ESERIES READER DIAGNOSIS FOR DUMMIES

[GOS]

Reel readers failures are very common on E-series machines - the usual method of identifying which reader is failing is by switching them around - once that is done you have a reader with a problem.  To make the diagnosis of which reader is failing and better yet which position on the reader is faulty - i recommend this non-technical method.
Each reader has 5 positions - comprised of 2 components - diodes / bulbs depending on the reader - all you have to be concerned with is that each of these positions create an address when one or more of these positions is working properly.
Each position has a value that creates the address (hexadecimal for the techies)  but for ease of understanding - the values are:
Position 1 = 1   Position 2 = 2  Position 3 = 4  position 4 = 8 and position 5 = 16
In this post we are going to show how the addresses are created and will be using a 22 stop machine (e1000/e2000 - 5v/50v - makes no difference).  Best to have a machine that has molex connections to the reel mech vs beauplugs.
With the machine POWERED OFF -  remove the P1 or M7 game chip from your CPU.
Align the 3 reels on the first position of each reel on payline (1st position is just after the seam in the strip)
Now POWER UP - the meter will flash 888888 then 123456 - press the test button on the hopper 5 times to go into reader mode.
Your win meter will show .1  22  if the first position is reading correctly (the 22 is comprised of position 5, 3 and 2 - generating a value of 16 + 4 +2
If any one of the 3 positions are failing then you will get a value other that 22.  Using the chart provided - find the address  you are getting on the left and it will show you which positions are valid.  For example if you get an address of 20 the position 2 is defective.
Move the reel one position at a time and the address will change - 1  21,  1 20 etc.
To test reel 2 and reel 3 - press the coin switch trip wire and the code will change to .2 etc.
Hope this makes sense - once you get the hang of it - it will be easy as pie.
