I WAS going to ask where I could get a manual for Stellar wars so I could figure out how to change number of balls (currently set on 3) and change the sounds ( I was told this was possible)..

But today, I went and turned it on.. and NONE of the back box lights come on.. like the 20 or so little bulbs.. and at the same time 4 lights on the playfield.. (the 4 that separate the alleys that the ball can bypass the flippers and you lose your ball on both sides)

I find in the back box 6 (or was it five) fuses.. all "look" good.. although I did not take out and test them w/ DMM yet…

Something simple? Just not getting power to them I guess… worked great when I turned it off last night...

Maybe a manual would have what I need for this new issue too?

Here's your manual for Stellar Wars. Neat looking game.

As to your lighting problem, there isn't much it can be, as the GI lighting on those systems don't involve the circuit boards at all. Definitely throw a meter on the fuse, It's that one lonely fuse on it's own separate holder, not on a circuit board. If the fuse is good than I would check for the 6.3v AC power at the fuse block.

Thankfully, there are only a couple potential problems with it. It's either the fuse, the wiring, or the transformer. Here's the power circuits from Firepower, should be essentially the same as yours.

I tested the fuses in the back box.. all good...

but see there are some more under the play field.. was gonna see if the play field lifts up and to access those and test...

is the fuse your referring to under the playfield or in the box?

I tested the wiring that feeds the braids that connect all the lights in the back box.. no power there.

is the transformer in the power supply in the metal cage?

there are a few lights on the back box that DO work... on seperate power supplies.. like the two blinking lights on top, and some of the lights on the very bottom of the box...
 
Adding pictures to help explain.. (to me mostly)

since I m new to navigating my way around pinball machines..

The one picture shows the back box and all the lights are out.. as are the lights for the coin slots, drop targets, and various other play field lights.. the bumper lights do work.

The one picture (#0267) of the board w/ the fuses.. in the middle you can see a RED pan cake type resistor.. I found that one leg is broken away from the board and needs to be re soldered, I hold it against the board and no change.. (maybe not a good connection) this anything to do w/ those lights?

The back of the box I included.. excuse the dumb question.. but I am testing the voltage , or lack of on those lights that are out.. If I hold one probe of the DMM against one side of the light socket, and the other to a ground strap.. I get about 4.75 volts DC (DC is correct right?) If I hold one probe to one connector on a light socket, and the other probe to the opposite light socket connector, I get NO voltage.. Which is the correct way to test?

I checked all the fuses I found under the play field and the one I found attached to the bottom of the play field.. all test good...

I FOUND it !!!


It was something in your advice.. the correct fuse is the lonely one by itself, not on the circuit board..

almost looks like room for two there, but the bottom one is wired direct..

I decided from the diagram I should be testing AC

so I put my probe on the left side of the fuse socket on the yellow wire...

pushed, heard a little sizzle.. and all the lights came on ! :)

must be a bad connection on that fuse holder...

whew... but... the victory is even better now..

I prob should still fix that broken red pan cake resistor huh? :)

tks for the time to give input and positive support...
 
yes, yes I meant that.. thanks for the correction..

and I will do.. I think I can just resolder it... leg just broke, prob from being pushed over..

tks again...
