Quoted from dtrimberger:I'm a little late to the Stern Star Trek (pro) ownership game but better late then never. But I need the Pinside crews help.
I bought a Pro that had seen some routed time. At some point the R gate (52) was removed, I didn't realize this until I started playing it, it really isn't an obvious game play loss. I found the empty molex and it is working (plugging it into the Vengeance (53) fires the vengeance). So now I have to track a R gate assembly down.
The good people at Pinballlife are going to ask stern for one but they note that this is hit or miss. In the event they don't find one I guess I have a couple options. First does anyone have a Stern Star Trek they are parting out that I can buy the gate from? Second the R gate appears to be a fairly generic stern rail gate, whats the consensus here about using the R gate from Spiderman or BKSOR (they appear to be exactly the same, BKSOR has a extra removable bracket)?
Incidentally the coil on the L gate (51) is out as well. Again the power to the gate is live but the coil appears to be out, insulation fried to the copper. The L gate is more rare because of its bracket. In the spirit of the fixes noted in the discussion after the post above I have a new coil for it coming so I think that will work.
Thanks everyone, I'm waaaayyyy new at this but the pinball bug has invigorated some Mech Engineering I haven't done in 23 years. Only wishing I had paid more attention to my EE classes...[quoted image][quoted image][quoted image]
Posting an update on my Stern Star Trek Pro for posterity so that if someone comes across some of the issues I've had in the future they can find it on a search. Side note, I find Pinside to be a bit like that old Dane Cook joke that if you search A:F6 someone will have posted about it on here.
I was able to get the L gate functioning by replacing the coil with the Stern Relay Coil 090-5060-01-ND (non-diode) from Pinballlife. Disassembling the gate is easy after dremeling the rebound pin to remove it. Then just solder in the new coil and you're gtg. If you ever have to replace the L gate and don't want to solder don't toss the L gate bracket as that's what makes it unique for star trek. Otherwise I think you could use any stern L gate and just replace the brackets.
I highly recommend the QuadHands helping hands from Amazon for soldering. Nice heavy base if you need it for your workbench but also the arms are magnetic and long so you can attach them to your pin with the playfield up to solder under the pin.
Pinballlife was able to get the R gate for me for $55 (don't hold them to that price forever). I do actually think that any R gate from other machines could be used for the Star Trek R gate. It has a standard rail mount bracket which looking through build manuals seems to be pretty standard for orbit gates for several machines, some of them just have different extra brackets attached but the rail mount is the standard starting point. In fact whoever provides stern with gates industrially engineered the gates to be reversible by just flipping the gate, rebound pin and clevis pin. The holes are already manufactured in the metal brackets so you can always go L to R or R to L if needed. The gate from PBL does come with wiring so don't waste several days trying to find a local source for Molex connectors and tinned 18 g wiring (marine boat equipment store if you're wondering) like I did.
The Vengeance kickback wasn't working but interesting I would test with the Ohmmeter and get an occasional connection. Turns out the wire was broken as it passed through the soldering base so when I would put pressure to test with the meter I would sometimes get a tone. Easy to solder this, just hard to get to because of some poor playfield plastic protector screw locations at the L ramp.
I had one RBG which had a non-functioning blue LED, easy to solder and cheap part to replace.
I used a spherical adhesive bumper pad, the kind you see on the back of framed pictures, at the lowest pop bumper to prevent ball hangups. Haven't had a hangup since and it's really the best option I could think of in comparison to some of the other fixes on the pop bumper fix forum.
I highly recommend the velcro fix for the warp ramp (I still suck at it) and also recommend changing the right 2 enterprise inserts with the Red Stern Spike LED from Cointaker. They really bring those two inserts up to the same level as the others and make combo shots more visible.
I'm also several mods in. Shaker motor and blue flipper button LEDs from Pinballlife, flipper covers and coin door cover from Cointaker, sling covers from Pinbits, I printed Aurich's rule cards, have some Cliffys coming, and have a bird of prey and enterprise coming. That's almost it for awhile as the wife is getting suspicious with all the packages coming to the house.
Finally, I vote for Red LEDs for the Vengeance flasher. When that flasher starts pulsing red before the multiball I know shits about to go down.
