Rookie Mistake. 

I got all lower pays working on multiple coins by adding tension to pay disc.   It wasnt returning all the way to zero before starting next coin pay.   
  I never took apart paydisc assembly so I just add one rev to spring by taking off at post and giving full rev. 
It did pull wipers to zero before next coin payout started counting. 
Buuuttt, on 200 coin pay the wipers could not go around twice.   Reached a point that tension was to much and ran out hopper.   
Tomorrow i am going to dissassemble properly and clean and lube.

Been there and done that before myself..    When you take the hopper apart, make sure the 100 tooth gear shaft is not too tight.. I have seen them swell up or the bushing shrinks. I did have to file one lightly before to get it to work correctly.. You want your spring tension as light as possible. I figure if it returns to zero on a 2 coin payout it's perfect.. I'm not 100% sure if the payout wiper boards suppose to have the contact grease or oil used on it, but I usually put a very light film on it to save the traces and wiper fingers.. OldReno would know for sure.. All I know is that it helps with having the wiper fingers get back to zero..

2 and 1/2 turns is a good starting point.
But you need to first clean your payboard.
Be careful when pushing the spiral cam back onto the shaft of your 100 tooth gear.  Grab it firmly when you push back on so it stays in place.
Don't let spring overlap on itself.
Too much tension makes runaways on high pays.
Too little makes for short pays as hopper double steps on 1st coins out.

Ok.   Thanks AM & OldReno.   Took apart paydisc and 100 tooth.  The paydisc had a heavy sticky film on it and the shaft going through board for spiral cam had old grease, not alot but enough. 

It is still a balancing act to get wipers to reset when paying 2 coins and able to pay 250 coins. 
OldReno - You are right about spring not overlapping on itself.  Same spring set up will be different if overlapped or not.  Thanks. 

Right now it can reset for multiple 2 coin pays.   Pays 200 coins fine.  Pays 250 alright, occassionally overpays 6-10 coins.

paydisc ok.   Hole is round, pic makes it look oval.  2 tab is a rough at edge but 2 pays work.  Getting closer to looking at credit play.

[OldReno]

6 to 10 coin overpay perhaps due to outboard wiper fingers staying on tab too long. For example on a 200 coin pay, the outboard 200 wiper needs to come off tab in the middle of the carryover (CO) which is about 170 to 180 coins. The CO is hot on every pay, you just need outboard wipers to get your inner pay fingers up to it. I did a post on the CO somewhere. Good job so far.
ALWAYS check where your wiper fingers end up at on ANY miss pay....

[jimliner]

Thanks OldReno.   I will check.  I think the inboard are past CO before outers come off.  There some chattering at the end pay.  Like its trying to finish but wants to another coin or two.   

[jimliner]

Located and read explaination on CO circuit and outboards.  Going to check and set tomorrow.  Thanks. 

[jimliner]

Adjusted all the outbaord wipers. 
Wow, what a difference.  All pays are great.  And wipers zero on 2 coin pays.

100 wiper was leaving tab before inboards made it to CO. 

200 wiper was almost in perfect sycn with end of CO.   

250 wiper was still on but almost off tab at CO that ends at 50th tooth. Thats why it was chattering while paying the extra coins. 

Thanks a lot.  I dont completely grasp something till I see 1st hand. 

 Adding to adjustment/maintenance list.

Good job!  You get a gold star in my notebook!

[OldReno]

Make sure you put a little crimp in your outboard wipers (at the bend) to make sure they have firm contact. You should hear them snap when you lift and release them.

That coil is not greased up ... it is over heated. Check you fuses so you are not over fused, then remove the coil from the circuit and check the ohms for it. There is a chart that will tell you the ohms of coils online. If I knew where my chart was I would send it to you. When a coil overheats, due to a short along with over amping with a fuse thats over rated, it will overheat and burn off the insulation on the coil wires and cause an issue. Good place to start whenever I pick up a EM slot, is to check my fuses first.

Thanks Dave.   I think you are right.  The other night when repeatedly running high pays with door open, I kept thinking I was seeing the reflection of an orange glow behind hopper.  Wasnt happening all the time.  Even once I used hopper extension cable and turned off most lites in basement.  Didnt see glow when i ran a high po like this.  Anyways looks like i will be checking and replacing fuses.   Probably be changing coil.  I will have to see if I can find ohm chart for coils. 

Thanks Dave. 

[The Fatman]

good way to start all new repairs

It sounds like the coil be dying of old age or it could have been replaced with one possiblie under sized? Jon might know that coils size.

Machines don't hit high pays all that often. Be sure give machine time to cool down. You can mechanically step or wind up pay fingers by hand partway.

[The Fatman]

I appreciate the confirmation .... But Old Reno can give you the definitive answer on all EMi issues.

Daughter had softball all weekend.   I watched her team all weekend.  Didn't get time to dig in too much more. 


I did take have an hour to remove upper unit and look over.  Cleaned contacts on odds follower, odds step up disk and counter disk.  Looked over counter register for credit play.  The counter step up coil had the orange wires connected.  But the wires on other tab on coil were cut.   Using jumpers tested both coils, stepping up & resetting counter.  Both worked, and worked linkages for counter.   Connected cut wires back together.   


Reinstalled upper unit.   Switched bottom switch to credit play.   Left credits on counter before installing back into top cabinet.  When you plug in, it clears the credit.  Which is what I read somewhere.   Did a couple small hits.  Interesting.  It counts up win.  But immediately removes ~ 6 credits, feature lights remain on 6 coin pay.  The play credit button didn't work.  So I will be tracing that out eventually. 


That's was it for today.  Put back to coin play and all is still good.  I still need to do fuses this week and look at changing out coil on back of payboard.

Jim,  I was looking thru a EM Trouble Shooting Book I have a saw this on the Super Continental Credit button. I hope you can read it.

Jim ... I have one but only hopper payout, I have heard that there is a key switch right side that will operate the hopper to dispense coins...... might want to look that too ...

[jimliner]

Thanks Gary.   I was able to read it.   I used jumpers and was able to get both the  count up and count down solenoids to fire and move digits.   I still went ahead and cleaned each while fully extended. 


Thanks Dave.   There are two large banks of switches on each side of the bottom key.   The bank towards the front of the machine is for credit play, back bank of switches is for coin play  and hopper pay.  The back/coin play bank of switches are bent (maybe from being in that position so long) in such a way that  even when not in use they all make contact.  On my list to correct.  Slipped a small piece of a cut up business card between contacts to break circuit till I can pull straighten and clean.
