wurlitzter 3310 not showing credits

i have a 3310 box that will not play the credits. the free play switch does not work either. i have a manual and the wiring of the free play switch does not match the drawing. as i am at home today i do not remember if the credits a regersting on the coin mech or not. any suggestions on where to start?

thanks

bob

Hi Bob,
Please read "Attn Newbies" ( above), and please enter your profile, and post your city ( or nearest large one), state, or equivalent, and country. This is now required to post!
As for your problem--not sure exactly what you are attempting to say ?
Are you saying that the "make selection" lamp fails to lite ? Is the "latch bar solenoid" energizing ?
The "coin mech" does not "register" anything--it only accepts, or rejects coins, and has the "add switches" in it ?--Are you saying that you did not look at the "Playrak"--that's what "adds/subs" credits--
Don't have any idea as to why the free play switch is not wired as per schemo--never had a problem like that to look at the circuit-- Ron Rich

i guess i used the wrong wording. first once a coin is dropped no select light comes on. 2 there is a box that is connected to the coin mech that has 5, 10 & 25 cent credit leafs to match what coin was dropped. 3 i think that this does move to add the credits. 4 once you drop a coin then the buttons never register the selection. 5 i have not checked to see if the button mech has the correct part number as the svc manual states but i know the wiring at the switch does not match. i can check more on monday. if the select light is bad will it stop the box from letting you select plays?

Hi rm,
Yes--wording is very "important"--no one but you can see what's happening, and if not worded exactly, anyone is open to errors in attempting to diagnose the problem. For "best results", and to give someone a "fighting chance", please use the wording used in the service manual.
BTW--is the credit lamp the correct one-is it good ??
Ron Rich

sorry for the delay. the coin register mech is registering the credits. the select light is good. as far as i can tell all the voltages are right. i have a svc manual and have looked at all suggestions on crediting problems.any suggestions on where to start?

i have ordered one of each relay 24vdc and 24vac to try in case one is bad on the lower unit.

Is the "credit wheel advanced", to the credit position ? Is the key switch making god contact ?
Ron Rich

ron,

yes the wheel is advancing. if you are talking about the key switch in the coin mech, yes it is. i have not actually checked to see that it closes the circuit but can do that monday.

I have seen those contacts fail--many times !-- Ron Rich

ron,

you were correct. me being in the electronics filed i should have checked the switch. the contacts were close but not touching. i adjusted and now the select light stays on without any credits. i tried the buttons and they will not stay locked. i am almost 100% sure that the light wiring was plugged into the selections buttons circuit board in the sdt lp plug. the other which is std tt if plugged into that plug the light does not light. the light is in the correct position (there are two) because it is behind the select word on the front of the unit.

OK--not quite sure what the "std" stuff you posted is about--If I remember right, there are jumpers for groups of records that can be classified as "Album-premium pricing", if the jumpers are moved from one socket to the other. For free play, they all should be in the "std" position.
When you say the buttons "won't lock", check the latch bar coil. See if it's getting ANY power, at all ( you can "use your finger"--just push on the plunger--if power is there, you will fell it "growl"). If it's "got some, but not enough" to pull the plunger, the NC contacts that are adjacent to it are NOT making. If that's not the case, check the select relay contacts. Ron Rich

getting back to this boxes problem. here is what i know. coin mech. is working when coins dropped. the select light stays on all the time. the solenoid on the keyboard does not entergize. using my hand, no resistance felt and if i manually push solenoid in and hold it to lock keys nothing is getting to electric selector. free play switch does not add credits. i have replaced all 4 relays on the electric selector.

ron, on your last post you were not sure what i was talking about concerning the std and tt. on the keyboard circuit board there are 2 plugs which the select light can be plugged into. on of them says std lp and the other std tt. if i plug into the std lp the select light stays on all the time. into the std tt no light at all. hope this clears up what i was saying.

You are going to have to get out the Service Manual/schematics, and read them--I'm GUESSING that "std" and tt refers to the "Top Tunes kit" ?? Is the key switch closed and making good contact in the Playrac ? Which 4 relays, did you replace--WHERE--please use terms in the Service Manual-- Ron Rich
