Myself, and the other mods have been very nice and lenient with the rules. We have been deleting threads, and giving out warnings. Some members didn't get the clue and re-posted over and over... Now ANY member buying or selling in this section will be banned... No IF's AND's or BUT's.

These are the rules. Read them. Live by them.

1) Absolutely NO flaming! "Flaming" is an outright attack on a member. ALL questions are encouraged to be asked here, no matter how basic. Members with over 30 posts will be subject to a ONE WEEK ban if caught flaming in this forum (and yes, moderators can read deleted posts). Members with under 30 posts will be subject to a ONE DAY ban.

2) Use appropriate language. Racial or sexual slurs will not be tolerated. A ban will be issued at the discretion of the cb7tuner.com staff.

3) No items may be sold in the Beginner forums. Any "for sale" threads will be deleted.

4) Temporarily banned members will be PERMANTLY banned if they are found posting on another account.

The rules can and will be added to. Any updates will be marked in the title.

        Classic sign of a leaking cap.
        I'd say it's rubbish, Even if it's not - It won't be long before it is.

        If at first you don't succeed, Try again. Don't give up too easily, persistance pays off in the end.

            It is most definitely bad. I had two bad ones that looked just like that. Cap is short for capacitor, which is the large cylindrical object that has leaked all over the board.
            There are no black and white suspension answers!!!!!!!!!!!

              hanks for he info another bad thing i just found out from Honda is that, that TCU is only compatible with 90 CB's that are Auto of course and only LX/DX not EX's

              and some more crazy stuff is that i just put back hat TCU in my CB and its shifting fine again i really think its just this cold weather cuz i kept it in th house for a good hour

                Hahaha..

                That puppy is toast.. Those two resistors sitting side by side, the one on the left is black and gray..it should be the same as the one on the right.

                Not as bad as one of my Ebay finds though.

                  ^ they also have a bad smell too. if you have a leak in the floor board, if you cant track it down, wrap the tcu with a bag. lol , i seen my pop do that before and it worked.

                  A man that keeps looking back can't see whats in front of him.

                    The interesting thing is?

                    Both of the boards pictured above have the exact same numbers printed on them as does my burnt up board. Look at the lower right, it's:

                    SPU6098-4263PI
                    EAT X4J/A-B

                    The TCU I bought to replace mine had a different number and a different manufacturer... and the board is laid out differently.

                    The only reason I'm saying anything is that if it was just a long run of bad boards it might be easier to avoid getting another one if anyone knows what to look out for.

                    So far I'm just guessing, but I've kinda been watching and it looks like the bad boards are all the same manufacturer...

                    But I'm sure someone else would have figured it out a long time ago if that were the case..

                        if you clean it with some rubbing alcohol and see that the circuity is still in tack then yes it can be repaired...just from the looks of that...that one is gone..get another from the junkyard and call it a day

                          I tried it with mine. I bought all new caps and some resistors from Mouser, cleaned the board up and replaced the components.

                          It lasted about 2 hours before the main IC got hot enough to start cooking the board underneath it.

                          Parts + shipping from Mouser was $11, used TCU + shipping from Ebay was only $18.
