I'm aware the circuit goes via the Electrobloc, what I don't understand is you say the fridge has power when switched to 12 volt and the engine is running but no charge to leisure batteries?Thanks. Ammeter above habitation door. Charge from engine goes via Electroblok. Fridge charging. Leisure battery not.
Have you tried measuring the voltage at the leisure batteries with engine running, if so does it increase with engine running or not?
Thanks for reply. Voltage access leisure batteries does not increase when engine is running. This is a mistery to me as the fridge works in mobile use and some 14.4v is measured at the Electroblock. As a further check on a cuircuit breakdown do you know which port on the Electroblock sends out the charge voltage for the leisure batteries? Many thanks in anticipation.I'm aware the circuit goes via the Electrobloc, what I don't understand is you say the fridge has power when switched to 12 volt and the engine is running but no charge to leisure batteries?
That suggests the D+ signal is being received by the Electrobloc and unless there is a break in the circuit to the leisure batteries they should be receiving a charge.

It was a 29. I have changed motorhomes recently.Which model number is your Electrobloc.?
ELB 99. ThanksWhich model number is your Electrobloc.?
Thanks my Electroblock is ELB 99. This could be wired differentlyWhen I had an EBL the charge arrived from the engine battery through a big wire on the back and went on to the leisure battery by another big wire on the back. When the D+ signal was received by the EBL an internal relay linked the two. If the two are not at the same voltage when the engine is running then either the D+ signal is suspect or the relay may have stopped working.

Here is a link to the 99 manualThanks my Electroblock is ELB 99. This could be wired differently
Thanks for update. It is beginning to look that the Electroblock is faulty cf p5 faults in ELB99 manual. I would just like to make absolutely sure that this is the case before ordering a replacement.Here is a link to the 99 manual
I don't think there are any significant differences in respect of the battery connections or internal relay. The 29 is the replacement for the 99 which I believe they have now dropped.
He never did reply to me, I thought he may have left as I saw he was praised. Luckily Martin at A And N sorted me outUdo Lang at Schaudt was very helpful when I wanted some advice 2 years back. He replies to emails in English.

Perhaps he has, what a shame.He never did reply to me, I thought he may have left as I saw he was praised.

Thanks for help. Problem was a faulty 50A fuse next to starter battery. Solved.I would also check that you are getting the same voltage at the EBL end of the engine battery connection. If you are and the D+ is also live at the EBL then I would be suspicious that the separator relay within the EBL has failed.
