Since this thread is a few months old without action, I’m going to try to hi-jack it for a similar issue.
I recently purchased a Blue Chip and it has one of these reset banks for the 1-8 numbered targets. All the targets trigger correctly, but the reset only worked once out of about 30 restarts. The entire machine was inoperable when purchased and I’ve been cleaning 40-some years of filth out of it and adjusting as I go.
The reset coil has power, but it appears to not be strong enough to push the reset through the complete cycle. I’ve got a twin of this game that seems to be doing the reset just fine and the coils have the exact same ohm resistance.
What is the next logical step here?
1. Rebuild the coil.
2. Remove the entire target switch assembly, clean all the joints, and apply dry line bike chain lube on the connecting rods/pins?
3. Use hammer.
4. Other. (Please specify)
