I think I've got few issues with my LE and I'm wondering if someone can give me a few pointers where to start, what to look at, etc, or tell me it's normal and don't worry about it. Please forgive me, I'm new to pinball maintenance so I may not be using correct terminology for parts or areas of the pf. Also, I'm sorry for the long post... Just trying to provide as much info.
- The upper flipper seems slow, both extending and retracting. I press the button and the lower activates, and about a tenth to a quarter second later the upper activates. Same when I release the button. I can activate just the lower without activating the upper if I slowly or lightly press the button. With the pf up, I can both see and hear the contacts in the button making and breaking at different times. This makes me believe it's a button/switch alignment issue. Admittedly, I have not run a solenoid test from the menu yet. I'll check the resistance of the solenoids too. The flipper/button counter audit is somewhere in the 32k range, 44k for the right. EDIT: the solenoids are dirty. Wiped a ton of black dust/grime off the shaft and linkage with a dry lint free rag and it seems to be reacting better. As for the switch, yeah it's supposed to do that, at least that's how they are built.
- My shooter lane doesn't seem straight... About 60%-70% of the time on a full/hard plunge the ball will bounce off of something and either roll back towards the arcade or if it's far enough roll back through the pop bumpers or the lane just above it. Sometimes it will just bounce around the upper part of the lane and slow down to a crawl and barely make it to the upper flipper. This bounce happens around when it reaches the metal inverse "V" ramp to the upper playfield. It's not the post that comes up if I don't hold the left flipper. It is level left to right and probably closer to 5*-6* rather than 6.5* inclination on the pf. Could my shooter rod spring or tip be worn out? Maybe the gate for the skill shot is sticking or catching the ball? Not sure what other parts to check for alignment in that area. EDIT: the shooter rod was very dirty and I cleaned it up. Also cleaned the skill shot gate. It only happens now maybe 1 in every 4 plunges. However, on an auto plunge it happens about as frequent if not more, so it must be something in the lane.
- My spinning disc seems weak. I've cleaned it (yes, read through the threads about cleaning, replacement, etc) and that may have restored some spin, but the majority of the time the ball just seems to "fall" out of the area. Doing a motor test does make it spin at full speed and does both directions. It's loud and vibrates during the test, but barely noticeable during play. Also checked the resistors under the pf and those do not seem loose, broken, or damaged. My next step is checking they are within spec. I'm not looking for crazy spin, but what I have just seems too weak compared to what people have said theirs does. EDIT: This appears to be a non-issue. The disc spins and occasionally whips the ball out. But I'm chalking this up to a 10 year old disc rubber that was probably never cleaned and therefore lost some of it's grip.
