Revolution Ricos T6.1 2021 plate - electrical faults

[Pidsley]

Thanks for reading. You'll see if you look at my post history that I've had various electrical issues since new. Latest one is baffling me. Revolution have gone bust, so have no way of getting wiring diagrams or advice from them direct.

The leisure battery (under the driver seat) is fully charged and tested.
There is no power going to the leisure equipment from the battery (i.e. fridge, lights etc.)
There is no recharge power reaching the battery from the running engine. Main engine starter battery is recharging perfectly.
There is no recharge power reaching the battery from the 240v mains when the van plugged into the house supply. (240v is working and all leisure systems working (apart form battery charging), when connected to 240v supply.

Any advise would be really helpful.

I attached some photos of the wiring and modules attached to the leisure battery. Could someone also help me identify what these are? Thank you so much.

There are two red cables going to the positive batt. terminal. The empty fuse here, does have a blue fuse installed. I removed it to check the contacts. made no difference when i puched the fuse back in,







What is the VW AG box. The yellow fuse also has a black fuse behind it, both fuses seems Ok to me,

The webasto diesel heater is also now not working working.

The module on the left is a control unit for your headlights. The one on the right could possibly be for your webasto. if there is no current flowing in either way then check the earth connection from your leisure battery to the body. Maybe post a pic

On our 2021 Ricos the fuses to the right of the headlamp module are for the heater as Deaky says.

Whilst Revolution has gone some of the team have set up on their own in Peterborough as Escape Campers and Andy Burgess is still active in the Revolution facebook owners group so you could try there.

Our original Numax leisure battery lasted just over a year and Martin at Wambam Campervan replaced the battery with a lithium set up as well as some other bits and pieces for us. It wasn't the first Revolution camper he'd seen so he has some familiarity with their wiring arrangements. I don't think he's too far away from you if you have no luck getting to the bottom of things.

If none of your chargers are working then how is your battery fully charged?

How are you checking that each individual charger is working or not and the battery is fully charged - I don't disbelieve you but if we know the exact tests done it might give some more clues.

In particular how are the 12v leisure systems being supplied when your 240v EHU is connected?

Right now it sounds most likely the wiring was routed through one common fuse to the leisure battery terminal that has failed, but there are a few things that don't fit with that thought.

Thanks again for the replies. The problem was sorted (I thought) with a main common fuse replacement. However, the problem remains as follows:
. The EHU is not charging the Leisure battery. (not voltage increase at all when plugged in and switched on), all known fuses checked. Mains 240v sockets within van do work.
. The engine does charge the Leisure battery when running. The Sterling battery to battery charger works, but does run quite hot.

I have a PowerPart consumer unit, All fuses and trips are working. All Fuses on the bottom RH panel also work. (apart form the V Battery 20amp one, which doesn't seem to do anything, if fuse in or out.

Question: where is the EHU 240v to 24v battery charger likely to be found. Is it inside the powerpart board or a separate piece of inline kit somewhere.

Hi thanks for the replies.

Basically, I fully recharged the leisure battery using a nocos standalone charger.

I have a Rico's van too, although I've since replaced all the original electrics kit bar the Power part unit, and also noticed there was no charge to the leisure battery on EHU. Maybe that unit doesn't facilitate it? I'll keep an eye on this thread and hopefully someone with more knowledge on this stuff will be able to help.

There is a power supply in these units, it's not really a charger as such it's just a PSU running at nominal traditional alternator voltage of 13.8v - a traditional leisure battery will charge of that just not as well as off a proper multistage charger.

Unfortunately the original manufacturer of these units supplies trade and isn't very open about them so there is not as much information online compared to say Victron equipment.

This advert does show the looms involved with the various feeds labelled. And It has a copy of the installation instructions, which are not very clear about the behaviour. It looks like the power supply is fed from the second 6amp 240v breaker.

Unfortunately to see what's going on you may have to start tracing wires.

Do you get a voltage reading from the leisure battery through the control panel.

The video here PowerPart PDU Operation shows a green LED visible through the vents in the unit when the charger in the unit is switched on (it is turned off and on again just over a minute into the video). Could be worth checking to see if yours is behaving the same way.
