Just finished the restoration of my Back to the Future and decided to add a custom topper. I will try and show all I did. I apologize for some of the pictures as the camera doesn't take real good pictures in low light so some of the pictures are a little fuzzy.

I started with a 1:15 scale battery operated car that had some lights and sounds. They are all over eBay.

I started by gutting the car and taking all the electronics out. The car has headlights, Brake lights, Fin lights, instrument panel lights, Flux Capacitor lights and exterior time travel strip lights. I took all the light circuit boards out and removed the clear plastic time circuit lights on the exterior and removed the blue LEDs Here are the original light circuit boards.

I ordered 12 volt prewired 5mm LEDs. I took the old LEDs out of the boards and then I drilled holes where the lights were. I then put the wires of the new LEDs through the holes and glued the LED to the board. By doing this, I was able to use the original boards to place the lights exactly where they were before. Here is one of the light boards with the new LEDs installed.

Here is a pic of the entire car rewired with new LEDs.

Then I took a piece of flat metal and bent it to shape and painted it black. Here is a pic of the bracket attached to the bottom of the car.

Here is a pic of assembling the car. FUN FUN.

For the wiring, I wired two different circuits. I wanted the headlights, brake lights, interior lights and fin lights to be illuminated when the machine is on. Then the blue exterior time travel lights are on another circuit. I took all the positive wires of each LED in each circuit and tied them together. I then took the negative wires of each LED in each circuit and tied them together. I then hooked each of those bundles and attached them to a single wire to go outside the car for the connector.
Black- Negative for the continuous illumination circuit.
White- Positive for the continuous illumination circuit.
Brown- Negative for the Blue exterior time travel circuit.
Blue- Positive for the Blue exterior time travel circuit.

Here is the car with the plug attached. The wires are kept behind the bracket so they cannot be seen.car plug.jpg

Here are the test pics of each of the lights.

Now that everything checked out the car was attached to the backbox.

I installed a switching power supply to run the undercab lighting and the lighted flipper buttons. For the continuous circuit I ran wires down to the front of the cabinet and attached to the 12 volt power. Here is the power supply.

I decided to run the Blue time travel lights to the Release flasher so using alligator clips I attached it to the flasher that is in the backbox. I used alligator clips so I can experiment with different sources for the blue flash. Playing several games I am happy with this selection but I may try some others at some point in time.

Once all the wiring was done, I re-installed the backbox vent screen.

Here is a pic of the car installed and illuminated. I will add a video in a bit.

I am thrilled with how the topper looks and operates during the game,

Here is a video

Thanks.
I am real happy with how it looks and flows with the game.

They make versions for all three of the movies as well.

It is a BTTF II car but the wheels don't rotate. I agree and I am gonna take it down and cut them out and re-mount them. The problem is that they are not finished on the other side so I might have to do some painting of the rims and I may have to cut the tires to get the right look. I wanted to get everything working first before I spent the time on the wheels. I can take it off in about 30 seconds so I will post pictures after I change the wheels.

It appears they made at least 3 different cars for BTTF II that come in a similar box. I remember seeing the flying wheels one time so I ordered one for II and when I got it the wheels didn't fold. I just thought I saw it wrong but evidently not. I don't like the look of the ones with folding where's as they look too much like a toy. I think modifying the one I have will end up with a better look. Mine also does not have Mr Fusion either which struck me as odd since it was supposed to be from the second movie. I don't care though. I'm happy with it.

I actually had a graphic artist working on that in exchange for some artwork I gave him. It never panned out. I had hoped to have that as a surprise during my restoration but it didn't work out.

I took the topper down and did the flying wheel mod.

I took the axles and tires out and made a 90 degree bend to the axle. In order to get the right position I drilled new holes in the wheel well and cut the rims and tires so the wheels would slide in further.

Front wheel well

Rear wheel well. The upper hole was the one used for a better placement.

I didn't like the shiny axle so I sanded it to take the shine off. I debated on painting it black but decided to use it this way. In order to hold the wheels in place, I used side rail tape. This will allow me to take them off easily if I decided to paint them.

Finished and installed.

Lol. I take full responsibility for my actions.

Got it off eBay. Do a search for 1:15 Delorean and there are several different kind to choose from.

Wow. That's detailed.

If you want them all on all the time then that would seem to work. They might be a little dimmer than normal but it might not be noticible. Worth a shot. Let me know how it works for you.

Hello everyone. Got some cool news (or at least I think its cool). lol
I am starting a YouTube channel that will be mostly dedicated to pinball restoration. Many of you have followed my restoration threads and I appreciate all the feedback. It's fun so I thought I would expand a little bit. I will still have my restore threads but I hope to add videos that compliment and show what and how I do things instead of just pictures.
I have a few videos up and would appreciate any comments. Keep in mind that I am just starting this so I will get better. Please be gentle.
