I suspect that your power supply is at fault.
Unplug the unit.
Open the unit and disconnect the internal wiring from the transformer output(The side not connected to the power cord). Be sure to mark the wires with masking tape as you remove them one by one. Insulate the (now open) transformer wires and try the power again. If it trips then you have a transformer problem and it will need to be replaced. If you cant find an OE replacement then continue :
I have no idea what the internal operating voltage of the unit is. If the transformer is not marked and it more than likely is not, you will have to dismantle the transformer and count the amount of times each of the input and output wires go around the core. Then calculate from that what transformer is needed. You will need to know the output(secondary)wire thickness(guage) - this determines the wattage - and the amount of windings. ie 400 primary windings and 100 secondary windings will give an output of 110V/(400/100)=27.5V
If however it turns out not to be the transformer you will need to check deeper into the machine. Start with the 2 motors(fan and drive) and check for short to ground between each of their connecting wires and the motor body.
A transformer looks something like this :

Yours being somewhat older it may not look quite as shiny and would probably have wax paper around the windings.
Refer to diagram : Transformer

Be careful about replacing the transformer. It is used to drive the
motors and control unit at a lower voltage. Not the lamp. The ratings given on the machine
is the input rating and does not relate to the voltage on the machine
side of the transformer. If you're not sure have your electronics supply store check the transformer out for you.

Hmmm, it definitely sounds like an internal wiring issue. I am confused about why the guy won't take it back, I guess because it's beyond the 30 day return period? Did you explain that you are one of our country's finest examples of a citizen and were serving your country? And he wouldn't work with you? Man that's a shame :(, if it were me I'd make sure you were taken care of. Regardless, I personally appreciate your service, so thank you :). However, that's besides the point. The good news is that you are probably still well within the manufacturer's warranty, especially since you just opened it. Please let me know the make and model of the machine in question and I will get you the phone number or who to contact to get a free replacement / repair from the manufacturer. If somehow they won't help you, which I'm sure they will, we can work on figuring out the wiring issue. But chances are it has major issues that may end up costing more to fix than it's worth. Also, if you purchased this machine with a major credit card (not a debit card, but a credit card) it is also probably covered by your credit card companies electronics coverage (that most people don't even know it exists). So basically, we will figure out how to get this thing replaced for you.
So for starters, what kind of machine are we dealing with? At least the manufacturer, if not make and model... whatever you can give me I can work with.
Thanks so much sir,
Tim
No worries, glad to try to help. I see, I was thinking it was a brand new unit, and a fax machine at that! This is definitely more complicated than I expected but will try to help. To be honest your best bet is to contact 3M and request the wiring diagram, they should give it to you without much hassle for sure. Also, I tried pulling up that part # and nothing came up, 888-364-3577 is the number for 3M, just hit 0 when it starts the recording to go to a live person. I don't think it's 24 hours though so you may have to wait til tomorrow. If you want to find the part number off the machine I will keep looking over here. Are you not near the machine now? It should be on some kind of label on the machine. Most of them look like 4 digit part numbers, like 3421 or something like that.
Thanks sir,
Tim
Wow, that is so strange, sorry for doubting you on the model number. There is nothing listing that model number that I can find.... it must be very obscure... for it not to be listed anywhere I can find is very rare. You will want that model number and serial number when you call in to them, so it's good that you found that info.
I will see if I can dig anything else up as well.
Thanks for bearing with me, keep me updated if you feel so inclined :)

Wow, that was fast. Thank you, and yes I mentioned the fact that I was off in Iraq to the guy, didn't really help... but the unit was sold as is, and he stated that it worked for him (even showed me stencils he had made with this unit) Its my fault really, shoulda waited til I returned to purchase.
The reason I'm asking for the tech help is because it is a used 3M Transparency maker. They are hard to find new, and if you find one, can't get them for less than a couple grand. Almost every unit I'v seen for sale is refurbished, and still in the ballpark of $900. I found this one for $500.
I believe the model is 45 FGA. If theres any way to get/purchase a wireing schematic, I can dust off the old multimeter, and see about pinpointing the problem.
I figure there's quite a few things that could be wrong,... for the most part, I'v only witnessed the bulbs, or the belt needing replaced.
I'm not even sure if you have had many requests for this particular piece of equipment. Nowadays they are pretty much solely used for stencils, either tattoo related, or silkscreen.
Like I said, I appreciate any help you can give me.
The only numbers (besides individual markings on the parts inside) are located on a metal plate on the inside of the lid. There is a small box that sais "listed" and the # in the box is 424N. The serial # is 657994, and the model # is 45 FGA. There are more boxes with numbers but they are referring to the volts, amps, and wattage of the bulb. I didn't receive any literature with the unit.
Thank you for the number, I will definately give them a call in the morning.
I will give them a call, and I'll be sure to send you a message with my findings. Thank you for the number, and your assistance thus far. If you do happen to find anything out about the machine, please let me know. By the way, may or may not be helpful, but this model was once referred to as "the secretary". Take care, and thanks again for your time.
Jeremy,
According to the metal plate inside the unit, the machine is 115 V, 60 Hz, 1400 W, and 12.0 A. The Lamp by itself is labled 115 V, 1350 W. Thank you for being so "indepth". I assume the transformer will be the next thing in line, following the safety interlock switch? Thank you again for your time.
