How do you see if both coils are firing?

Check the fuses first, one for each big reset coil.

Check the wires to each coil...is the whole wire soldered on or just a
couple strands? A couple strands might work for a lamp, but never for
a big coil like those.

Unsolder one lead from one coil, make it try to reset. It won't be
able to reset all the DT's, but you can see it try.

Repeat for the other side.

I don't have aKingPinor a print, but there is probably a sequence
completed relay driven by switch on the DT bank that closes when all
DT's are down. If any of the DT's reset, the sequence shouldn't fire
and the coils shouldn't try to reset. One DT up should be enough. If
it still tries to reset after one or more DT's reset, check switches
on the sequence relay.

OK, so I checked the fuses...both good. The wiring looks like it's
OK, so I skipped that for now. Checked the coil stops, both look
good.

I took a look at where the coils were located in each bracket and
noticed that they were both set at the highest point on the
bracket...seems like at this position the coil plunger isn't going
down far enough into each coil to do a proper reset each and every
time. I adjusted them and moved them down to the lower position on
the bracket. Played several games and they're much resetting more
consistently now......although still one in every seven or eight
resets doesn't work.

Wondering about the link/pawl that attaches the coil plunger to the
reset bar, should the hole it it be round, or is it supposed to be
oval/elongated? Any areas that I can lubricate on the DT assembly?
Any other ideas?


again the coils are firing each time, jusrv
.
