I need to replace the left shooter coil on my JD and only have a AE-26-1200 in my spare parts supply.

I was wondering if this is a suitable replacement or do I need to replace it with a AE-25-1000 which is in the machine currently.

Google pinball coil resistance chart. Find the resistance of each coils. If less than .3 ohms or so, you should be ok. Lower resistance than factory = more power. Higher resistance = less power.

*NOTE* .3 ohms is less than 1 ohm. Not 3 ohms.

There are lots of variables here, length of wire, AWG of wire, plus toss in thermodynamics and the calculation required are extensive; with that being said, the AE26-1200 will be significantly weaker than an AE25-1000 as not only is the wire smaller which increases resistance but there are also 20% more turns on the bobbin (1200 vs 1000). These factors out of the gate make the AE-26-1200 a much weaker coil, but it will also get hotter faster further increasing its resistance and lowering its power.

I would say that this would NOT be a coil you would want to install as it would be at least 30% weaker out of the gate at room temperature and only degrade further from there.

The part numbers tell you everything:
AE-26-1200 is 26 gage magnet wire spun 1200 turns on the bobbin
AE 25-1000 is 25 gage magnet wire spun 1000 turns on the bobbin
