I've been working on the switch loom, the white plug is done, orange is done, black
is done, but I've hit a snag on the yellow and violet plug, I don't have enough available
connections which presents a problem because I don't have the molex crimps or a molex
removal tool.
I can see now why I had 12v meter alarm when I ran the EG loom with
the RD program card. There are many differences in the loom, far more than I had
imagined. The looms are very different and a certainly not interchangeable without
considerable work.
I can't progress it until I resolve the issue with the crimps
or find some way or reworking an old plug.
After a wasted week messing about crimps and plugs, in total desperation last night
after the second lot of crimps proved unsuccessful, I had no choice but literally
cut up a blue plug in order to remove the crimp and wire in tact. I had tried to
remove the crimp from the plug but it was too damaged to be used again. It's something
I need to resolve for the future, but for now I want to get RD finished.
I managed
to get around 12 wires and crimps in tact from the blue which allowed me to move
on.
Getting closer now, the yellow meter drive plug is done and the violet and black
plugs just need some finally checking.
It so frustrating that the same connections
are wired differently between machines. There is no standard implementation within
the plugs.
Another Sunday night and back to the loom.
I picked up a few more errors that I had made on the loom and I made doubly sure
no 50v found it's way to ground via the switches. [L/O means Lock Out, (magnets)
not low as in switch level low, that was very close, fortunately I didn't believe
my eyes when I read the diagram. (50v to 0v through switch = boom + burning smell)]
Anyway
hit or bust, first power on. 10p coin switch alarm. (test with meter 10p line is
shorted to ground) ummm, I had the spades on the wrong connectors on the 10p coin
switch. (should be normally open, not normally closed) oops!
OK, she runs! No burning, magnets come on and she goes into attract with all looms
connected.
I play in test and all is well. So far so good.
Close door switch and coin...
VTP meter alarm!
Now I was expecting this. I had 12v meter alarm originally and I
wondered whether I had shorted the transistor array which buffer the meters. Anyway,
swap meters for another set and same alarm.
Could be the MPU, but it could also be
the wiring? So I checked the violet plug.
Meter sense is missing. (I got confused
when I did the wiring, black and white wire to black and light grey wire, missed
the connection, no meter sense, so no meter pulse). Connect meter sense on Violet
to Black 11 and power on.
OK, now it boots and crucially it will coin with a 10p (I
was thinking of Steve when I put a token in), that was OK too.
The Mars mech is OK and that coins and gives change.
So, now it's time for a game!
Initial
observations;
The reel bands are not perfect and will need to be re-done.
The wiring is scary and will need a few days to tidy up (I cannot show you a pic of the back of the machine at this stage, it looks like a BT wiring cabinet)
