Re: TECH: System80 Solenoid 5 not firing...still

Hmmmm. Interesting.
BTW, the negative side of the cap is shown on the cap and the PCB is
screened with the "+" symbol.
I'm not positive how your PCBs are mounted. Some games rotated them 90
degrees CW. If yours is mounted like this picture of a Bounty Hunter,
then you were connected correctly.

If you are seing a pulse at pin 2 of Z30, then solenoid 5 should fire,
assuming all downstream parts of the circuit are correct.

When you slipped (don't worry...happens all the time), you effectively
brought pin 2 up to a high signal since pin 3's normal state is high.

This is confusing as shorting pin 3 to pin 2 and having solenoid 5
fire proves all of the circuit from Z30 to the coil.

Let's test all the pins of Z30.
Pin 1 is at the dot on the chip, or if the chip is notched, it will be
the one to the left of the notch. Pins are numbered down the side with
pin 1 on it, around the bottom, and back up the other side (like a
horseshoe pattern).

This is what you should see in attract mode...
1 - H
2 - L
3 - H
4 - L
5 - H
6 - L
7 - L this is the chip ground
8 - don't care (probably not connected)
9 - don't care (probably not connected)
10 - don't care (probably not connected)
11 - don't care (probably not connected)
12 - L
13 - H
14 - H this is the chip 5V supply

Let's see what you get from this test. I'm going to hold off making my
next suggestion as I really don't want to go there just yet.

BTW - Did solenoid 5 =ever= fire as it should, perhaps with the old
driver board? Or, has this always been a problem with both driver
boards?

Yes, there is definitely a high pulse on pin 2 of Z30 when in test
mode, and Low when in attract or otherwise.

I connected the + to the left of the cap and - to the right.

I slipped and accidentally shorted pin 3 to pin 2 with the probe and
solenoid 5 jumped.
