I have a Stern flight 2000 and lastnight one of the coils cooked on me, it was a J 26-1500. I was told that I could replace it with a AE-26-1500 coil, is that correct? How can I find out what coils are interchangeable?
 
coil info

not sure what the J and AE stand for but the 26 is the wire gauge and the 1500 is the number of turns of wire on the coil.......... so it should ohm out at the same value as the old coil

You'll also want to figure out why the coil fried before installing the new one. My guess would be shorted driver transistor.
 
That's my plan, I just ordered a new coil from Marcos pinball but before I put it on I will look at why the original fried. The previous owner did replace some of the resistors on the driver board and under the new ones the board is black from being burnt so I want to make sure that the new resistors are the correct ohms so I downloaded the schematics for the driver board. I also plan to check the driver transistor for the coil that fried. Something is not right on the solenoid board, since those resistors burnt up burning the board.

The "J" designated a Stern part number.....the "AE" is Williams. Electronically speaking......26-1500 has been mentioned above. That is the same on each coil.....so, they are the same.....electronically. The only issue you MIGHT run into is physical coil size. The plastic bobbin on the "J" coil could be slightly smaller or larger than the "AE" coil......leading to installation issues, binding, or just straight up won't fit.

Looked at the solenoid board today and the previous owner replaced the SE9302 transistors with TIP 122, not sure if it is a coincedence but that is where the resistors burnt up and burnt the board. I removed the TIP 122 and replaced them with TIP 102 transistor which I read are the replacement you are suppose to use for the SE9302 transistor. Not sure if that was the cause of the problem but I haven't had a chance to check the power outputs for the solenoid board yet.

A TIP122 is an acceptable replacement for a SE9302......a TIP102 is a better replacement.

I just want to chime in here and say NEVER NEVER NEVER NEVER EVER EVER EVER EVER let the "pinball medic" work on your machines. This guy worked for our company for a few months, then figured he learned enough to quit and try to make money on his own. A lot of people here in Austin have lost money he accepted for "parts", and I think some have lost complete machines. A few had to threaten lawsuits to get their machines back. One machine supposedly had a bad flipper. He took it to fix and "clean up". A couple years later when they finally tracked him down (only contact is via e-mail) and threatened to sue, he dropped it off in their driveway when they weren't home, half disassembled and with lots of parts missing. We've had about six machines come to us in the past year that he "worked on" first, and all were worse off than when he started.

While the information on his site may be good, it's all been cut and pasted from other resources.

Just a word of warning to anyone in the area who may be considering him for a "cheap" repair....
