flichobay Posted June 22, 2016 Share Posted June 22, 2016 HELP! My Chausson 08 has a Thetford auto fridge which has stopped working on the 12V with engine running. There appears to be no power to the connections at the back of the fridge with the engine running. The fuses in the 12V distribution box in the rear are all good. Has anyone any ideas about where to look next? The base vehicle is a Fiat Ducato. Any help or ideas very gratefully received. Many thanks Chris.

MrWoo Posted June 22, 2016 Share Posted June 22, 2016 I had the same problem with my Ducato based Bessacar. There is a fuse box in the engine compartment on the bulkhead above the battery containing 3 fuses, the 20 amp had blown. Link to comment Share on other sites More sharing options...
Robbo Posted June 22, 2016 Share Posted June 22, 2016 MrWoo - 2016-06-22 11:03 AM I had the same problem with my Ducato based Bessacar. There is a fuse box in the engine compartment on the bulkhead above the battery containing 3 fuses, the 20 amp had blown. If it's an 08 Ducato then the battery will be under the cab floor with the fuses. If the fuses are OK then it might be a fault in the system that turns the 12 volt on when the engine is started. When the engine is started the D+ terminal on the alternator sends a signal to a relay which then opens the 12 volt circuit to the fridge. It the fuses are OK suggest you first check the 12 volt at the back of the fridge for loose wires or corroded terminals. Link to comment Share on other sites More sharing options...
sshortcircuit Posted June 22, 2016 Share Posted June 22, 2016 You may well find the fuses and relays behind a large black plastic cover in the middle of the engine bay held on with 4 nuts. Please feed back how you get on. Link to comment Share on other sites More sharing options...
Dave74863 Posted June 23, 2016 Share Posted June 23, 2016 I have a Ducato 2004 model there is also an inline fuse in a lead that comes off the alternator ( can't remember the rating this was the cause of mt fridge not working, Link to comment Share on other sites More sharing options...
