AL320

Hello Guys,

Just saw this in the manual:



- J4 molex caimano mlx 94213 - 2014 (connettore “F” usato per la connessione al

Frigorifero; da non usare per il montaggio del Frigo AES)

- contatto N.4 Æ Negativo

- contatto N.3 Æ Positivo +12 (Potenza)

- contatto N.2 Æ Positivo (+12) (Bassa Potenza)

- contatto N.1 Æ Ingresso per eventuale dispositivi acustici



Why AES fridge should not be connected to the AL320?

Because AES fridge use more current with other model.

Hello Simone



my AES fridge power line is connected to cell battery . The fridge ground line is connected to AL320 on F4 and the signal line (12v low power for fridge electronics) is connected to AL320 on F2 (fridge light). Is this setup correct? If not, how an AES fridge should be correctly connected to AL320?



Im asking this because i found out the fridge works on 12v with engine off, which might indicate a D+ connection problem (not receiving alternator OFF signal) and im trying to solve the issue by trial and error approach (its a second-hand motorhome i dont known for sure what the previous owner did regarding electric wiring and connections)



Many thanks

The connections are correct. Normally the fridge not work without engine. Check if you have a problem on D+ signal. Also check if you have 12V on fridge connector (d+ contact) with engine ON. If you have 12V only engine ON probably your fridge have a problem.

Hello SimoneR

tks for yr reply.

I will check D+ connection as i think alternator signal is not reaching the fridge.



Stay safe

Hello

You have check d+ signal on red connector? If you haven't it, the problem is on cable from engine to AL320
