Seeburg hf100r - Part Inquiry

I have not checked the Service Switch yet, but wondering if all this is also causing the low level shock you get when you touch the machine frame (when barefoot on concrete garage floor), has to be a ground issue. I will work on the Service Switch tonight and see what I find out.

As for an open wire on the Mech, I went thru the schematics line by line last night and did not see any meter issues or visible issues regarding the wires, but you never know .

OK so I think I may have narrowed my problem down.

So I took out the Service Switch completely and first verified all of the contacts were ok and positioned properly. I then tested the resistance from each connection in the switch to the representing prong connection in the plug head, all came back fine except for prong #2 no resistance at all. Looking at the schematics in the manual (pg 1225) it shows that wire is feeding the Trip Solenoid, since I am not seeing any resistance on that wire I am assuming it is broken in the plug which is non-accessible to repair, or maybe somewhere down the line (would need to remove the fabric shield to find out). And if this is broken that would give me the reason why I am not seeing VAC at the Trip Solenoid.

If the wire is loose from the prong in the Service Switch plug, how would you go about repairing that, or at that point do you replace the entire thing?
Does anyone have a Service Switch for a hf100r?

Hi Ron,
If, in fact it is open at the plug, you simply cut off the molded plug and replace it--You MIGHT try heating that pin with a soldering iron first, just in case it's a poor solder joint (nothing to loose). I would also first strip some of the cloth off near the plug and find that wire--measure it both ways to locate the open, then proceed to repair it--Ron Rich
P.S. If you are unsure--jump that wire, on the socket, from that pin to the service switch, (or to the pin that the service switch connects it to), and see if the phonograph will now function ? If so, you can either leave it "jumped", or find the open at your convenience.

So I tried to resolder the plug by heating but did nothing, did not expect that to work, never did with my pinball machines but its worth a try, you never know.

But I cut wire #2 about 3" up from the plug and the wire from that point back to the switch was fine. So I have a jumper running from that point to the connection under the receiver and WOO HOO!!!! I can pickup the selections made automatically. So I will have to look for a new plug or an entire new Service Switch assembly.

A fundamental process question for this machine, now that I have it working. When a selection is made and completed it rejects the record and moves to the next selection. When it finishes the last selection and there are no more credits available, should the record be rejected back to the rack or does it stay in the turntable? When mine finishes it releases the record from the clamp but does not put it back in the rack, is that normal? When I pick a new selection it will put back what it has and scan to the next selection... Just curious if that is a normal process.

Ron,
Glad you found it !! Now for the next question --- RTFM !!!! ( or my "Seeburg Mechanism Guide"--"--mechanical sequence of operation") ( and the "stickies" posted above, for a plug source). Ron Rich

Ron Rich....

After all this poor guy has been thru, Are you really not going to give him the answer to that last question?

Yes Ron V, That is perfectly normal processing for a 1954 Seeburg HF100R.... That said, Read Ron's manual... its worth its weight in gold.

Hi Jeff,
RTFM IS, The ANSWER---
Nope--iffin it were my intention to answer it, any other way, I would have ! But, on the other hand, I knew one or more of the "blabbermouths", would soon do so -- ( Have you no consideration for how hard I worked, coming up with that diagnosis, to his original problem?):lol: Ron Rich

Yes Ron, I wouldnt expect you to answer that specific question any differently.... and under the circumstances, thats OK because luckily... this board always has a Blabbermouth or 2 lurking in the backround

All kidding aside, Please keep up the good work, as we all know that this board would not be as Great as it is without people like you sharing so much information with others as well as showing a great deal of patience...

P.S. I'll have you know, your Mechanism book is always nearby when I find myself in a Seeburg pinch.

Sorry about that, was lazy and did not have the manual handy when asking the question. I did find the Operational Sequence and see this is a normal aspect for this machine.

FYI... I did buy your book from Amazon the other day, just waiting for it to arrive.

Thank you again for your help, tracking this down was entertaining.

Hi Ron,
Thanks for purchasing it--enjoy it--had you purchased it directly from me, you would have had it in two daze--
