How to make and use jumpers, Part 2


Now that we have our jumpers, and know how to test our 6V bulbs (Part 1), we can go on to testing our 50V coils.
The 50V coils always have an orange (70) wire on one side.
The other side of each and every coil eventually makes its way back to the Yellow (30) wire.
Here is how to test 3 coils easily, the coin lockout coil, the coin diverter coil, and the handle release coil.
With machine on, clip one of your jumpers on to the 30 wire on the coin in switch on the door.
Touch the other end of the 30 wire jumper to the NON ORANGE side of your coin diverter coil.  You should see/hear the coil pulse.
Remove the coin acceptor, and touch the jumper to the NON ORANGE side of your coin lockout coil. You should see/hear it pulse.
Now, reach way back and touch your jumper to the NON ORANGE side of your handle release coil.  It should release the coil.
If any of these coils do NOT pulse, then chances are it is burned out (open) or you are missing the 50V which should be going to it via the orange (70) wire. 
In that case, use your other jumper, and clip it onto a good known 50V source (solid orange at the transformer) and then run it to the 50v side of the coil.  In this case you DO want the 50V source jumper to touch the orange wire. (but NOT the yellow wire jumper...)
\
To test the other coils in the machine out of circuit, clip one of your test jumpers to the orange on the transformer (or somewhere else handy like the other side of your coin lockout coil on the door), and then clip it onto the Beau pin plug on your unit under test that carries the orange.(or onto the orange side of any of the coils in the unit (they're all connected)  Then, using the yellow wire jumper (from the coin in switch is always handy) touch the yellow jumper to the NON-ORANGE other side of the coil.
I hope that all makes sense.
You can test all of your 50 v coils out of circuit this way, and determine quickly and easily if they work or not.
Be careful when doing these tests that you do NOT touch case, or you may blow the 50V fuse, and if you don't realize that you have done that, you may be spending a lot of time looking for a problem in the wrong place, when it is a fuse problem that you created after all.  Hey, it's happened to me, too.

Thank you again Reno.  Last night I think I developed a 50v issue.  Coins just drop through on my 809.  No click at all when I actuate the coin switch with my finger.  I read on of your how to test the fuses with the door closed posts and I get no click when I pull the handle with no coin in. The fuse looks good.  I even switched it out and still no 50v.  I will give it another shot this afternoon.  I have to locate the archives and all of your pearls of wisdom.

I have the same problem with no click when I hit the coin switch. Did you figure out the problem? I see I am here 6 years later. I hope you see this. It is driving me crazy!! The machine was working just fine.

RiseLikeRa:
Picker I did fix the problem but I don't remember how.  Repost your question under a NEW thread and the wisdom will flow.

Thank you so much!!!
