WARNING: This post contains more information than anyone ever wanted or asked for but is very good to know when troubleshooting a potential coil issue, and is not manufacturer specific in any way.
Quoted from PinMonk:If you are really concerned about it and have a multimeter with memory, you can check the amount of power going to that DR-3 but hooking the multimeter up then manually firing the coil (that doesn't exist) and see what it reads.
No need to do this, all you have to do is measure the resistance of the disconnected coil, the amount of current it will pull is the 48 (coil voltage) divided by the measured resistance as [ V (volts) ÷ R (C) = I (amps) ] 48V ÷ 10.7Ω = 4.49A; this correlates to 215.33 Watts as (W = V * I).
Realistically, all that matters is the resistance of the coil, if it measures close to the same as the other 26-1200 than its more than likely fine. I assume that Stern is sending you a replacement coil for this.
Quoted from PinMonk:Everything has a failure rate. You just finally became one of the unlucky 26-1200 stats for 2019 with this Star Wars coil. I wouldn't read too much into it.
This is true; however, the fail rate of node board current sensing and/or coil control circuits is going to be significantly higher than that of a coil. The best thing to do before replacing any coil is to measure its resistance, if the resistance is correct then the current it draws will also be correct based on the voltage applied.
Merry Christmas.
