HI Jeff, Welcome to pinside!!
Does the 6 Point Score (G) release early when this happens?

Jeff,
Don’t bother your tech, grind through this Howard will get you there and you’ll be better for it!

Does it work differently when the points score correctly compared to when they don't?

There are 3 relays involved:
The 6 Point Score (G) relay
The G Relay Delay (BB) relay
The BB Relay Delay (H) relay

When that G-relay fires, there's a contact that will make the score motor turn. In the case for touch down score, the g relay firing will make the motor spin I believe a full turn and half which In theory on the score motor the contact responsible for firing 1000point relay will open and close 6times, each time scoring 1000points x 6. If I were you I would first look at 1000point relay, even though I believe the problem is a gap issue with on of the contacts perhaps being a bit to gappy. Because you are usually scoring 3 pulses, sometimes 4 pulses and on occasion the full 6 pulses. Anyways on 1000 point relay inspect wire gr-wh-red make sure it's clean could give a swipe with business card and its gapped nicely.

Secondly on score motor inspect the gap I can't see the first set of schematics(blurry) but trace g relay into score motor contact. On schematics it's near the top index 2-E. I'm assuming it's score motor bank#1
Please take another pics of upper schematics
Motor1a (bottom stack) or-wh-red see the gap clearance on this one, when the motor turns, the pulses come fast, check and make sure it's nicely gapped, clean contacts

I will be back online tomorrow afternoon ... Goodnight

I made a typo, g relay when fired, makes the score motor spin. Looks like a full spin which creates 6 pulses. The leaf on score motor that is responsible for 6pulses is not making correct contact all 6 times. It's usually on motor bank#1. Evidence is you get mostly 3 pulses, at times 4, rarely the correct 6. There's a gap a bit to wide in my opinion on score motor, or dirty contact in score motor
I still like to see the upper schematics as mentioned previous post.
I would still check 1000point relay gr-wh-red wire and leaf gap, clean contact
Score motor gap on 1a(bottom stack) wire
Or-wh-red. Check leaf gap. Turn motor manually, very slow and see if the leafs open and close at every pulse. I like to trace on schematics G-relay at the top part of schematics, its blurry. Wherever it crosses into score motor, I like to inspect and see those leaf gaps and contacts

Goodnight.

If you have owners manual, it should have a description on every score motor stack and its function. Yours is score control stack most likely on score motor bank#1.

This is first game I have seen with "relay delay relays". I'm working on a Gottlieb big hit currently, same kind of concept I guess, I don't have relay delay relays.

On big hit, score control as per your pro football schematics is similar on motor 1a(bottom) on big hit, there's 3 leaf contact point on section a.
and scoring being the middle of the 3 leafs Its a hard one to trouble shoot, being at the bottom. Hard to see or peak.

Did you clean and gap (edit: adjust) the normally closed 2C switch on the score motor that holds in the BB relay? It looks like you are scoring the first 3 but missing the later points/score. That normally closed 2C switch holds in the BB relay when the H relay energizes.

Edit: I should have said "adjust" not "gap" a normally closed switch. It could be gapped when you manually advance the score motor so the switch is in its maximum open position. At the score motor resting positions this normally closed switch is closed!

Here is 2C in the schematic.

Hopefully you get that sorted out. I'm having issues with big hit, I started a thread and hopefully someone leads me to the right path

Some parts of the schematic are blurry.
Can you repost locations 2E-3E for G & H relays.
And 11E-13E for motor run switch letters and 6 score reel drum units.

How did you end up making out with pro football?
