So I am picking up a HD cockpit hopefully this evening. Currently not working. I was able to test the PS and it's dead. I didn't have time to check the supply power from the transformer. The monitor turns on, screen is dim but uniformly lit. This said, the monitor is chattering (not too loud).

So, who's really familiar with HD on the forum? I'm sure I'll need a bit of help. I'm going to start with testing everything and go from there.

Once everything is working, I will be doing a complete restore. I will document everything with photos....

Will post a photo once I get it.
 
Start with the ps then report back. Check to see if its getting AC and making +5v.

I have compact upright. Yours is medium rez. You will need a cap kit for the monitor and probably have to rejuv the tube. But worry about that later.
 
Thanks, my thoughts exactly. I am not going to be able to sleep tonight as I just got it home and unloaded. Ill post several photos first thing on Saturday. I'm planning to start testing the PS's on Saturday and get it working before I do any restoration.

In any case, everything is there, no structural damage. In overall good condition, no cracks in the fiberglass and the seat is in outstanding shape. Seat magnet may be non functional, per the past owner, but I can get to that later. A lot more to come, normally I don't document my restores, just post at the end. This round I will post as I go with lots of photos...

I would be willing to assist. Send me a PM if you want and I can try to help.
 
I just checked the supply power to the power supply, it's ok.
Check the +5 on the PS, nothing, power supply is shot
Also, one of the fuses are out on a 20v line from the transformer, will replace.

Question: I have an extra power supply that I can put in, but I don't want to assume it is wired correctly as is.

Here is what I have:

three brown wires
one brown and white
three red wires
one red and white

Can someone jump in confirm placement on the switcher? Also, do any of them need to go on the FG (Frame Ground)?
 
Here's my thread:

http://www.dragonslairfans.com/smfor/index.php?topic=3095.0

Regretfully most of the pictures are gone because of MobileMe shutting down....

At the moment the sound has died again and the biggest problem is the steering wheel.

Got a new pot for it now though....but I can only work on it in good weather because I have to roll it out of my game room to be able to do anything....
 
Here are pics of mine...the red and white and brown and white are kinda hard to make out, but just follow the wire in the pic.

when you remove the wires, wie the PS off and see what it says. Any PS will do as long s you connect them to the right lugs. I think its just +5v and ground.

I think if its blowing the fuse, it might have a problem with the feedback motor/pcb.

Got it, thanks guys. I'll go out in the garage after work and hook it up. My extra supply is untested, however it's putting out +5 without a load, so I will have to see what it does once I hook it up. Will report back tonight.
 
sweet. I hope you get her up and running easily just be replacing the supply.

Do yourself a favor and replace all the fuses if they look good or not.
THeres been more than one member(including myself) who chased all kinds of weird issues on these games due to fuses that looked good but were blown, or fuses that were dropping voltage across themselves.

If the monitor ends up needing work, if its a wells k8000 get the chassis rebuilt and KEEP IT.. its the only frickin monitor that works without picking up steering motor "noise"
 
So here are some photos. I'll post more in a few minutes...

So here where things are at after some initial testing...

I replaced the 3A 250V fuse on the bottom right of the fuse holder. It looks like this fuse / circuit sends transformer power to the APU.

I hooked up to my spare p/s , made sure everything was connected. I started it up and the same fuse above was blown. It also sent the power supply into shut down mode. Obviously there is a short somewhere.

I suspected the APU so I disconnected the red and brown wires that come from the power switcher that sends +5 power to the APU board. I replaced the blown fuse and I left every thing else hooked up, basically ONLY isolating the switching +5 power from going to the ACU. This said, the APU is still getting some power from the transformer itself.

Started it up, fuse did not blow, switcher did not shut down, here is what I have:

Main PCB boards are up: all lights on, EXCEPT for CR1, CR2 on the large board closest to the Seat, should be good, as they are the test LED's I think...

Main PCB: CR3 on the center board is not on, area for concern?

Motor AMP: LED ON

Shifter board: NO LED. The current PTC .9A, 50V fuse is blown (see photo, what is the best place to get one of this rating)? I also tested the incoming power to the Shifter board, no power to the Shifter board. I assume that is because the APU is not being fully powered as I removed the +5 in from the switcher to the APU? Perhaps the fuse was blown as there is an issue with the APU?

