greyhound crane claw problem

i believe it was a black wire coming from the right bumper and tension switches ,going to the plate drop switch

That would make sense then.
Sounds like it was the ground for those two switches, which basically would make them NOT work.
 

Got a pic of exactly what part is clicking ?

so when i fire up the machine it flashes 02 06 1987,  then the coin mech clicks the light flashes on then goes right off  and continues in that fashion

That is the lock-out coil. It is to prevent people from losing money in a machine that is turned off. (won't accept coins)
It should click one time when the machine is turned on and stay on in order to "unlock" the coin mech.

Is the WHOLE machine resetting ? To where it flashes the date code and all that over and over ?

yea pretty much we got it to stay on and add credits by fiddling with wires tryin to find breaks or anything

[Kevin Mullins]

Measure all the voltages on the switching power supply. Make sure they closely match what they are marked. (+5vDC, +12vDC, etc, etc)

Re-seat all your wiring harness connections and the ribbon cables.

alrighty i'll start looking at that stuff im thinkin its a short or loose or broken wire

i think that connection was loose i took it off and popped it back on and its been on for like 20-25 credits played and no resets

[Kevin Mullins]

Yeah, that style edge harness can get a bit weak over the years. Or it just may have been a bit "dirty".

So is the machine running 100% now ?
Dropping fine?
Stopping the motor when it goes right ?

yessir i have had it on all day and the credits stay added no resetting all the bump stops  work good
now i just gotta get new locks I'm thinking about getting blacklights for the tubes  in the main compartment replacing the sides with color plexiglass getting some colored gravel for the bottom

[Kevin Mullins]

Awesome !! 
Always good to hear when things come together and start working.

Once you play with it some... if you find you need to adjust the claw strength there is a whole little procedure for it.
But most of the time you can fiddle with the two potentiometers on the claws power board and figure it out.

[thelosthero]

cool yea  i gotta check into that seems like it grabs pretty hard
   thanks for all the help i'll have to post up some pics as i get the work done 

[thelosthero]

swapped out the white lights in the top for blacklight tubes and got a lock installed i gotta take a few back and get some longer ones today so i can finish installing them also replaced some of the lights in the top  compartment with the sign over it
