Sega Indy 500 4 seats
« on: July 28, 2020, 08:24:03 am »
I will use this thread to post what it takes to get 4 games fixed up, and playable.

All four seats were playable when I picked them up. Two of them had no force feedback. Two of them have force feedback that needs to be adjusted.

There are some marquee lights out. One had a non working monitor, but the seller had a working one included that they just never got around to installing.

The seat latch is busted on a couple of them so those seats don't lock in place.

When I got the second pair of seats home, seat 4 displayed all of the overlay text and 2d graphics, but none of the 3d game graphics.

Seat 2 has scratchy audio. I replaced the pot with a known good one and no change.

So those are the main issues.

      I started by swapping out the bad monitor for the good one. That was easy enough. Everything worked great except I was getting a loud static discharge at random. Before I put the bezel back together I am going to pull the monitor and make sure everything is connected the way it should be. (Over the course of a few days the problem seems to have solved itself)

      My standard procedure for weird problems is to pull the socketed chips, clean them and reseat them. Well the ROM board on this bastard has 19 or 20 rather large socketed chips.
So I just swapped the ROM boards between seat 3 and 4. If the problem followed the board that would narrow things down. My laziness was rewarded when I fired up the cabs and the problem disappeared.

     My next job is to physically align all of the cabinets and put the topper on seat 3 and 4. I will post a bunch of pics when I feel like it.

Everything is in place now.

Next job is to fix the static discharge problem on monitor 2.

So I pulled monitor 2. It has a loud intermittent static discharge. That is my guess anyways. Every minute or so there is a loud snap.

My diagnostic skills consist of looking for obvious visual damage, and texting bperkins01.

There was a spot where a diode was supposed to be. Instead there were 2 twisted together and it was all scorchy in that spot. Luckily I have 4 other chassis to compare to. 3 active and one spare.

The other chassis just had a single diode in that place. I desoldered the offending diode and grabbed a replacement from my spare chassis.

I put everything back together and I ran it for 30 minutes with no loud snap. Replacing the diode or just pulling the chassis and reseating everything fixed the problem. I like it when it is easy.

Time to crack open a few victory beers.

Next step will be to fix the wonky connector on monitor 3. The jumper for Medium Res mode keeps shutting down the signal and the screen goes black. When you jiggle that connector the picture comes back.

Tomorrow I will pull the chassis and reflow the pins on the header. If that doesn't work I will remove the header and the connector and replace them with molex.

Forum member thatpurplestuff came through big time.

He worked up excellent image files for the seat numbers.

He didn't ask for any compensation.

I am going to put together a swag package for him.

Who should I get to print the seat decals?

I don't have a clue man, sorry.  I wish you'd make some progress though..... I've got a root canal scheduled for Monday and I'm running out of stuff to distract me from the pain in the meantime.  Basically I want you to dance for my amusement.  ;)

Well either I messed up something fixing the header or the monitor took a ---steaming pile of meadow muffin--- at the same time I put it back together. Gee. I wonder which is more likely. No big deal. I am going to pull the whole monitor and get it fixed up. In the meantime I have a tri mode monitor I can throw in there.  I had to order some stupid  monitor connectors to match the odd ones they used for this game. They are on the way.
It's okay. Three seats are working. I raced my brother yesterday. The game is fun.

Local print shops could probably handle the job. Other than that, if he is taking custom work, Szabo’s arcade stuff is really good quality.  Ask Opt how his X-Men came out and I think he’ll give you the thumbs up.

Ask and ye shall receive.

Seat 4 had a broken start switch. It functioned, but looked like crap.



I was going to try to match one up from the usual places, but I found an entire panel for sale on eBay for a reasonable price. Now I have spares of the other buttons.



Much better.

Seat 3 is the one with the wonky monitor so it doesn't get played much. The up down shifter only shifts up. The seller was upfront about it.

Let's see if we can solve the mystery together kids.



Alright kids. Count the wires on the left coming from the shifter. 1...2...3...4. Four wires. Very good.

Now count the wires coming from the wiring harness.  1...2. Two wires. What the ---fudgesicle--- kids?

The ground wires on the left go to one ground wire on the right.

Wire number 3 is hiding.



Naughty wire. There you are.

I am not sure why this post turned into a kids show. It might be the alcohol consumption.

My buddy kept getting beat by his 10 year old son over the weekend. I figured out that there is a game setting that keeps all of the human players close to the lead human player.

His son is going to be so pissed that he is all of the sudden not good at the game anymore.

I am finally going to pull the monitor from seat three and work on it this weekend. Bperkins01 is going to help me with some long distance tech support.

PRO TIP: Always try to make friends with people smarter than you.

There you go Howard. A little bit of progress.

When you own as many machines as I do, you learn how to prioritize.

I have a full time job that unfortunately cuts into my arcade repair time.

Nice work man.  I like those easy fixes myself.   ;D  Yeah something I didn't realize until I started building my racing rig was how stupidly expensive the sega racing buttons can get... well for what they are anyway.  Buying a spare panel was the smart move.
