If you have no AC power at your main switch, then the problem must somewhere between the switch and the power distribution box. Check your breaker on top of the power distribution box. Be sure you have a good power cord and it is well seated.

Is my assumption correct that I should have the voltage at the power switch from my PDB? The only things that I have removed is the reels and hopper.

You are correct. As long as the machine is plugged in there should be power to that switch. There should also be power to that 120vac service outlet on the power distribution box. If there is no power, the most probable cause is the breaker in the distribution box.

I don’t remember seeing a breaker. The only thing i recall is the relay on top of the PDB. I read through that with a multimeter and it appears the relay is good but I’ll double check. Is that a resettable breaker and where is it in the box?

dailey · « **Reply #24 on:** March 08, 2022, 12:31:26 PM »

Power distribution boxes all have either a fuse or a resettable breaker. Note that if the breaker is closed (ok) there will be power present at the 120vac utility outlet on the front of the PDB. Testing the outlet for power is easier than going into the box.

Kooper06 · « **Reply #25 on:** March 09, 2022, 06:42:05 AM »

I did both, The outlet has power and I pulled the PDB and rang resistance through the circuit breaker and also had the panel off and shot voltage at the circuit breaker which read 61vac going in and out everything so far shows voltage in the PDB is good.

I’m assuming the Filter transforms the 120vac to a 60vac circuit.

So the power at this point should go to the on off switch correct? Is there anything that would prevent that?

I have disconnect several components as suggested earlier for a possible short and have the same results.

Still no power! I have recently tried the following:

I discounted the the Florescent light ballast looking for a possible short and with no luck.

I reconnected the ballast and then disconnected all of the plugs off of the backplane/PDB hoping the Florescent lights would come on and still nothing.

I went to the downloads to try and find a Power Schematic and was unable to find one. Does anyone have a power schematic?

There are 3 ballasts, one for each tube.

dailey · « **Reply #28 on:** March 10, 2022, 07:40:07 PM »

In answer to your previous message, the filter does not transform 120vac to 60vac. If you are measuring 60vac then you have serious problems or you need a lesson on how to use a multimeter. If your machine is plugged into 120vac, there should be 120vac going through that breaker.

Check your power cord. Do you have 120vac going into the machine?

(Note when measuring VAC, always measure across hot and neutral. Not hot to ground.)

Great Evening to You. When You tried the board/power supply from the good machine and it did nothing, Did You try the board out of the dead machine into the working machine and see if they fire up? For Now Leave the TITO board totally out of the troubleshooting equation.

Kooper06 · « **Reply #30 on:** March 11, 2022, 05:28:50 AM »

I just took the board from the bad machine and put it into the known good machine and the board/machine powered up like normal.

Kooper06 · « **Reply #31 on:** March 11, 2022, 09:57:51 AM »

Also when I swapped power supplies & PDB I left the PS from the good machine in the bad and put the PS from the bad to the good one it worked as advertised.

Keep swapping one part at a time until you single out the problem part.

You disconnected everything from the backplane but the power plug and still no lights? Did you pull out the mpu as well while everything was unplugged. Did you also check the fuses on the backplane (if you have a 1270 mpu). If everything was unplugged but the power plug, then I would carefully examine the power plug harness for pinched or exposed wires.

Kooper06 · « **Reply #34 on:** March 12, 2022, 04:58:25 PM »

Hey Rick we’ve got progress….. Like you have said in a previous statement that I need to isolate the source that causing this so I went back to disconnecting components and disconnect the upper feed through harness 60783900 and everything powered up as normal except for all the components that are fed from that harness which I believe is the printer, speakers, lights,etc. Now I have to figure out whether its one of the panels or the harness. I would its the one panel that this plug goes to.

rickhunter · « **Reply #35 on:** March 12, 2022, 05:53:00 PM »

That's the netplex distribution board. They are easy and cheap to find if you need a replacement. Do you power up if you just leave the harness that comes from the bottom, and everything else connected to that board out?

Sunrise Side · « **Reply #36 on:** March 13, 2022, 05:43:20 AM »

Might be a screw or nut behind that board causing a short. Take the board off the mount and check it.

Kooper06 · « **Reply #37 on:** March 13, 2022, 05:54:58 AM »

Yes everything powers up with that harness plugged into the bottom and just the plug going into the Netplex distribution board disconnected except for the items that are plugged into the board which I assume is only the ballast, printer and overhead light. I’m going to disconnect the other plugs and try and isolate it down to either the board or one of the items going to the board.

Kooper06 · « **Reply #38 on:** March 13, 2022, 10:58:04 AM »

So I’ve got it down to either the board or the upper cabinet fan. I connected everything back up one at a time and when I connected the fan itself I duplicated my original problem. I’ll order both and replace one at a time.

Notice that you can connect the 2-pin fan Molex into another 2-pin header on the distribution board?

They are all the same voltage...this will help you pinpoint if the circuit board has a burned out trace.

However, if after unplugging & removing your fan and you find the fan blades have a lot of resistance when trying to turn them by fingers, then you know the bearings on the two ends of the fan shaft in the motor area are shot.

That distribution circuit is held onto the rear wall of the topbox by only 4 small metric screws.

Why not pull the connected Molex connectors off of it, remove the board , turn it around, and see

if there are burned out traces on it?

Give it a thorough inspection. Check out the traces for continuity with a multimeter.

In fact, I suggest that every slot owner learn how to use a multimeter.
