Alternate coils
« on: February 18, 2013, 08:57:18 PM »
I'm actually after a replacement for a F-36-7000 coil which is a small coil on the side of the coin mech on my Bally FG. Now this isn't the only coil I have had trouble tracking down and as I'm not very technically minded I wondered how you can find out what alternate coils are good replacements for some of the original ones which may no longer be available. For example, there must be hundreds of different coils from lots of different manufactures, I'm sure some of them can be swapped from one machine to another and still do the same job without overloading anything. But how can you tell which ones can be swapped?

Thats a lot of info to digest.
basics are that F is the size of the coil.. so bottom line is that whatever numbers you replace with.. the F is a must or it may not fit.
36 is the gauge or thickness.
7000 is the number of turns.
Ratio of turns to gauge determines the amount of current your coil pulls... its this current value that you need to match.. you can go slightly under with no real noticeable effect to coil strength but never go over.

To work out a replacement coil you need to get to the same value.. this is where those that dont like me doing a bit of maths tend to turn off.

The current =  voltage X ( number of turns / gauge)

Make sure its an  F  ( physical size of the coil)  and equal your current number and all is good.. can use a substitute with no issues.

Doesn't matter what you order or where you order from, 5 min later and you need something else!  Story of my life.  *!@
