Bally 809 EM slot-Hopper Delay Relay Resistor Burns up on Payout

[TheDetectorGuy]

Im new here, trying to figure out why my hopper delay relay resistor keeps getting fried on payout.


Any insight in where to look would be appreciated. Also trying to figure if the is a wiring diagram or schematic for this circuit is available somewhere.


The Fuse eventually blows too after a while.


Thanks!

Would it be possible to add a photo of your situation and the model number of the machine.
Right off the top of my head, could be a dead short in the coil. If this is where one end of the resistor is connected.
The coil also adds some resistance, If there is a direct short, then there will be less total resistance, thus the resistor will be carrying
more load than design for. Also check all the contact solder joints for stray wires and or bent blades making contact where they should not.
Also the motor it self could be causing the problem.

I pulled it out previously to test a new resistor here is the photo of how it is connected it for temporary test, but it burned up too when payout hits, hopper motor turns , I'll have to test tomorrow for shorts on relay and overall.


Could it fry if the diode is bad (I didn't replace that.)


Relay connected to diode connected to resistor  connected to switch contacts..

Here are a couple of photo from the 809 I have in the shop.
Looks like the 10 watt resistor is missing.
Hopefully this will solve the problem.

David your photo is of the payout relate on the back of the hopper his photo is of the delay relay is 115 volt coil running on DC so versus the diode and a capacitor check your diode and capacitor if you keep throwing that resistor

Hi,  Also note that the delay relay circuit uses the little tiny microswitch that rides on the outer white wheel of your 100 tooth paygear behind the hopper board.  This switch opens every 4 or 5 steps of the payboard wheel (it falls in the notch), and this is what works the delay relay.  The delay relay is designed to momentarily turn off the safety timer motor.  When the timer motor turns off, the spring in it tends to reset the motor assembly back to its normal state -- giving the hopper more time to make the payout.  There is some kind of resister capacitor timing circuit involved.  If the safety timer motor continues running without being reset by the delay relay circuit, then it will time out the machine, turn it off, and the little red light that lives behind the hopper will turn on.  This circuit is used normally with a machine that uses X-circuits (the white donut type wheels in the top unit) during multiple coin pays, and the time setting on the safety time motor is generally very very short (look in the back at the timer wheel and you should see it is set at about 15 seconds or so IIRC)  (Normal type payouts -- machines not using the X-units -- are usually set for a much longer time).  The worry was that without this delay relay circuit, the machine could run away and dump out the hopper contents if one of the X-units fails.
You CAN eliminate the whole circuit, (I believe) by increasing the time on your safety timer motor, and then cutting out the hot wire to the delay relay coil and thus taking it out of circuit.  Of course if you do this you MUST tape off all exposed wires so nothing shorts out.  Hope that gives you a bit more insight into how it works.

Thanks Jon,
For pointing that out.
You know the old saying, two brains are better than one.
Well in my case, make that 1 1/2 brains.

[Jon]

Well Dave that means you have a half a brain so I guess we're at three-quarters of a brain
