inkcraft machine is dead

[iLL]

okay, i got new coils with the compacitor and i have voltage when i set it up for operation.i know this because

first i tested voltage from the clip-cord attached to the back standoff and the top of the frame, it would read no voltage

second i tapped the armature bar on the front coil. when the armature bar touches the coil i have voltage.

so that rules out grounding right?

i just want to hear the buzz!!! its been 9 days!!!

i'v had to reschedule 7 apointments.. i'd buy another machine but its to close to x-mas. i cant justify it with the wife lol

[voodoo]

did u ohm out the coils/machine to see if u have break?

[iLL]

go into alittle more depth voodoo, i just figured out how to get a reading out of the multimeter, let me know how you think i should check it out :D

[voodoo]

an ohm reading is the amount of resistance. so put the meter on ohms and touch the top and bottom binding posts. u should have some type of # being read on it.if not u have an open circuit.if u touch one of them then the frame and get a number its shorted out someplace.do u have a fuse test selection on it?if it does switch to it and it sould make a noise that u can hear.(instead of a number)wich makes it easier to check!

[iLL]

alright, i set the meter to the one that makes noise. here are the locations i tested for a short

top binding post and bottom binding post. the meter buzzes and reads a resistance of 002.
top binding post to the bottom of the frame near the coils. same result.
bottom binding post to the top of the frame, near the armature bar. same result.
bottom binding post to the tops of the coils, same result, exept when i push down the armature bar on the front coil so it no longer touches the top contact screw
top binding post to the top of the front coil, same result, unless i push down the armature so it no longer touches the top contact screw.

can you think of anywhere else i could check for a short?

iv been trying to get some diagrams of machine parts off the web with no luck, just to make sure i didnt drop a plastic insolator or washer, please correct me if im wrong but the only place on the machine where the plastic washers go are on the screws conected to the top and bottom binding posts. if you have a link to a good website with machine diagrams of all the parts let me know too :D

[JOCK]

JJB gave me the link to this web site it is very good, should be what you are looking for ,www.machinegunmagazine , hope this helps :D

[iLL]

thanks, that is an amazing website, and from the diagrams im now 100% sure i have all the parts. but the machine still wont buzz.

[voodoo]

eikon has one y can down load.same people as machinegunmag!
u should not have a reading from the posts to the frame it self as they should be insulated!

[iLL]

the only time i get a resistance out of the meter while it is attached to the binding bar and the frame is when the front spring touches the top contact screw. this is because there is no insulation connecting the armature to the frame... thats where i thought i had the problem but there are no diagrams i'v seen that show insulation on the screw connecting the armature to the frame

[DANTHEMAN]

is the machinebrass or aluminium, you ll need a yolk if it is., check the solder lug conectionsand makesure that theyres hardly any tension on the back sring, make sure nine of the coil wire is showing through the insulation wire ir touching the frame anywhere,make surethe wires are connected tothe right places not shortingit out or something,what are you usng for shims? does the power supply work properly,try another clipcord,mabe eve just a speakerwire to see if itlltake powewr? show us a photo from all angles apart and put together.

brass machine, from www.inkcraft.com they only have 1. this is an almost perfict diagram http://www.machinegunmagazine.com/MGM_HTML/MachineParts/machine_parts.html
i think that i might have found the cause. with my digital multimeter setup on the (the horseshoe) setting :lol: at 2k
at 6volts, it reads .726
at 7.5volts, it reads .758
at 12volts, it reads .815
im not sure if that means im getting less then 1 volt from the power supply or if getting 7.26 volts yuh know?

another detail you might want to know is im testing it from the end of the clip cord that attaches to the machine. i only get these reads when i press the footswitch. so atleast i know my lines good

[voodoo]

the more current will equal more resistance. so they look correct.
the numbers it shows r the ohms... :wink:
