Thread: Quick one on rear AUX wiring - no power

Disconnect the positive from the front of the vehicle (on the Aux battery) before connecting back together.

Sparks aren’t cool

Cheers Tombie, sounds easy enough then was a bit hesitant to dive in since the ABG box still had its green light on.

Is there a more robust style of connector, it didn't take much to dislodge the attached cables? Not planning on keeping the jack in there but it would be a useful space to throw a small bag or container in for spares. Maybe save on disconnecting the battery etc if removing said spares bag pulled it out of the connector again.

Looks like soft solder on the tips of the wires used under screw compression. Not done anymore. Soft solder will creep and become loose and cause a hot connection ( or simply fall out as shown in the photo) Same goes for soldering before crimping. Use twisted bare strands only under screws or crimp aglets to the wires first if you're anal. Matti

That connector block has screw terminals so just unscrew , push the wires back in and tighten.

Right on the money.

That is the output of the ABG-25, and the bare wires are coming from the power sockets, not the battery. So just reconnect the RED wire first and then the BLACK.

No need to disconnect the battery, and if you can't do it now, it will be quite safe until you get around to doing it.

I only recommended undoing power feed first as I’ve seen some people arc the screw driver.

Better safe than sorry when commenting was my thought!

Cheers drivesafe that's easy and I hope no sparks :-) thanks for the advice, appreciate it! If in doubt, Tombie's advice on disconnecting the positive from the aux additional step.

Also watched a couple of videos' on Youtube since posting and the importance of a good physical and electrical connection was highlighted.

As matti4556 said it's better to have twisted bare strands so could cut and strip the soldered cable ends off and join again. I don't have any specific crimp or stripping tools for this yet but maybe a good investment for very basic tasks in the future if not on the pending trip.

Because of the very problem you are having, a number of years back, I changed from those Screw Blocks to Yellow Crimp Terminals.

These are not only more secure, they make this a Plug-N-Play setup.

It would be quicker and easier for you if you got some MALE and FEMALE Yellow crimp terminals and replaced both Screw Blocks.
