Tam &Toby do Europe ...Take two

Well it seems disconnecting the room sensor didn't solve my heating problem afterall it's still cutting out .

Fecking heaters...why can't they make campers with systems that work every bloody van I've had there's been heating issues

Just about everything else has gone wrong with my van over a few years, but it is 19 years old, so maybe the heater will be next. Currently fridge not working on mains, there's always something!

When we lived in Scotland we were led to believe that the Scots didn't need heating and when us mear southern mortals were out wrapped up like mitchelen men they where wandering round in T shirts.

Are you getting soft in your old age?

Here is your nearest repair place Tam, might be worth calling in. Bob.

No im just trying to prepare for the culture shock I'm heading back to lol ...I've been used to warmth for months

Thanks for that but typically it's in the direction I came from I'm heading back in to the tip of Portugal before then heading towards Leon

Oi
It’s finders keepers ??

 

[Razamataz]

So sorry meant to post after Milos biggest ever bone find!!?

It's annoying as it does seem like it's a voltage problem with my heater, when I tried it at 8am it kept cutting out as soon as the fan gets up to speed , red light comes on , heater clicks fan stops then restarts and just keeps doing the same thing. Panel showed battery at 12.8v


Now suns out panel shows battery at 13.7v
Heater will run no problem. No red light and fan runs continually at full speed lots of hot air.

Now according to manuals the cut of voltage is 10.4v so why is it playing up

I don't know if there's a voltage sensor or something..

But obviously I don't need the heater in the middle of the day when it's warm and sunny it's mornings and nights when it's dull dark and cold. ?


I'm gonna try it again just to see but was running a good 15 minutes there at full whack and didn't cut out once

 

[tacr2man]

Try when cold in morning , start vehicle so voltage goes up then switch on heating . See if works ok noting panel voltage . Have you tried checking earth and supply voltage with a meter at the point of heater pcb etc.
I had similar problem with RV heater , corrosion on connector of flame failure sensor .

I've just had it running there for a good 45 minutes and no issues, panel showing 13.2v throughout...No red light and no fan cutting out.

I will need to get a battery for my volt metre as I've left it switched on again and battery is flat ?
Tried phoning truma also but no engineers there at the minute and the woman was just trying to get me to make an appointment for when back in UK.
I'll try it again in morning without engine running and then with and see if it works.

Well I've sent off an application to a campsite in oban for March to October, I had to phone the guy and ask as I couldn't provide a reference from previous employment as they've gone bust but he said anyone I worked with would be fine it was merely to establish if someone was a sticker and not someone who would leave mid summer and leave them in the lurch etc
Explained my situation of wanting to work spring summer and travel winter time and he seemed very positive about that so will see


I haven't filled out an application or had an interview in 14 years so very rusty and I hope the application is ok

Time will tell I Guess

 

[Northernraider]

So we had a bit of a walk around town earlier and through the forest that's attached to the aire..it's a nice spot this I'd recomend it

 

[Al-Di]

Tam, can you put a direct feed to the boiler(hab Batts), we had a similar problem a couple of years ago and this is what truma told me to do, and it worked, it was something to do with the low voltage relay in the ebl,

I can certainly try it at somepoint to see if it makes a difference

But it could well be something like that as I've other issues with my ebl needing looked at

Where are your last photos of, Tam? I really like the look of it and nice to see green grass in Spain!

Stay where you are then. I'm stuck in Devon , it is freezing by my standards + cloudy,raining.

Back to heating. could well be a dodgy connection or even cables undersized ?
My mate bought a MH with diesel webasto heating/water & it wouldn't stay on , as you describe. Took it in fr service & they said it didn't need one but changed the cables as autocruise installed originals were barely adequate when new. Never missed a beat since.

Weird how it works okay when the battery voltage is higher though.

I suspect but I'm not positive but i think a thr probs are either ebl or control panel related as I have other issues with both.
I need both looked at by someone with better electrical knowledge than myself.

I have the heating running just now and while it has clicked off and on several times at the start its now running consistently although the red light is still flashing ? but if I run anything else even a tap it cuts off despite the panel saying batteries are 12.5v and 94% capacity at the minute.
Heater drawing 4.4amps

I need to get battery for my volt meter today so I can check voltage at heater

What’s going on in photo 9 above, look crowded- well by your normal photos it does!!

 

[Lenny HB]

With the heating, it won't be volt drop on the cables as Hymer do proper wiring.
I would try and follow the cables back from the heater to the supply checking all connections for signs of corrosion or over heating ( due to poor connection).
The heater connections are not in the Elektroblock they bypass it so you can have heating on with the panel turned off.
Near the EBL there will probably be a small bank of blade fues with a couple of 10 amp & one or two-day 2amp fuses. One of the 10 amp fuses will be the heater, the other 10 amp is for a sat dish if fitted, 2 amp for electronics on the fridge.
Also check the fuse on the PCB of the Truma make sure connections are good.

Just remembered on our first Hymer a 2008 one with 6002 had an intermittent problem used to cut out and red light flash.
I unplugged all the connections on the PCB cleaned then, it never went wrong again.

Okay I've just got a new battery for volt meter .....putting it on the live and neg feed to the heater at present I'm getting 14.3v
Because it's now sunny the main control panel shows my hab batteries at 13.4 and my engine battery currently at 14.6.
I've had a look around heater and around ebl and can't see any fuse box that isn't actually on the ebl itself ? tracing the wires isn't easy either as they go under the floor in a bit of conduit pretty much under the heater and being just a brown and blue wire not easy to see where they 're emerge

Heater works fine when sunny like it is now or with engine running ( tried that this morning ) no red light or cutting out ............but otherwise the red light is flashing and heater cuts out as soon as fan gets up to speed.

 

[Onemanandhisdog]

Sounds like you need to measure voltage again when you have the issue.

 

[Northernraider]

Yeah need to measure it in the morning or once sun has gone down.

But I'm fairly certain I did this before and it was always the same voltage as the batteries.

I think there must be a voltage sensor on the heater somewhere that must be faulty .
As how else does it work fine when getting that boost from engine or solar.

Also not sure of the ebl or control panel as panel shows only about 4 amps going in when engine running yet shows batteries at like 13.4v or something

Hate electrics lol

Right Mr lenny sir I have a question...If the heater bypasses the ebl how come I've a fuse on the ebl says heizung and if I remove it the heater doesn't work at all ?

OK your one is wired different to the 3 Hymer's I've had.

 

[Northernraider]

Yours have all been newer so maybe different on newer models.

So do you think there might be some sort of voltage regulator inside ebl or something
Although that don't make sense either as checking at heater it's reading plenty volts

Its an ebl 101

[Lenny HB]

No just straight hrough via a relay, contacts could be carboned up giving a volt drop also check plug & socket on EBL.

So here's a few pics of yesterday's stops
Mirando do doura and some wee village I stopped overnight at ....I'm in Portugal just arrived at braganca.
