Seeburg LS1 write in problems

I am new to this but do have experience with pinball machines and do learn quickly. Anyway, I have a seeburg ls1. And when a selection is made the noturious scans twice and dose nothing problem occurs. When i trigger the lever manually it picks up the 45 and plays all the way though, returns it and then same old problem when another selection is made. I tried the battery trick did nothing (perhaps im doing it wrong?) and have no voltage at the "write in" test points on the control center. Where should i start before i spend unessary money? Fuses? electronic components? I do have a service maual on hand. Any help is great. Thanks

Hi Pin man,
Start by telling me which Solid State Control Center is installed in that phono--- Ron Rich

Sorry for the late response. I was tied up with flooding. Anyway. Pin man? I like that one. No jukes or pins lost. It has a scc7 in it.

Pin Man---
You need to find out where that Write in voltage has flown too--Check the 150 VZD--

Finally got my basement all together after a flood. I'm sorry i sound stupid, I'm still learning. Please clarify "flown too" you mean something shorted and it's sending the voltage else where?

I mean "disappeared" where too?--that's what needs to be determined-- Ron Rich

ok, thanks. tomorrow ill hook it all up and see where i can find it.

Pull the SCC-7 out of the phonograph and check the test points on it-- Ron Rich
