Title: Universal Ulta, The latest project. Post by: Slam on May 20, 2013, 11:36:20 PM Hi all, I just picked this one up today,01-97 Universal Super Jackpot sys-94033 game-95033 I gave it the once over & everything looks pretty good accept for the main board. It has some old sloppy repairs that were further damaged by another battery meltdown lol. I have looked around abit & have not been able to find a replacement board,(board: 94014-main4) any suggestions?

Title: Re: Universal Ulta, The latest project. Post by: Slam on May 21, 2013, 04:16:08 PM Several of the tracers are trashed, in addition to the one someone previously jumped. I will probably end up fixing it, just wanted to see if there were any boards floating around out there first. Here is a pic of the old repairs.
Title: Re: Universal Ulta, The latest project. Post by: jbshocks on May 21, 2013, 05:40:42 PM That would have been a pretty extensive repair for a hack. I would bet it works or can be made to work. Do the 4 LEDs light up at all?
Title: Re: Universal Ulta, The latest project. Post by: Slam on May 21, 2013, 06:14:52 PM led's on board not lit, reel lights out, not showing any life on front display where error codes should be. do have power to all lights, bv, coin comparitor, etc. hum coming from speakers.

You have a fair amount of green slime around the battery and the edge connector. This needs to be cleaned up. If it were me I would label and remove all socketed chips and then run it through the dishwasher (skip dry cycle) then rinse with 90+% isopropyl alcohol. Any green sticking around scrub off the edge connector and around the chips. Use tooth brush or small brass brush but be certain that no brass strands sticking around. If any legs on the ICs are tarnished gently clean them. I use 400 grit sand paper. Once completely dry test it. Remember the alcohol is highly flammable so it must be completely dry. The alcohol can get trapped behind a chip.
You could attempt to spot clean the board but be certain that the edge connector is clean. Title: Re: Universal Ulta, The latest project. Post by: jbshocks on May 21, 2013, 07:56:17 PM also did you try the ram clear ?
Title: Re: Universal Ulta, The latest project. Post by: Slam on May 21, 2013, 08:16:24 PM Since I took the photo, I cleaned the board with non-chlorinated brake cleaner & a tooth brush, That got 90% of the crud off. I do have a couple tracers to repair, will get that done tonight, then install & try a ram clear. I'll keep you posted.
Title: Re: Universal Ulta, The latest project. Post by: uniman on May 21, 2013, 08:53:20 PM Wow, someone really repaired that board, or tried to. Definitely check that battery for voltage. Ultras need the battery to function.
Without led's on board flashing left to right your dead in the water. Title: Re: Universal Ulta, The latest project. Post by: Slam on May 21, 2013, 10:59:08 PM Well... got the board all cleaned up, repaired tracers, installed new batt, tried a ram clear. still no change, leds not lit & still have a hum from speakers. What do you think i should try next?
Title: Re: Universal Ulta, The latest project. Post by: jbshocks on May 21, 2013, 11:35:34 PM I take it that you verified the traces from the battery? Have you checked the fuses? Are you sure the board is seating properly? Sometimes these boards seem seated and are not. If all that checks out I would test voltage on the test taps. Use clamp on test leads, things are so tight that you could easily short otherwise. See link below. Uniman may have another suggestion. He is the guru on these.

Post by: Slam on May 24, 2013, 10:29:13 AM Update: Thank you for all the pointers, I got her up & running. Overlooked another tracer, repairing that one did the trick :3-
If anyone does happen upon a board for this unit, pls let me know. Would like to have a backup, just in case. Thank you again for the help. Title: Re: Universal Ulta, The latest project. Post by: jbshocks on May 24, 2013, 10:30:41 AM Glad to hear it
