Calling all MURVI owners. (Habitation Heating) HELP WITH FUSES!

[L' Hobo]

I have a 2007/8 Murvi Morello with Eberspacher HYDRONIC D 5 W SC 12v heating system on a Fiat Ducato X250 LWB Chassis that has a Eberspacher Blower, Part No. E6520 in the wardrobe.

The Eberspacher main unit under the floor of the van, appears to be working fine, heating the water etc BUT the Blower unit, although blowing well on 240v but will not blow on 12v (This has been VERY slow to start on 12v, ever since I bought it in 2019 and has now stopped completely!)


I have the blower unit out and on my workbench at the moment, and with my VERY little knowledge of electrics, everything appears okay including the 12v blower fan that worked well when connected direct to a battery.

Is there a FUSE or RELAY in the Eberspacher system that I haven't found and, IF so, could anyone tell me where to find it please?

Many thanks and I'm sorry I cannot put up pictures but my phone doesn't want to, even my man at Tesco Mobile cannot manage it!

Hi. I have a Murvi but I can’t help. Are you a member of the Murvi owners forum? If not I can post this over on that forum to see if anyone can help.

I have been studying the, not very helpful, handbook and looking at YouTube which seems to show everything except a MURVI but it appears I need to find a fuse holder containing 3fuses.
I will dismantle more of the wardrobe panelling surrounding the Spaghetti Junction wiring tomorrow. Wish me luck!

A weak connection to motor is enough for it not to start up....... Found that in an old Carver system.

It runs okay on EHU which is most annoying as it seems to be the same 12v fan.

It could be so many things including thermostat etc.?

It keep me from chasing women!

EHU supplying the full 12.8V the fan wants and that overcomes the loose wire?

I connected up and tried that yesterday just incase the draw on startup was too great.
No success!
