    Hi everyone, newbie lacking knowledge.

    I have my sons hot wheels race track, what started as what I thought was going to be an easy job has me scratching my head? In the US this hot wheels track comes as a wall plug unit, for overseas its battery operated. I thought wiring a 6v power adator would be straight forward but to my surprise the unit has two seperate 3v motors requiring 4 D size batteries, two D batteries per motor, can I adapt (split) a 6v power adaptor to run both motors or am I better using a 3v adaptor with higher amps?

    Maybe any better suggestions?

    Thanks all

    That would simplify things for you IF you can find that adapter. Another approach would be to find a 5 or 6V supply - easier to find, in my opinion - and use an LM317 adjustable voltage regulator to knock the voltage down to 3V.
