Weird electrical failure.....

[stef46]

Hello from France. I am recommissioning my Jimmy for another roadtrip and I have a strange electrical problem. The lights and electrical equipment don't work when only on the auxiliary batteries but when I start the van everything works. My battery terminals are clean, both batteries are charged and the fuses behind the seat are good. Do you have any ideas?

Tu pouvrais faire trois tests et afficher la tension à partir de l'affichage central ici :
- Pas d'alimentation exterieure et pas de moteur en marche
- moteur en marche tournant seul
- alimentation exterieure L
'erreur peut être à plusieurs endroits...


Bonne Chance, Lincoln

Good evening, I looked at my electrical connections this afternoon. Engine off nothing works. Engine on with my auxiliary batteries connected everything works. The engine on and the batteries disconnected all also works.
However, I noticed that the auxiliary batteries are not charging. I have no power coming to the terminals. So I removed the driver's seat. The relay engages well when the engine is turned on and snaps when it is turned off. I have 14.2v at the output of the relay. Is there a fuse before the batteries? Where is it?
Thank you for your help.

You really are the best. The fuse has blown. I bought a 100 amp fuse. I will make a part to install it properly. Thank you

Great! Be aware of the reason for the blown fuse… please check properly!

This is the new part with a new 100 amp fuse

Last year i have a problem with the 12v westfalia charger. I did a temporary repair and it didn't hold....
