Quoted from Scorch:
Wondering if you guys can help me out. During the initial test on startup, I get a diverter error. When I go through the supercharger test, the diverter opens and closes with no problem. But when playing the diverter just stays closed all the time (except for maybe 1 in 20 games it will open up and the supercharger works). Otherwise it just bypasses the supercharger.
I checked the opto on the "on ramp"in the switch test and it seems to work fine... but during play if I block the opto, nothing happens.
Would love to have anyone's ideas on what might be wrong.... one question I have though is at what point is the diverter supposed to be open? Does it open only when supercharger is lit, or does it open when supercharger is lit and a ball passes the opto?
To begin with, when "open" the diverter moves to the left so that the route of the ball is around the supercharger loop. The diverter will only "open" when one of the two SC ramp lights are on and a ball passes the opto (not before). When running L2 firmware (I can't speak for the others), at the beginning of the game the SC light will be on, so any ball making it past the ramp opto will trip the gate and route the ball around the SC, so should be easy to test. Otherwise, the ball is diverted to the left around the hairpin turn and down the wire frame to the left flipper. Also, if you hit a weak shot up the SC ramp when one of the lights is on past the opto but not high enough to hit the first magnet, it will trip the gate open when ascending and then trip it closed when descending and passing the opto on the way down (at least it's my perception that the opto being triggered as the ball descends is what closes the diverter).
Now then, if you are saying that during game play with one of the two SC ramp lights on that when a ball passes the opto that the gate does not open, then I am confused how it works perfectly in test mode and not in game play (sorry, I know that doesn't help you). Honestly, in that situation, it sounds like an opto to me. Can you take the glass off, start a game, get the SC ramp light lit, and then block the opto to see if it trips the gate (just pass something by it, as you don't have to hold it there)? Quickly pass something by a second time and I think the diverter should close.
The solenoid test will open/close the diverter (solenoid #01) repeatedly, so what happens when you do this? Additionally, you should try the switch test for opto functionality. The opto at the base of the SC ramp that trips the diverter is #84 (called different things in manual and on DMD, but #84 is correct). Put in test mode on this switch number, then pass something between the optos (your finger, a business card, etc.)to see if it consistently opens and closes (closed is default, open when path between optos is blocked). Personally, I have replaced all 5 pairs of SC optos on mine (ramp entrance, 3 magnets, and one above tunnel hole), as they were the source of constant problems (all have worked perfectly since I replaced them months ago).
If you find the solenoid to be erratic, I would suggest the following as it relates to the optos:
- If stuck open, make sure nothing is out of alignment, as there needs to be a line of site between the two
- Clean both the transmitter and receiver with cotton swab and alcohol
- Double check wiring and make sure there are no shorts, loose wires, bad solders, etc.
- Buy 5 new opto pairs and replace them all ASAP (will take some soldering skills)

- Current brackets are broken, screw hole is stripped, or you just want new ones: http://www.pinballlife.com/index.php?p=product&id=167
Hope this helps, and please report back.
