers are in tip top condition and fully charged but I thought better to check it out direct from vehicle output. I measured the output at a steady 28.4v, which is what it always on my vehicle. This I believe is bang on what it should be. This being the case then for some reason the microprocessor is deciding its seeing a low voltage supply? This is slightly more encouraging news for me so maybe it's not too dire. There appears to be no output from the IBMU into the tray but that will be because of the alarm I assume?

Where is Thorpe Camp? I am at Melton Mowbray, not far from the Lincolnshire border. Do you have a contact email address for Colin? Sorry to hear you cannot take on the repair at the moment, but I am in no rush at present.

Importantly I did not know that IBMU's will not charge totally flat batteries. I have a DCCU and charging tray so I will bring a couple up.

It's probably worth checking the fuse with an ohm meter or continuity tester out of circuit - if blown there is a quite considerable chance that a replacement will also blow due to a fault within the IBMU. I think PTS Norfolk (aka GTEN98 on e-Bay) are the most likely source of spare fuses in sufficient quantity to be able to risk some during repair.

 

If it is completely dead and not doing the power on self test then I'd guess either the internal PSU is faulty, something is loose inside, or the microprocessor board is faulty. I think it would be worth a look inside before powering up with a new fuse in case anything is obviously loose and can be reconnected

Hi Iain

Picked up the other IBMU today, powered up ok & went into test, no problems - I was ecstatic!. Alarmed up, ok so no problem, acknowledged the alarm which then displayed 'vLO' on the LED. After a couple of minutes alarmed again, so I acknowledged the alarm again and got the same 'vLO' on the display. I don't know what this alarm is. This continued and even after powering it down and back up again it continued to go straight into alarm. So initial euphoria replace by extreme annoyance.

I swopped the fuses over between the two units and the dead IBMU fuse is ok, so must be major problem with that unit.

So, this now leaves me with one dead IBMU and one that powers up but now goes into alarm mode and 'VLO' as soon as it is powered up.

All I want is a gwo IBMU.

Unfortunately I am not a member of VMARS (I should be) so cannot access their database.

Is there anybody who can access the spares and has the knowledge to repair these things?

Regards and thanks for yours and MatchFuzee's help

What seems to be wrong with the IBMU ? I havent ever seen spares for them apart from the battery trays and link cables so you are very likely to end up consuming another one for parts - as a microprocessor controlled piece of kit they are harder to debug and fix than the radios if the issue is non-trivial.

Hi Iain

It's dead, no power up. Supply checks out ok, fuse is present (but no way of checking as no spare).

On power up they will go through self test if all ok but nothing happens with this one when switched on. The fuse is a 10amp v. small if I remember correctly but in my experience it's very unlikely to be that, BUT you never know unless you have known ok spare. Unfortunately I don't.

Tomorrow I may be able to check fuse as by chance I have come across another IBMS, at cost I admit but not too bad.

BTW you are right, they are v. difficult to repair if broke, parts are not easy so BER is often the end result unless you have a spare. Potentially I have a spare but who can do the job as I wouldn't know where to start.

Will update.

Thanks very much for your help.

Hi,

Can anyone repair Clansman IBMU's? I've got one I'm not sure what to do with, either sell as is for spares/repair or get it repaired.

Any help would be appreciated.

Bob

Dear all,

 

You may or may not be aware of my situation - please see my introduction thread - http://www.hmvf.co.uk/forumvb/showthread.php?48089-Hi

 

I was hoping someone could help me identify and give me an approx. value of the following items. I've setup a Dropbox gallery which can be found here - https://www.dropbox.com/sh/uue35avte3g4gr7/AAB067f3rg1dWXmq5kG75O49a?dl=0

 

As you will be able to see there are 31 items, a couple of them have photos from different angles. Some of it is quite obvious as to what it is, such as the First Aid kit and the rucksack, but values or offers would be appreciated.

 

All of this stuff will probably be going on eBay once I have an idea of what to list it as.

 

Many thanks in advance, I hope that some of you can help me.

Hi Edd

Sorry to here of your loss,

For me there are two items I would like to offer a fair price on and will send you a pm.

Regards

Bob

Still looking for one of these.....

There are now 2 on MILWEB, £1300 & £1650, both look very good. I believe these are now becoming investment pieces which is what's driving the price up so fast. Ok so long as They don't make them illegal.... watch this space.

Regards

Bob

I haven't seen any, Bob but he has 2 large sheds full of spares I won't find out what's in there until nearer the auction date when we start sorting through them.

Hi John,

Many thanks for the reply, I would appreciate if you could keep me in mind re the seats.

Regards

Bob

There are 6 to choose from Terry including at least 1 Flying Pig. Postage may kill the deal though.

Hi John

Are there any FC101 FFR's?

Also more importantly I am after a pair or at least one FFR Unitary Radio Station rad op seat, pics below from early in the year by Wayne;

In anticipation,

Regards

Bob

I have a 1980 Land Rover Lightweight FFR (24v) and I'm pretty sure the generator bearing is on the way out!

 

Are these available as a seperate item or am I going to need a new generator?

 

Any help appreciated and if anyone has the relevant EMER pages they could copy for me, I'd be happy to cover your costs![/quote

 

Hi Peter

 

See my posts re this, have been there but came up against a brick wall re one of the seals. The bearings are no problem, but do the lot whilst you have it stripped!!

 

BTW, I still have the new one in storage! Grease the main bearing by removing the screw cap and push the grease in with your finger until you think you have enough in, refit screw & run engine & repeat if needs be - look in the hole, if its still got grease in leave it alone . Don't over do it or f**ked Generator.

 

If you have the belts off, or slacken them, then check for play on the shaft, you'll soon know.

Good Morning All

My apologies to you all for this belated introduction as I have been a member for a month and it is high time I do this. My name is Bob and own Lightweight 19 HF 27 and Sankey Trailer 42 ET 39 which is currently under restoration. My past life has only reinforced my lifelong passion for Lightweights and green oval badge products in general together with military vehicles as a whole. I've got a fair amount of experience in restoration of military Landrovers and some of you may know of me from elsewhere and I look forward to sharing and helping where I can. That's it for now.

Regards

Bob
