IVECO Daily 6 - Euro 6 - Smart alternator feed for Orion TR - 2.5v?

Hi guys,

I'm new user of Victron products but not I’m new to modern vehicle electronics or renewables. For a bit of background I am currently upgrading our Iveco Daily with a Cerbo GX, Lynx Distribution, Multiplus 12/1200/50, MPPT 100/50 and a Orion-TR Smart 12/12- 30 (plus other bits and bobs of course - BMV, Battery protect, isolators and fuses etc). Currently the system with be supporting an SLA battery but LiFePO4 or two are planned sometime in the future.

I know there are a ton of posts out there along the same lines but I have a query with the dedicated alternator signal wire for the Orion TR. Our MY2018 Daily have 210ps EURO VI engine with factory upgraded 210amp Smart Alternator (not start stop).

I have read through a number of the smart alternator DC-DC charger posts on this forum and others but nothing specific to the

To cut to the chase: -

Iveco provide a body connector which amongst other outputs provides a alternator status wire. On this wire I was expecting and ~12v when engine running/alternator charging and )v when alternator/vehicle battery is not changing.

I have not hooked up the Orion TR yet but as per installation and operation manual I ideally want to connect the status wire to the Orion TR H-pin and have it charge the leisure battery when alternator status wire is greater than 3v.

So with that in mind I have measured the following on the alternator status wire: -

0v – Engine off
2.55v – Engine running (note 14v+ measured across battery during engine running indicating alternator is charging)

I don’t have an oscilloscope but I don’t believe it’s a CAN signal

I need to do further testing as it’s entirely possible that ~2.5v is output when the alternator is not charging and 12v is output when the alternator/vehicle battery is charging.

Does anyone on board have any experience with eth Iveco Daily Body Connector (post 2018)?

Thanks.

I believe it's covered in the Iveco body build manual, not sure of the name.

But if you don't get a clear answer, take a feed from the radio switched connection, and set the start delay in the Orion to a reasonable period. You might get an answer on the Iveco Tapatalk forum, but it's not getting many answers most of the time.

have you tried a pull up resistor? the data does show that it should go to +12, and from the table I'd expect that to also be able to source up to half an amp. Have you tried any of the other signals to see if they function as expected?

Best I know is that you should see +12V, as the manual and @Mike Dorsett say. I had something similar on my Daily IV, for reverse engaged. There is enough there to trigger a reversing camera, but I got a silly voltage reading on my meter.

I'd wire it temporarily and see what happens.
