DS100 Sevice Switch

Ron silence sounds like you don't think it is a good idea t work around that switch. I guess we will look for one.

Joe,
No, I did not see the last two posts till now--but you are "on your own" if you jumper around--
If the "free play switch" is dead, will the coin switches work ? If not, is the 1/2 amp fuse good--and the correct size ?
Also, if you leave the "bat handle" in the center position, then slide the black switch, can you hear any "clicking" comming from the rear of the TSU ? Ron Rich

Hi Ron I was able to obtain a much more legible schematic and now I has reassessed the problem. The service switch is not the issue. It looks like the voltage we are missing at the junction of fuse 421 and fuse 422 is supposed to come in a straight cable run from pin 5 of plug 421. I don't know if there is a broken wire or what. The schematic just shows a straight wire link between these two points. guess we are going to have to dig into the pricing unit and see why no continuity. Sorry for giving you the wrong dope.

Both of the fuses 421 and 422 are good but the 25 ac voltage that is supposed to feed them is missing.
