Coils and power

[JMP]

Hopefully the last job on my JD (for a while anyway)....



Sniper hole ball popper is weak, not always firing the ball out of the wire chute. Was advised to consider a more powerful coil. Manual states it should be an AE-23-800 but have an AE-26-1200 installed currently.

Both are described as 'general purpose coils' at PH website but not sure if worth installing the AE-23-800 as per manual or go for another more powerful. If the latter, which should I use?



As it stands, I've checked the armature, ball topper, grommit etc. and it appears to move freely so not sure why it's failing....



Thanks all.

As the manual states you do need a 23-800. And seeing that your soldering skils are inproving the change over should be a piece of cake.

P.M. me your address in case I can't find it and I will send you over a coil, or if you can wait I will fix it at the Northern lights show at the begining of next month.

A 23-800 coil is 50% more powerrful than a 26-1200. A23-800 is the most powerful coil used in a bally/williams

Thanks both of you, just read these after being away at the weekend. Obviously had the wrong coil fitted then by the previous owner.



Darren, much appreciated, address on its way. The more jobs I have a go at myself, the better. If I mess it up, I'll shout you in November ! Cheers.



For future, is there a way of distinguishing all coils and their powers? The coil numbers don't mean anything to me.... Thought I saw a site somewhere stating power reflects the colour of the coil paper (?) but can't find it again now.

In quick terms, the lower the number after the hyphen the higher the power. The first two numbers designate the thickness of the wire, and the later number is the number of turns on the coil. Lower turns means higher current = higher power. Eventually if you kept decreasing the number of turns, it would use so much current that it will melt.

Thanks for that and the link.
