Excessive arcing from SE100 paddle switch

[bjwizzer]

I obtained a Seeburg SE100 and am working on multiple issues to get the box running.

I have noticed that the contacts on the paddle switch have some minor arcing which I think is normal,
but every so often when the mech scans to the right there is quite a large arc from the contacts.

I have checked for debris and bridged contacts, every physically looks ok.

Any ideas or suggestions would be appreciated. 

Thank you in advance,

Hi BJ,
Yep--sure do, but ain't gonna re-write it all over again--read our FAQ's section--attsa why we have it --for Frequently Axked Questions !!   Ron Rich

"Forgive me Father Ron for I have sinned" 

I bought this SE100 for $75.00 on Craigslist, when I picked up from the Seller I was amazed at the overall condition.

The SE100 was in very nice condition and the record mech was really clean, it looked like someone cleaned the entire mech
using some type of cleaner.

I removed the mech, amp, control unit and front door to lighten the box because in was in his basement and he was
"fussy" about causing any damage.

I got the SE100 home and found following issues;

1.  2 bad casters - fixed

2.  the run switch on top of the mech was broken apart so the motor would not run.  I fixed it by replacing the run switch with a voltage selector switch from a PC power supply.  fixed

3.  with the motor running I lifted the release lever and saw the record transfer arm would not lift high enough to load a
record into the mech.  

4.  I lifted the release arm again and the mech would not scan.

5.  The mech while nice and clean was "never" lubricated!  So the Detent Arm lever and Gear Segment asm were
severely binding on the shaft.

I lubricated the mech using the Seeburg Lube chart, I was able to free up the Segment Gear asm but not the
Detent Arm lever.  I even tried some PB Blaster but that didn't work either.  I found if I heated the Detent Arm arm
it would free up but bind up again as it cooled down.

So I disassembled the mech far enough to remove the shaft, detent arm lever and segment gear asm.

I spent over 5 hours performing this whole process and I was tired out!

So when I tried testing the SE100, that when I saw the excessive arcing and created this thread hoping
for a quick fix answer.......my bad.   (my sin)

Since then I have read the FAQ on contact cleaning and adjusting, I even printed it to take to my shop.

The good news is the mech now transfers the record in the mech and the mech now scans, but
the SE100 won't pick a selected record...oh well, ever onward...

Ron,

Yes, I have a manual, bought it on eBay, some of the schematic are blurry, but I'll deal with it.

I have a SCC9 Code A control center and a TSA9 Code A amp.

Like I said I was worn out after fixing the issues with the mech, I have not cleaned/checked the "detent switch" or the
"contact plunger block.

Boy was I glad I had an old mech to use as a reference before disassembling the SE100 mech.

"note" I drilled an 1/8" hole close to the center of the detent lever arm, that way oil can be applied directly
to the shaft in the future.

Ron, is there a "good" troubleshooting" guide available to buy, I have checked my other Seeburg manuals,
none seem to have anything on troubleshooting.

As always, your help is much appreciated!

BJ

Hi BJ,
Nope--Seeburg did not write a trouble shooting guide for that, or either LS-1/2 model--You can somewhat use the SS-160 guide--
Check the 56k resistor on the control center PCB--If that board is a -2 board, it will be a 4 watt resistor--if a -1 PCB, unless changed, it will be a 2 watt resistor--change it to 4 or more watts ! Check the read out "fingers" under the TMU--check the detent switch--and the clutch reset switch-- Have fun, Ron Rich
