QUESTION: Hi Roger, I found the problem with the tilt was the 5 amp fuse..all was well until it hit the 3 bar jackpot/300 stops at 240 coins and blows the fuse..then I accidently put a 10 amp fuse in and I cooked the you have a source for one of these?  part # e-122-105..thank you in advance for all your help..also, do you have any idea why it would quit paying on 240 coins? and blowing the fuse..the hopper still has plenty of coin when this happens.


I was wondering how you did here on this machine so thanks for the update. Sounds to me like you might have a bad hopper motor, pulling too many amps and blowing the fuse out maybe. Did it just blow out once at the 240 mark, or has this happen before at just the 240 mark? This is a shame to see a electro/mechanical transformer go up in smoke as they are getting very scarce and getting expensive. I have seen a few hopper motors with burned motor armatures cause a lot of this fuse blowing on payouts on the later Bally E series machines but they use the same motors I think, and changing the hopper motors on them usually fixes this problem. Is this a large coin machine or a small coin machine, the large coin machine like 50 cents or a dollar coin, the hopper takes a larger motor, it's a longer motor for the large coin and smaller for the small coin 5-10-25 size. I'll check to see if I can find a transformer but I am not so sure I have one of those E/M transformers, but I do have a few hopper motors so you might take a look at the hopper motors armature and see if it is been hot, and shows sign's of being hot burnt and black.
Thank You

QUESTION: Thanks roger, it has consistintly 3-4 times stopped exactly at 240 and its a quarter machine..the hopper motor seems fine til we get the higher has paid 150 coins repeatly and it hits jackpots quite often..

ANSWER: The only thing I can think of right now is possibly that the hoppers Spiro cam spring has too much tension on it, this returns the Spiro cam to it's rest stop, if there is too much tension on it at rest, this could prevent it from going any further then 240 notches, and another possibility is you could have a burn mark in the trace for the 200 coin payout and this could also cut the circuit to the hopper motor stopping the payout. So I would check the hopper payout board closely for any burn marks, this is the board on the hopper that the Spiro cam and the Spiro cam wiper uses to step up one notch for each coin paid out.
Thank You

QUESTION: thank you Roger..i will check that and get back to you...

You can hand step that hoppers Spiro cam wiper and see if it will step up to 300 coins or more which would be about three full turns around, the 100 and 200 coin contacts will be at the right hand bottom and the 200 is at the right hand top I think, you will see the silver trace with two contacts that ride across it, if you see 200 on the one at the top, that is you 200 coin trace. After 200 steps the contacts should leave that trace and then use the 100 coin trace to finish the payout. If you can't step the Spiro cam by had 300 times then your Spiro cam spring could be set too tight and cause a problem there. Study this operation a bit, and then you should be able to determine why your payout stops short of the 300 coins it should be paying.

I am an expert on old coin operated machines, slot machines, trade stimulator's, jukeboxes, old arcade machines, etc. I have been identifying these for people who respond to my web site listed below, for a few years now. In almost all cases I am able to tell them about their old coin operated machines, the year, the value, and other general information about their machines. I do not know much about soda vending machines, coin banks, or scales, but I will try to help you with these if I can. Please email photo's to: My web site is at:


I bought my first slot machine, a .50 Cent Mills Black Cherry in 1969 and have been hooked from that time, I still have that Slot machine! Before that I found a open barrel full of old scraped jukebox wall boxes behind a restaurant, I wanted them all but never took a one of them. Anything that took a coin drove me nuts!

C.O.C.A. and other slot and coin operated machine groups, associations, groups, and clubs.

Many, the Coinslot magazine, always juken, Coin Slot Journal, Slot Box Collector, and others that I don’t remember at this time.

Graduated from Ballard High School in 1969, went to Edison Technical Collage for a couple of years taking welding and metal fabrication, tig, mig, heliarc, also arc and gas welding and fabrication. Then Apprenticed under a slot machine technician who worked in the slot machine industry Reno Nevada, and set up bar poker progressive machines in the casino's, and repaired machine and did the repairs on slot machine circuit boards there. He also was involved in the 2 hand dealer's market and bought and sold machines at the casinos auctions for the secondary market, which includes selling used machine overseas. I learned a ton from this man; he always had the correct answers and took the time to teach me the business. My interest and knowledge in other and older coin operated machine is for the most part, self-taught. It's been my passion from back in 1968 and before, my thirst for knowledge about these machines has kept me more interested over the years, and keeps me searching for more information even today. I have meet and talked to book authors on these machines, attended hundreds of coin operated shows and auctions, and I stay with that to this very day.
