I am running 2 lanes of scalextric sport and yesterday noticed while my son and I were running our cars round the track there were some funny occurences. It started out that if one of us crashed the other would get a sudden power boost and quite often crash as well due to the jump in speed.

Then i noticed that if one of us stopped our car and the other kept going that the one who was going solo had very little power until there were 2 cars going again. And then when there were 2 cars going again the power would be huge and we would barely have to be touching the trigger to go high speeds.

I am not aware of anything i have changed in the track to cause this.

I have used 2 extra power bases around the track (not connected to a wall wart) as substitutes for half straights but this isn't new.

I have 2 wall warts connected to the one power base and have it set acordingly to the setting ~x2

I haven't tested the voltage yet but wonder if anyone has any suggestions as to the problems i am experiencing

Cheers

I think your intuition is right. Ditch the two extra powerbases and then see. If you have them set to x1 then you are shorting between the power supplies

The scaly power boards are a wierd set up in that it converts the AC power from your wall wart into a really crappy DC. Have you mounted all the other power boards in the "same direction"? What I mean is lets take the simple case that you mount two power track pieces one after the other. You can do this in two ways. Both the power track pieces have the "power" plugs to the outside and they are side by side. Or you can mount one so that it has the power plug to the outside and the other to the inside. I suspect that doing this will confuse the shite out of the rectifier circuit inside the power board.

So make sure you connect them up the same way. Either both pointing out or both pointing in. This should fix the problem but its not guarenteed 100%. The alternative is to ditch the extra power boards and just run one.

hi
the golden rule is never to have 2 powerbases in one layout unless you disconnect some of the wiring in one of them..

Much safer and simpler to purchase a half straight and insert that where the second pb is...

Have you done this so each driver can sit at opposite sides of the layout.??? Using the prefered one powerbase approach you could purchase or make up some throttle extension cables so each driver has access to more of the track for marshalling purposes...

Hi,
I have experiance the same when I was using 1 power base with one power supply.
The boost is a result to less "resistsnce" on power drag when one of the cars deslot. For seconds all the power is dedicated to the motor of one car, and accelerates until you adjast the hand controler. The best idea is to stick to one power base,as bigbird suggested, and use two power wall warts, with the appropriate seting #x2 on the power base. With this setup, each car will have its own power supply and will not be affected by the other.
Try it.

Thanks for your help gents, I have 2 wall warts in the 1 power board but 1 of the power board is running in the opposite direction so I will turn that around and hopefully that fixes the issue, already spent way too much on track, borders and cars, and havely just started on scenery
