Electric help needed

[Dave Lawson]

So installed b2b charger (victron) amt12-2 but the ignition live piggy back keeps the engine running after I take the keys out?

 

[Niknak]

Can you send the wiring pic over that you’ve done also I would not use a ignition live I’d go to the bcm for engine run signal instead

[Niknak]

What are all the feeds going to the “in”

 

[Niknak]

You have no control wire linked looks like that you might be back feeding the fuse box from the in feed

 

[Dave Lawson]

Feed in is: starter battery, ignition live and amt trickle.
Feed out is: leisure battery, amt trickle.
Negative is: vehicle chassis and amt trickle.

Why have you got ignition going to the in that is your problem

 

[Niknak]

Your putting a permanent up a ignition wire when you switch off it will feed it

@Dave Lawson - I have not ignition live connected on mine. No operating problems. I spoke to Albemarle and told them my set up, they replied I did not to connect a ignition live.

 

[Niknak]

For best result should have a engine run signal going to the two way green connector no ignition should be in the in as effectively you are feeding the ignition system permanently

 

[Pete C]

So you have joined ignition live to the starter battery positive ?

It will keep running because of this.

What @Niknak said. Your ignition live should not be connected to the starter battery input. It should connect to the H terminal on the green connector.

Cheers @Deaky i could not remember off top of my head which terminal so didn’t say didn’t want to get shot down lol

 

[Dave Lawson]

Attach ignition live to here then? (Yellow circle)

 

[Niknak]

Yep but I would not use ignition use the engine run feed

Take a look here for the connection and operating mode options you have with the Victron B2B charger: https://www.t6forum.com/threads/val...tery-how-we-done-it.22182/page-11#post-332484

Any links on how to get a feed from bcm? And best way to do that H connection?

 

[Niknak]

@Deaky he will know the bcm pin, this is used to trigger the Victron

On a T6. Pin 3 in the black plug on the BCM will give +12v when the engine is running. It will need coding. Module 09 Byte 17 Bit 04 Battery Seperating Relay active. Set this to 1
