Wiring Problem

[conan7772]

I've got a current drain in the boot, and I'm pretty sure the capacitor is draining my battery along with my boot light which doesn't turn off as we found out today.

Anyway, the capacitor, and both amps are in the boot and currently wired as shown.

My head unit has a faulty trigger out so it's bypassed, just looped it off accessory in.

Trigger wire goes to amp 1, then loops to amp2, then loops again to the cap.

They all share a common ground bolt connection along with the battery.

Power supply first goes to the capacitor as it has a nice fat terminal that accommodates 3 x 8mm wires, and star wires out to the amps.

A horrible pop sometimes comes out of the speakers when the stereo is switched on.

I guess I need to fit a 40amp relay somewhere in the wiring sequence shown, and possibly have them looping in the correct order.

Any help, appreciated.

cheers

Is it necessary to hook the trigger to the capacitor? Maybe that is what is causing the problems. Might be ghetto but perhaps you can set up switches to the trigger line until you can get a better and working head unit.

Yeah, the capacitor does require a trigger wire from accessory, otherwise it won't turn on.

Weird though, current still draws even though it's off.

A relay should sort it out, but I'm not sure where it goes in the sequence

if the caps drawing current it may have developed an interal short , a relay between the batt and the cap will switch it out but your limiting the current flow cause it goes throught the relay, with the little terminals and the like, your gona create other issues. I'd disconnect the cap 4 now. First I'd yank that boot light and see how the battery goes.

the poping in the speakers, is cause there's a slight delay in the amps remoteline, that allows the amps IN the headunit to startup before the External amps are trigered,

2 options there

1 , take the remote line of the accesorys (back of the deck), and put a switch in . that way youl basicly turn on the key then the switch or

2, betta option, instead of a swtch as in option1 , put a 12V delay circuit in. I've seen a few on FleeBay, but if ya know anyone good with electronics they could whip ya something up. only needs around 1 second delay

or a new deck I supose
