La Plata, MD
Does anyone know who sells new switch blades for early SS Bally flipper buttons? I need to replace mine.
Thanks,
Brad

Quoted from Dent00:Is this it?
No. EOS not flipper button and low power. Those in the picture are burned, high power.

Yes the contacts are very bad, pitted. I blew the 43V F4 fuse and have been looking for the source of the high current. Do you think my flipper switches could be causing it? The flipper units are pretty much all rebuilt with new switches and coils.
Thanks,
Brad

No, just not enough power.
Your EOS not opening soon enough more likely blowing the fuse.

Cool Thanks for the link.

I guess this is what blew the fuse? Any idea what might have caused this?
Thanks,

You missing a wire on that coil ?
LTG : )
Not sure. I desoldered the power wires and pulled it out. I basically built new ones from looking at the old ones. Maybe they were not wired correctly. I might be in over my head.
Quoted from LTG:Please get help if you need it.
Carefully study vid1900's guide.
I was referring to your picture, red arrows point to where some wires might go.

Here is the how it was wired up on the playfield before I removed it.

The power wire, assuming the green on the RHS must go to the banded side of the diodes.
Helps to have same colour wires for the EOS switch, and different, as per schematic for flipper power and ground, different colours.

The cathode on both diodes are facing the switch. The positive voltage is supplied by the brown wire.

but I don't see the other windings coming from the coil (under the wrapper) to the middle and left hand lug in top pic.

Here it is. It does look like it is not there in top image.

The other wires don't go as suggested in post #12
Only one (either one) of your EOS switch wires goes to the middle lug.
The common brown power wire goes to the right hand lug (in the pic above) where you see the grey/silver band on the diode.
Your EOS (end of stroke) switches are wired correctly and must have continuity across them, zero resistance, meaning they must make perfect contact until opened by the flipper crank. The gap of the opening should be at least 3mm or 1/8th of an inch when flipper is at it's maximum travel.
Your other coloured wired (green for the left) goes to the left hand lug.
On your right hand coil it will be an orange wire to the left hand lug.

I figured out what problem was. The EOS switch was opening but one side of the contact was barely touching, so it was not open at all. Oh well time to buy a new coil. Thanks for helping out.
