And don't forget those of us on dialup ...

Mom?  Is that you?

depending on the credit board you will need +12volts and common,at the moment it sounds like you have coin signal and coin common only,i guess you are using a electronic coin mech like a c120 or sr3
if you look at your credit board it should have written next to the input plugs what you need e.g +12(+v, com(grnd),coin,lamp,coin counter(meter)
what credit board is it?

[smythe]

coin mech is me126
credit board is philip shefras

the above are connected together with a ribbon connector
ill try and get a picture ...
when u say 12+ ect where do i get this power from?

cheers

power supply or the jamma connector,i am very familiar with both the mars mech and the pre deith leisure credit board

[smythe]

heres the connetors for credit board

con2 - 100/50/20/10 (no wires in these)
con3 - com/no/mtr/lamp (meter wire in mtr)
con 5 - 21/21/21/no (other meter wire in 1st 21)
a quick connect different to above  - coin 1 & gnd connected to this

there are also 2 set of dips

any idea where i put +12v & com

cheers
p.s. i have one of those hanterex newer type power supply

how many pins on the quick connect?and what is the colour of the board?

[smythe]

hi the quick connect is a plug type connector when the plugs removed
theres one pin then one missing then four together so 5 pins but a 6 pin plug..

at 1st glance the board looks green but when theres a bit of light behind it it looks blue....

cheers in advance

how good are you with a multimeter?
do the quickfit connector pins have anything written on the board,use a flashlight

[smythe]

nothing written on the board only jfmamjjasond think thats just the months of the year..
ive turn the plug round and now the credit button on the board works (some gimp put the plug on back to front)
does this mean the board now has some kind of power?

p.s. the coin mech dont work still (has a sticker saying new 50p) thats what ive been trying

cheers

for you to get credit from the credit button on the credit board  must mean you have power,clean the coin mech and test with a 20p coin
you can meter voltages on the coin mech ribbon cable to see if you have power to the coin mech if you have a multimeter,you could have a faulty coin mech
you must have at least 3 wires going to the credit board

[smythe]

hi theres 4 going to the cb
2 are black with white bits
one orange with white bits
one green with white/orange bits

think ive blown a fuse while i was checking couple of wires must have touched as the cb dont work also the sound no longer works....

boo hoo

i might just buy a new mech from e-bay there not mega expensive

[grantspain]

if you lost sound and credit board you have blown a fuse on the +12volt line somewhere

[smythe]

yeh ill check the fuses tommorow i think ive got another mech somewhere i had a c220 but cant remember where i put it...
ill try that in morning
any1 any ideas where i could host some picks of the cb?
(free)
cheers to gs for you knowledge up to now
