[Speve]

Never had a problem with ours

 

[Kenp]

No problems with the last 3 motorhomes starting engine whilst on EHU.

I learnt that sad lesson many years ago .

However, instead of a big metal box occupying a sizable proportion of a locker I now have a small, modern, smart-charger tucked away under a drawer in a wardrobe: every cloud has a silver lining .

I haven’t had any problems when I’ve started the van whilst connected. The EHU did stop working though after I had driven 25m.

Not had a problem on any of our vans, it looks like a problem with your setup.

 

[bigtwin]

Do it regularly without any problem.

Aly1 - did it once many years ago and ended up ripping the cable out of the plug - thankfully at the van and not the bollard!! Re-wired and all was well - but talk about embarrassing!!!

 

[suavecarve]

Never even thought about not doing it and never had a problem

 

[chaser]

No problems here, at a guess I'd say your charger was already gone.

Tip of the day: Always walk round the van 1 last time before moving

 

[glenn2926]

As above and I always put the reel for the EHU lead in front of the pedals just in case .

 

[peterc10]

Not had that problem with either my previous Adria or my present Hymer. Mind you once or twice my wife had to get quite agitated to stop me before I moved the length of the lead!

 

[WillH]

Have done this dozens of times, no problems at all.

 

[kevenh]

Why the two different situations?
Is it down to the motorhome's built in charger type?
On EHU, our motorhome uses a 12v switchmode PSU as the charger and only tops up the Habitat battery.

edit: PSU rated to supply 13.8V

I always route the cable up over the driver side mirror as my m/h's EHU inlet socket is on the driver's side.
Never had a prob when starting with EHU connected and live.

There is no theoretical reason why it should cause a problem. I have done it by accident with no issues. However I wouldn't do it intentionally. Possible voltage surges if your protection systems are not up to scratch I guess. But just a guess.

 

[Reusables]

Interesting, but this is something I always do.

EHU is on a few days before we go away..fridge on .

Then when we're ready to go I start the engine and leave it ticking over for five minutes whilst I disconnect the hook up and check lockers.

Never had a problem.
