Title: Coinco 755-9800
Post by: on February 21, 2004, 03:57:06 pm
I've got a coinco 75-9800 in my cavalier.  The changer is set for 25 cents, and most times works fine.  Once in a while, when you drop a quarter in, it still releases the bottle, but also will give you change until it runs out of nickels (sounds like a slot machine).  Is there a fix to this, or it is rebuild/replace time?

Thanks!
Jeff

have you cleaned that coinco 75 9800 out.  checked to make
sure nothing is sticking or jammed up .
Going through the manual  it give a couple of things
Defective Motor Pulse switch or
replace logic board.
That is why I say give it a good cleaning first. ?

Pat P.

P.S. what kind of Coinco  S75-9800A or S75-9800B
also let me know if you would like a copy  of the manual

It's either a defective motor pulse switch (that counts the payout motors rotation/cycle,) or a defective logic board
check for a stuck/loose/cracked microswitch, loose wires/connectors going to the switch, if they seem ok, then looks like it's time for a new logic board (from a doner unit, or other source) or replace the mech ( keeping yours for spare parts)  :(

Thanks for everybody for the help.  I found corrosion in the electrical connections for the change dispenser.  I'll try to fix this mess later, just ordered a 'reconditioned' one from premier vendors.  $30 inc. shipping, hope it works right!

By the way, it is a 9800B

Bonus question for future reference, will a 9800A interchange?  What is the difference between  the two?

Basically it's the price settings/switches & printed circut board (electronic-logic board) the "A" has four switches & can go up to 75-Cents, while the "B" has 5 switches & can be set up to $1.85.  Although the two logic boards look different, they are in fact interchangable between the two models ( "A" & "B" ) in regards to function, (but not pricing-range obviously)

Also the "B" has a plastic molded coin-reject path cover & the "A" has a metal one covering it's "reject" path

One other thing I'd check is the .25 switch.  I had one that started going spuriously bad.  It would send erratic signals to the circuit board, in essence looking like quarters were constantly activating the switch.  The coin unit was set for .10 so the payout motor would continually run paying out change.  Use a multimeter to check resistance across the switch.  If it jumps between infinite and 0 (or anywhere under 100 ohms) without being actuated, it's bad and needs to be replaced.
