I had one of the diverter gate coils (26-1500) on an F14 fail, and I since I have a new 24-900 coil in my parts box, I am looking for suggestions on whether I can use a 24-900 in its place. I would add a diode.
hard to say without a resistance comparison since the winding gauge is different.
you probably want the right coil here. a locked on / shorted f-14 shorted diverted coil is known to blow up the special solenoid driver section.
The 26-1500 is 13.6 ohms the 24-900 is 5.3 ohms I wouldn't use the 24-900 it's a lot stronger and not intended to be eneregized the length of time diverter coils are held.
you need the correct coil. the 24-900 is way too low resistance. you'll smoke the coil and probably the driver transistor too.
I hear the advice and I will not use the 24-900, thanks.
Is a 26-1200 an ok substitute for the short term?
The 26-1200 would probably be fine. If you have a 1 ohm, 5W cement resistor I would add that in series (I know, I know....not a part you would commonly stock, but they can be found on a lot of classic Stern 3 and 4 flipper games if you have parts stashes.)