SGB Board: LED ON

I did one more thing. I hooked up the +5 power to the APU from the switcher, but before I turned things back on, I unhooked ALL cables going into the APU (except for +5 power from the switcher) and started things up. No issues. I then hooked up one cable at a time back to the APU. All of them don't cause a shut down except for the top middle connector and the bottom left connector.

Oh, I also unhooked the shifter board and the motor amp connectors, to make sure those were not causing a fault/short. With those unhooked, I still could not hook up either connector mentioned above to the APU without causing a shut down. Not sure what other PCB's may be hidden that could be causing a fault?

In the end, do I have a bad APU or what else should I look at isolating from the APU to see if something else is causing a short?

Also, I need to get a fuse for the shifter board, ideas on what I can do there?

Can't thank you guys enough for all your help. My plans are to restore this to as near new condition AFTER I get it functional.

hmm. wtf is melted there?? is that on the apu or the shifter board?

WIth thw apu connector disconnected what works and what doesent?? like do you have video? can you drive?

I will have to get in my attic and see what i have left.

Back when i was trying to hunt down my phantom coin lights issue i thinki bought another apu board and of course cameup with the same result so let me check and see if i still have it. I have some cockpit and some upright parts but to be honest at this point i cant remember what was what. I need to dig back into my old posts and make sure ive actually tested this apu thats the way i remember but im not getting any younger hehe.

If thats the shifter fuse thats all blown and melted there id check the wiring from the shifter board to the shifter assy. THe top cover of the shifter comes off with 4 bolts. Make sure the wires arent rubbing/shorting in there.

Thanks Cadillacman! LOL, I thought the same thing. It was just the PTC fuse that burnt to a crisp on the Shifter board. I replaced the fuse and the connector, also traced down a shorted cap on the shifter board, I also replaced all the caps while I was at it on the shifter board with new ones that I had on hand. Have not tested the Shifter board yet as I'm not getting power to the board. I'll pull the cover off the shifter tomorrow to check for shorts.

No video, monitor is shot until a full rebuild. Game seems like it plays blind, tough to tell though as it's hard to get through the set up screens without a monitor. At one point last night I was able to turn the key and start the motor...

When you say with the APU connector disconnected, what connector are you referring to? Right now, everything is hooked up EXCEPT for the +5 (red/brown) power wires from the switcher to the APU. All boards come on, except CR3 light is not on, on the center board, not sure if that's an issue. All other boards LED's are on, EXCEPT for the shifter board, no power at the connectors.

If I hook up the +5 to the APU, it shuts off the switcher and blows the 3amp fuse below the transformer that seems to power the small board mounted by the clutch springs.

I've tried unplugging all hardware to try and isolate, but to not avail...seems like an issue with the APU?

Let me know what your thoughts are, APU? If so, let me know if you have a working one, you'd be a life saver...or if anyone else does on here. Not to sure if my Steering board is ok, may need one of them as well...we'll see.

Also, after my initial post today, I found two shorted caps on the APU, replaced all with new ones on hand, no change though. Let me know and I can dig in from there...

Here are some, I do have one wire not hooked up (purple), which I believe goes to the seat release light/button.

ranchdrsn --- soooo, guess what? The white/orange plug was in the spot where the red/brown should go. Switched it around and no more short! THANK YOU!

So, the Shifter board is still off, but it's getting power now. I think there is a short in the shifter that I need to track down, but I don't have the correct security bits to take it apart. Where is the best place to get them? There is a differnt, smaller size needed for the seat assembly as well. They are like allen wrenches with holes in the center.

Once I figure the issue with the shifter out, hopefully I can power up the shifter board.

Since I don't have a monitor I put the game through the blind tests via the jumpers on the main PCB, all tests passed. That's a good start.

Also, I found the dip switches were all off but I believe they should be all on for game operation. Am I wrong?

When I add credits, I can hear it coin up. Coin counter works. Coin lights are dead, not tested yet. Is there a way that I can get the to a game so I can see if it plays blind? The other day I was able to "start" the motor, but can't seem to get to that spot again without having a monitor. From memory, I think there is some test/set ups that you have to do first before you can get to play the game? At this point I can add credits, but no lights on the abort or the seat adjust. Steering wheel moves a bit, motor seems to be operational.

Again, thanks ranchdrsn! Making progress....

Also, monitor pulled out, it's a K5515.
 
Here are a few photos from today's progress...
