Need new batteries? Going from 12V to 18V or 6V to 12V? Wiring Questions?
By sparky

I have a Step 2 Mighty Mac truck. I bought 2 6 volt batteries and put them in series. There is no wiring diagram. There is a red and black wire that I connected to the battery. The truck runs forward in fast speed. There is also an orange and gray wire. There is no reverse or slow speed. I believe that is because the orange and gray are not hooked to power. If anyone has one of these trucks or knows the hookup, please let me know. Thanks, Sparky.

Ground wires, perhaps?

I suspect one 6v should be connected to the red and black and the other should be connected to the orange and grey. That's just an educated guess, I'm not familiar with that particular vehicle. Make sure you hook up a fuse in case I'm wrong :?

Make sure you also have some hair gel handy for that cool spiked hair look! :lol:

I appreciate the responses. The orange wire is fused and the gray would be the negative wire. This is a 12volt system. I have tried hooking up each set to a six volt battery and nothing happens. Keep those suggestions coming. Thank you all, Sparky.

Very true, a picture may help as well - I'm no wiring guy, so just a suggestion.
