Sweep stays at 66 Degrees

[Doug]

I have a lane that is being very stubborn, on a first ball cycle the sweep goes down to 66 degrees and stops then the table goes down and picks up the pins and returns to the top and stops because the sweep never runs to sweep the deck. When I put the machine into a 2nd ball cycle everything works fine, I have swapped chassis but still have the same problem.

Please Help!

TB switch adjustment or switch bad?

Hi Doug!

Doug, TA2 turns on pindication and initiates sweep run-through,

TB and SC are the interlock cams.

Your TA2 switch may be bad or the cam switch button is stuck in. Clean the switch with an electrical solvent and push the button in and out several times to see if dirt is holding it in.

If not, a TA2 switch change should solve the problem.

Jerry, shame on you :p

Re: Sweep stays at 66 Degrees

On a '70, a bad/malfunctioning OS switch can sometimes cause this, too... usually with SS upgrades (Omegaboards, etc...) and MP's, but almost never with 5-boards. If it 'twitches' for just a second, it will cause the sweep to stop, but allow the table to complete a normal run-through instead of stopping after 1 revolution (with the pins hanging out of the grippers).

like King Stalk & Gman said:

replace TA-2 switch (why arent table cams TA/TB/TC)? and check/replace or just disconnect the out-a-range switch for a while see if it calms down

but normally that kinda thing has always been the omega-board. but you say you've changed chassis.

Re: Sweep stays at 66 Degrees

I had the machine turned off for awhile, got a few replys and went to check it out, but when I turned the machine on and cycled it to duplicate the problem, IT WORKED imagine that happening
HA HA! Oh well league is using it now and no sign of a problem for now. I will be replacing micro switches tomorrow though just in case.

As always Thanks for the help!

Also look out for a worn out sweep shaft/crank arm!

Re: Sweep stays at 66 Degrees

Coors is right, I didn't see that the table stops. If it stops with the pins still in the respot cells then a wire is off the offspot switch.
