Hymer, solar, ehu, controller - that should cover it (1 Viewer)

[DavidG58]

Probably another unique to me and my MH issue coming up, knowing that and the quality of my technical posts this will probably not even be viewed by many

sometimes, but more recently most times that I disconnect the mains hook up lead when I start the engine the controller goes off on one telling me mains cable still connected

that is despite me physically checking it wasn't first time at least, on the controller the icon for hook up has a line through it saying disconnected, so why does the same controller say it is

one thought I have had is that it happens mainly on sunny days and I wondered if their could ever be enough output from the solar to confuse the controller the batteries were on charge?

one thing I do know is our charger / electrics bit is not the normal one fitted to Hymers so the solar is not routed through it (EBL?) I think is what I have heard it called

it carries on beeping for ever so is a real nuisance, just thought I have not yet tried turning off the controller to shut it up, that would possibly sort it provided it can be turned off with an alarm active, other than that, I usually turn ignition off and on again and around the third or fourth attempt it normally stops

any ideas, or willing volunteers to look at Chester all welcomed, I will pack extra alcohol

I'll have a look in return for a drink at Chester, I don't have a clue what I'm looking at .
On a serious note I really haven't got a clue, but you'll get at least one reply
Hope you get it sorted

If you invested in my van David you'd have enough solar to power a small country.
Plus a battery bank and inverter big enough for any occasion.

Plus ....

A sensuous island bed.

Hi David

I dont know either but it is a "Hymer" Seriously though I wouldn't have thought it would take the hook up information from the battery state, have you tried pulling the EHU out 5 or 10 minutes before you leave or are you doing that now.

It is becoming a serious consideration, maybe if a replacement mattress is included

Don't forget our Dometic oven which actually cooks real food

but then don't let me forget that stick thingy that needs moving around while travelling

and the driven wheels are at the wrong end

not completely ruled out yet, keeping my powder dry, a few too many rums, or gins for me, nearer the actual point of change might just dip it low enough,

selling mine on here will not be quite so easy

Trading Standards may raise an eyebrow if you described it as 'one careful owner'

I can't remember what you have got, but I'm pretty certain that it's not an EBL. An Italian jobby of some sort, if I remember correctly.

Not that it helps solve your problem. You have my sympathy - that would drive me mad.

Following on from what others have said - turn your inverter on & plug something like a coffee machine into it for a minute. That would certainly stop over-voltage making it think it was still plugged in.

Ohhhhhhhh, such a doubting Thomas.

thanks Simon

now need to buy a coffee maker, closely followed by an inverter that would cope, my 150W job might only try the once

but that is a interesting option

 

[DavidG58]

the really odd thing is that the controller knows it is disconnected as the display changes

I guess it might be something silly like the outside connector has a sensor to say cable still in, (even though it isn't) as opposed to no mains power which the display confirms

One of these might be handy too

 

[canopus]

It could possibly be residual capacitance in the AC circuitry which is sufficient enough to drive the audible warning.

 

[DavidG58]

@canopus

sounds logical Ken, anyway to discharge such a thing?

it does only seem to be on sunny days, hence my thought ref solar input, although it only happens when we have been hooked up

Im sure the electronics experts amongst us may have other views David. Perhaps turning the Control Panel off then on again may do the trick but it seems a bit of a long winded solution.

 

[Dave K]

Just a thought because I experienced similar on our Bessacarr, is the starter battery ok? We had issues with ours which caused a constant beeping coming from the control panel.

don't think this will sort ours, new battery fitted recently and when beeping the words ' mains lead still attached' are on the screen

you can still have a drink without a solution, but ideas gratefully received

Ah, yes, sledgehammer & nut spring to mind.

I have this memory of you wandering striding purposefully across the Misterton site with a huge great Sterling inverter tucked under your arm. Am I confusing things, or did that never find it's way into the m/h?

 

[DavidG58]

@TheCaller

correct in the very last bit, it is now hopefully giving good service in Ambilkate's MH

 

[DavidG58]

My theory about solar input, albeit not founded on anything very technical, still appears to be a strong contender

removed hook up and started engine to move MH back into position this morning, total cloud cover, no alert, possibly just coincidence

will be repeating the check as often as I remember, partly in the hope of being able to try turning the controller off and back on as a fix, will try to alternate sunny and cloudy tests
