just fixed a "machine gunning" issue out of the SPU1. box now acknowledges a quarter and lights up "make selection", takes a letter and number and HOLDS DOWN but does not release them and begin scanning. if you manually go to the SPU1 and push the plunger in the cancel solenoid, it cycles the assembly and credit wheel, acknowledges the selection, releases the button on the ES, and cycles the mechanism. Picks up record, touches needle, and returns to scanning and then stops at it's rest point on the right end of travel. YES i'm going to search the trouble shooting section of the manual tomorrow once I get to it; but I know i'm going to be here anyways and start asking questions.
thanks in advance kevin |

Kevin,
What/how, did you "fix" to stop the "machine gunning"-- I would bet this is part of the new problem--

ron,
1 o 2 things, not sure which. either additional filing/burnishing of the y contact, or the S contact being grounded out on the capacitor side when in the open position. moved the wires a bit once finding where the grounding was occurring and continuity measured accordingly when the switch was closed and opened. plugged it in and quiet as a mouse!
kevin
PS-let's remember that 1 capacitor was also changed as noted in another post. it was #21 on the SPU1 parts list, P/N 86235. not clue if it was even bad. replaced with one that was out of a kit, labeled c-25 I believe if that means anything. it was rated .47 and 250V I believe. would have to double check on those number ratings though.
when I manually push the plunger it cycles the whole thing and clicks the timing relay as it should.

Kevin,
IF, that new cap is a .47--it's wrong ! It should be a .047 !!

good news, the cap is .047, NOT .47. so it seems we're good on that end. talked with a few others about this too; told to do a few checks in the backside of the selection receiver. waiting to get out to the box again and do these to see what it tells. will keep posted, and any other thoughts in the meantime please share!

Kevin,
What are you using to "measure continuity" ?

ron,
use 2 different meters for this entire project. one out by the box, and one at my house with the SPU1 when I had it here. both were digital I believe (digital read out). in this particular post I mentioned continuity and having a ground where it should, for that one I used my blue point digital meter.
do you have some continuity checks you'd recommend I try?

Kevin,
Checking continuity with a digital meter, as written in our FAQ's section, will not test the contacts ability to carry current ! One must use a good Analog meter, for this test.
I suggest you test all contacts in the SPU and TES this way--

box is moving along slowly and surely. acknowledges and cancels credits (3/quarter), accepts selections and scans when selection is made, but still doesn't play. sometimes it DOES pickup the selection, othertimes it's a random one. ALWAYS picks something up when selection is made. picks up touches needle and spits back. just wanted to give an update on where we are. the buttons not being held down ended up being an issue with the stepper circuit thinking a wall box was hooked up, thus disabling the ability to select on the jukebox itself.

Kevin,
It sounds as if you either have a read-out problem on the mechanism, or in the TSR. Check it by doing the battery trick.

ron,
little confused on the battery test. take the d battery and ground the neg to jukebox chassis. take the positive and just touch the tip of the RCA plug from the tormat to it. then it says "re-insert the cell"?? after touching the B+ to the rca tip, do I plug the RCA back in and make a selection? Once this is established it sounds like it should scan and pickup every selection?
also, what exactly is this test doing by touching the battery tip and whatnot?

Hi Kevin,
Naw--it don't say "--re-insert the cell" ( anymore !)--it reads "re-insert the plug" ( thanks !)
What you are doing is "flipping" each and every Torrid, to the selected state. "People" often word this as "Writing-in". NOT true, as you are going thru the Read-out loop (back door ?), in doing this. Look at the service manual or how the TMU works ( or go to our FAQ's and see the late Tony Miller's site--he explained it well). Ron Rich

success. between oiling the mech and the battery test allowing it to continually run and move all the parts in there; it broke something loose and works! great feelings when that happened! on to the next issue though! doesn't always play selected records, kinda seems like it's picking whatever ones it wants towards the left of the magazine and none in the middle or right?!
