1. my  3a  backpack fuse went last night - could i find another one!?? no way. I stuck a 5a in - it works, more power, better if anything, but will a I break something

2. just had delivery of my flojet pump + eco-flow. trying to wire it up via cigarette lighter plug in car.
the fuse inside the lighter plug is only 5a, but the fuse that came with the pump is 15a - what effect will this have?

Can I change the fuse in the lighter socket to a 15a and forget the seperate one ?

the fuse that came witht the flojet is in a closed loop. do I just clip this (piggyback style) onto the red wire going to the battery / lighter socket. - if I am in fact gonna use it.

if I do buy a leisure batery - i still don't know what to do with the loop thingy !!?

Please help.
ex - electricians welcome!

if you're going to have a leisure battery, get a split charger. I paid £10for my ring one and it comes with loads of thick wire

its simple, they are rated that way for a reason. If you want to put larger fuses in its up to you but the wiring could overheat and cause a fire. The inline fuse should be left simply to protect the unit from a short.

use the correct fuses for everything, they are there to burn out before anything else..

your pack pack could well have a loose wire somewhere and this could cause the fuse to blow.

Make sure you don't spill water into the back of your backpack, If this happens and water touches the positive and negative terminals of your battery, it can cause a high current to flow, this will blow the fuse.

Go to Halfords and get the right size fuse and only ever use a higher rated one if you know the cause of it blowing in the first place and you have rectified the fault, also only ever use the higher rated one as an emergency only, and replace it as soon as possible.

ok.

what bout the flojet fuse then ?

I'm not 100% sure of the current consumption on the flojet.

You talk of the plug and socket in your post, if the fuse is in the plug that is being wired to the pump then you can do away with the fuse completly and just use the pump fuse,  however if its in the socket then the fuse is in there to protect the socket and cannot be up graded for a higher one.

Plug it in and run it for a few minutes, keep hold of the plug and see if it gets hot, if it gets hot then there could be a problem with the fuse blowing, if it just gets warm then there shouldn't be a problem. HTH

A flojet pump is 9amps I believe so you could get away with a 10 amp fuse instead of the 15 amp one.
