Why does my auxiliary fuse keep blowing?

The three causes from the most common to the least common are: An electrical device has failed. If a wiper motor or power lock solenoid have fried and melted on the inside, it might start drawing too much power in an attempt to keep working. This overloads the circuit causing a short and a blown fuse.

Why does my 12V socket not work?

When a cigarette lighter socket stops working or seems to malfunction, there are a few things that can go wrong: The cigarette lighter socket is blown – This just means that there’s no power getting to the socket at all. The fuse could be blown, or there could be another problem with the wiring.

Can a vacuum cleaner blow a 10A fuse?

In practical terms, NO. However I doubt very much if your vac would blow either a 10A or 15A fuse. Fuses (unlike MCB’s) typically tolerate a short-term overload up to double their rated current. The 10amp fuse had blown, now replaced. Not on EHU at the moment so did not check the vacuum cleaner in the 12v outlet whilst on EHU.

Can a 12V vacuum cleaner be used in a caravan?

I took the12v car vacuum cleaner and plugged it into one of the two 12v accessory sockets within the caravan. The caravan was on EHU at the time, caravan is a Bailey Pegasus GT65 Ancona.
