I am changing a couple of things on a guitar I just bought - Universal 12 Exel
I am putting a G# to F# change on the 6th string and want to do a split - It has the stops for all 12 strings in the endplate (which I have screwed out all the way and it is not touching) but when I move the lever that pulls the lower finger it also tries to pull the raise finger with it at the end of the pull - I can't see what is holding it unless the changer will not allow that long of a pull - I have the pull rod in the end of the finger for the longest pull possible - also, does anyone know what size tuning wrench it takes for the nylon nuts - Is it 1/8" or metric??

| If it has a raise helper spring on that string remove it. Also try changing the changer hole that the rod is in and make sure that your 6th string is a .020 plain- not wound. |

| Using a .022 string may help. If not, I'd try reducing the tension on the lower-return spring - by adjusting it (if you have a tension adjustment screw), or by installing a lighter spring. |

I've got a couple of lowers on my Fessenden U12 that take the changer to the limit (including a wound 6th full step lower). I think--I've got to double check--that I've got a .24 SS on 6....I found stainless gives me more pitch change but that opens a whole other subject. In this case it's stainless vs. nickel from juststrings.com. Going from one maker to another blurs the issue and makes this a meaningless distinction.
Anyway--on each of my full step lowers I had the same problem of the pitch starting to rise before it reached the full lower and yes, the solution was in fine tuning the return springs. |

Zoom in on this photo concentrating on the changer.
The "Split Screws" are located just to the right of the pickup. There is a row of 12. In reading your post, I perceive you are talking about something different, since you used the term "end plate". But then maybe not.
On all other PSG's that use split screws, they are located to the right of the changer. But due to the way the Excel changer works, Mitsuo had to locate them to the left of the changer.
Assuming you meant these screws, then I agree with Donny. Use a .022p. A .022w usually will not make it.
If you are using a .022p, then I agree with the "lower" return spring being too tight. These screws are located at the BOTTOM of the changer fingers in the end plate.
The raise "helper" springs are located at the TOP of the changer fingers. On some models these are hard to find. On the new models as pictured, they are in plain sight and easily reachable.
Be carefull of the following:
1. When adjusting the "return" screws. The rule of thumb is; to make them JUST tight enough to always return a string after a string is lowered; but not so tight as to cause the problem you are having.
You will have no problem in loosening the "raise" helper springs, But you WILL have a problem if you get them too tight. Most PSG's do not have them. And they can be more problem than good if they are too tight.
I have an Excel S-12 Superb and I have always lowered my 6th and 10th strings from G# to F# (and "split" them) with no problem.
If none of the above works, try this: Manually try to lower the string, by reaching under the guitar and push on the "lower" finger. See if it will do it this way. If so, then I agree with Jim Palenscar. Try using a higher hole on the bellcrank OR a lower hole on the changer finger, (or both) for your G# lower on this pull rod.
Note: "Higher" means further down from the bottom of the guitar, when the guitar is in its upright position. "Lower" means closer to the body of the guitar or closer to the changer axle.
This has confused more than one I garontee ya! 
If none of the above helps, you may need to contact Mitsuo @ Excel in Japan.
May Jesus guide you to the solution dear person,

It did have a wound 20 - I replaced it with a Plain - I never realized how much difference that made - I think that might do it - Got my biggest suprise when I mashed the "B" pedal and the G# to A jumped up over a full step!!!
I will have to play with it a little later - Back to flood detail for the rest of the day here in Rochester, Iowa (along the Cedar River)
Does anyone know the wrench size for the nylon tuners?
Thanx......Ron
