Hey everyone, so I am facing with a problem that I just can not figure it out. I bought my 1980’ T25 like a year ago and having this problem now. Well, the installation of my auxiliary battery and like the whole electrical system of my van seems a big mass to me (I have not a lot of knowledge) but seemingly and stuff I learned from other places it’s just feels not right and can not figure it out what can happen. I have a fiamma water pump installed under my kitchen (I bought the van like this) and it was working fine from the beginning, then just one day an other stopped working. I was thinking maybe its the pump itself so I replaced it but when I was touching and unscrewing cables, it apparently started working again and honestly was happy about it but also me a bad vibe But yesterday it was also gone. So have no water pump anymore and don’t want to guessing around. Would like to re-do the whole installation but lack of time and money at the moment not an option (maybe after summer). Now I would like to go and enjoy the van a couple of weekends but don’t know what can I do how can I start my search for a fuse, bad cable etc as I mentioned when I bought the van it had this same installation and got no problem until now. I asked a friend for a brand new water pump just to try, I connected the same I had the fiamma one, still not working. Faucet seems ok as its just working as a switch I understand. Tested voltage and batteries are good, electricity arrives from the battery to the pump. Will attach some pictures maybe it can help detect a problem or some suggestion or just an explanation why and how this all connected. Also pump before was working even I was camping without keys inside. And I have a usb charger connected to the auxiliary battery and sometimes only sometimes when I cllick my faucet the light of the usb charger go out :? Reealy strange. So its like grounding, electric shortcuts? Do not have an idea and dont know where to start. Well at the moment don’t want to take apart and redo installation at the moment, maybe could save myself and enjoy my van till end of summer?

Show a photo of the led panel on your kitchen.

If the left column has 2 reds at the bottom then make sure one of those 4 leds is on but not the very bottom red one.
If the bottom one of the 4 is red then you have the very early led panel that disables the sink pump if it thinks the water tank is completely empty.
The bottom red of the the 4 leds says "empty, don't run pump".

Thank you, my water tank is full but I am not sure my leds working properly anyway, but maybe can be my level indicator tricks my faucet ? Can just disconnect this from the side of my water tank?

Also, I think if I remember well in other occasions when had no water at all, could run the pump with no issues ( obviously not running till its broke) at least could hear it’s sound and working and as I said just tried with a brand new pump and same issue.. touching tap, click sound, no water pump sound…
