Quoted from Hawk007:
Hey rotordave Yes there is a diode on that coil. just verified on my machine .
Thanks guys! I‘ve had a GI for about 15 years, this is my second one, I sold the first one a few months back when I got this one, as this one has a nice PF and cabinet, even though it was half missing.
So, coil wise, so far we have 1x diode, 1x no diode. lol!
Same as when you google the part.
The manual refers to “diode tieback” which is what made me think about it. Other WPC 20v coils are no diode.
More data required.
PS the GI manual appears to have a lot of errors in it. The factory molex plugs are wired different to the manual.
