Just was thinking,if you do you own d.i y say piggy back fuse and all done spot on with fuses etc.

Say for another circuit for whatever, how are you covered say if something does go wrong.

Also how safe is it ( piggy back / lower fuse rate / another inline fuse /insulation tape ) etc.

The voltage output is the same for all fuse locations, the fuse rating is matched to the demands of the circuits attached so as long as a matching fuse is used everything is fine.

In regards to insurance technically you should inform them that electrical modifications have been made, they may request a letter of certification from an auto electrician stating that the installation is sound.

Don't think i will contact them but was just thinking about it as i have 2 new piggy back set ups.

Dash cam and tracker,i do go over the top on protection as use lower fuses etc.

As you state as long as the right fuse is used,do you mean the right fuse for the item you put in or lower.

As long as the fuse matches the amp rating of the device or closely as possible (7.5A for a 6A device for example) you will be fine.

You don't want to go lower or else you'll be swapping fuses all the time.

I see now,so far no problems with the 2amp in the dash cam or constant live for tracker.

I found a spare fuse hole on the fuse box so constant live is through that one.

Just say the wire pops off and earth out will it just blow the fuse as it's joined,piggy back to device.

Odds are very low how i have done it but never had it happen.

As long as the fuse does it's job then you're fine.

Cheers for the help.

Just thought i would ask.

No worries.

All done again and wired in a better way from fuse box.

Do 99% of people do these themselves.

Most people with any DIY ability would, others would get someone else to do it.

What you've done will be no differnt to a pro doing it, aslong as you've fused it correctly it will be fine,

Yes mate it's all done ' over the top' piggy back 2 amp and 2 amp inline fuse and wires all joined
by bullet connectors and double joiner connector and bit of tape round them.
And cable tied up.......yes i'm always over the top on stuff i can't see

I wish they did a piggyback fuse that was inline. so rather than a fuse coming out, and the fuses going in at a right angle to the rest of the board, I wish they had one you could just put into the fuse circuit and have the fuse pointing the same direction as the rest.

Never the less, the circuit you have done will be sound, as long as you have got the positive and negative the right way around.

How do you mean,positive and neg the right way round,you mean how the fuse fits in.

Would it not work if was wrong way and i thought as long as the fuse makes a circuit it's fine and it all works.

When a regular fuse is located in the box the power goes in one pin and out the other (bridges the terminals).

A piggyback only uses one terminal for the top fuse as the other pin goes straight to the attached wire.

If you have the piggyback the wrong way round the power will go straight to the wire bypassing the top fuse therefore leaving that circuit unprotected.

How would i check this as i have an inline fuse in the circuit as well but also a spade type.

Thank god for people who knowes as i did't think about this,is this only how the piggy back fits into fuse box

or is it the fuse as well as i will check the fuses and put them the same way as in the fuse box.

Also its in a spare fuse slot on the fuse box

Put the piggyback in without a fuse in the top slot and attach something to the wire (like a voltmeter) and touch to earth (If an ignition live fuse then turn ignition on, if permanent live then no ignition needed of course ;) )

If there is a voltage showing then turn the piggyback through 180 degrees and test again.

I only have a test lamp,what i will do is pull the fuse out,there is no way to do it with out taking it all apart.

It will takes ages as all taped up and stuff and hidden away with cable ties.

All i can see is the top of the fuse piggy back.

So the fuse workes both ways then just the piggy back,i'm till confused.

If it was working the other way from fuse box won't the earth i have connected be live and not work.

Sorry for being thick lol

If you take the fuse out and whatever you are using won't start it's fine, otherwise it's going to need turning if no fuse and it works still.

It's basically a switch the fuse closes the circuit bur I'd something goes wrong it's the emergency stop. But if your prodding the main power supply with a knife and licking the mains supply before the switch occurs.

You read my mind lol

Was just going to say and do that,was going to take fuse out and see it tracker works with out fuse.

If it works it's wrong way round,will try that now.

Come to think of it, it charges my tracker up as always on 100% so must be going through fuse to

make the circuit.

Anyway fuse out of piggy pack and will see if it drops from 100% over night.(still got inline fuse) so

still safe.

O.k all done.

Taken fuse out and left all night and was on 100% charge and now on 80% so must be going through fuse.

Putting it back to normal now as it's in the right way. :) if this is the case.

When i put fuse in and it goes back to 100% it's all fine.

Nickname easy :-)

LOL :)

Just for info purposes which way round is the fuse tap fitted?

Here is the picture of it fitted,the one with the clear cable tie is the spare fuse hole and 24/7 live for tracker.

Other is ignition for dash cam,both fitted with another inline fuse on the live wire ( mini spade type )

looks like the wire pointing towards the driver? or is it pointing to the road in front of the car?
