Relayed Fuse Block

xJWhip804x · Jan 14, 2020

Wiring up new fairing for bike. 10GA from battery to connector, 10GA to amp, 14GA everywhere else. Idea is for relay to provide power to fuse block once headlight comes on. Fuse block tells amp to turn on. Is my plan solid? Quick connects are for if I need to remove fairing I can just unplug it. Thanks in advance.

Looks like it might work.
Might be an idea to run the amplifier off the fuse block too, as then you dont need to worry about any parasitic drain it will have.

Thanks. So is it ok to run 10GA to and from the 40A relay?

Presumably you mean 10 awg.
I'm in the UK so work in swg.
That said this table gives you ratings for 10 awg:
