Hello all.

Just a little help, how many times can I splice a 12v wire? I need to run two LED's and two gauges from the 12v that plugs into the radio, do I run the risk of overloading the circuit by splicing the 12v wire? Or do I need to run a seperate wire for each guage from the battery?

Also, is this the same case with earths?

Everything seems to be working fine just don't want to "overload" the circuit.

Sorry for the newb questions I'm not that up on car electrics.

thanks.

LEDs draw next to no current, but the fewer times you splice it the better.

Make sure that the total current draw on that feed does not exceed its fuse's rating, or it'll keep popping - you won't solve it by putting in a bigger fuse, as that'll just let more current through before it melts, which can be disastrous.

Depending on what you're actually adding to the wiring, you might be better off taking a feed from the battery (with a suitable fuse as close to the battery as possible), with some way of switching the power.

How come you've chosen to pillage the radio's wiring?

 

First thing that came to my mind with it being on the ignition.

Everything seems to work fine...

 

A fuse is there to protect the wiring, replace the wire your splicing with some bigger AWG wire, and if theres room, use a proper distribution block. You can even use fused distribution blocks, how many gauges you planning to run ?

 

Just these two - there is a little problem of room behind the radio/dash.....

 

I thought this was all a little too easy

 

Yeah no problem at all with just a couple of gauges and LED's, they'll draw next to no current

 

Brilliant - Thanks Rich.

 

OE fuel pumps work on wire that aint really much thicker.. and they can draw a Load of current.... if the wire melts,, then you got it wrong lol
