The colours in your post are not the same as most controllers.
The Professor Motor web site says the Avant Slot Hammer M is wired White (Power), 2 = Red (Brake), 3 = Black (Track) - which is the same as Parma etc.

The standard wiring on a positive wired circuit using 3 pin 2 amp sockets is
Track to N
Power supply + to L
Common to N

Are you sure the descriptions in your post are correct?

Sorry I've added to the confusion by making a mistake in my earlier post
What I should have said is

The standard wiring on a positive wired circuit using 3 pin 2 amp sockets is
Track to N
Power supply + to L
Common to E

The manual supplied does indicate red and black are the opposite way round to what it says on the Professor Motor web site.

Now if we could have a post from somebody who has successfully wired up one of those controllers to a positive wired track telling us which way round actually works.............

I agree with Rich about wiring.
Every make of controller I've come across with red white and black wires has them wired like Rich's diagram.
The problem appears to be the manual supplied to Mr V says the Hammer doesn't follow those colour code

The Professor Motor web site says the Avant Slot Hammer M is "Dual polarity switchable to adapt to any analog track", so if that's correct it should work on either home set or British club wiring as long as the switch is in the right place.

Hi aerodynamic
Sorry to say it's not like that

The "Positive wiring" talked about on this thread is all about which way the electric current goes through the controller.
It's important because some electronic controllers will be damaged if connected to the wrong polarity.
It is not about whether the right or left hand tape in the direction of travel is positive

(The car will either go forward or backwards depending on if the right or left hand tape in the direction of travel is positive.)

Most club tracks are positive wired, but the occasional one isn't.
Might just be worth checking if where you race is wired the normal way round.

Hi Tom
You are right, resistor based controllers work for either track polarity.

The latest Slot.it SCP-2 controller is available with a Universal Home / Club Racing cartridge. The earlier SCP01b and SCP01c Sloit it cartridges and all their high current cartridge only work for one track polarity.

The one in the close up (2nd photo) which says COMMON + (negative wiring) is negative wiring. (rather confusingly, Common positive and negative wiring means the same thing)
I cannot tell which polarity the one in the third photo is. If it says COMMON - or positive wiring on it then it's definitely positive wiring. (Common negative and posative wiring means the same thing)
The standard for those 3 pin plugs (4th photo) is positive wiring. So assuming the track has been wired to the standard it's posative
Hope that's some help, but I guess it's not the complete answer you'd like.

You might get replies from some other Slot.it users if you started a thread with Slot.it controller in the title. Threads titled "Avant slot Hammer M controller wiring." will most likely be read by those interested in Avant controllers.
