You can buy the schematic from Pinball Resource.

Nooooo!!!

I'm not certain but I believe the change relay operates an alternating feature. Like an outlane or standup target that will light alternately. Often times these coils get toasty as they are in constant on/off operation.

I'm not the best with a schematic or I'd offer more assistance. I prefer the shotgun approach (inspect, clean adjust everything) and only use them as a last resort. I know Dirt clued you in on this game. Maybe he'd be of some assistance. He has helped me a few times if I have a schematic handy. He's mostly a Gottlieb guy but he's a pretty sharp trouble shooter across the board.

You can send the ashes to me.

Start checking resistance of bell and score reel and relay coils to make sure none are shorted as that will cause an arc across the relay to make it stick. Also make sure no playfield switches are stuck on.

Also Gottlieb score reels of this era are almost identical to the ones Williams used and so is the principal of how they work. If you see any coils with dark or black wrappers there is a good possibility that the windings are shorted to less resistance inside.

Is there a stuck scoring switch on the playfield? If you had a stuck switch on the playfield, then either the 1 point relay, 10 point relay, or 100 point relay would also be stuck "ON" which in turn would lock on the bell coil and score reel coils.

yup, what Ken and o-din said.
if you got a coil lockin on, look for the eos switch on the score reel, thats what unlocks the score relays,and bells...usually

There is a normal reset relay in the backbox that works all the score reels that is triggered by a switch on the score motor. Once they are all reset, each reel has a switch that opens to stop the cycle. There is also a reset relay in the lower cabinet that stays engaged until the cycle is complete.

There should be a relay that pulls in at the start of the game to reset the reels. It will be in the head. Test it manually to see what happens. Maybe that relay has a bad coil?

Hi Wickerman2
I do not have the pin - I do not have the schema. I look in the schema of "Four Roses": http://www.ipdb.org/machine.cgi?id=938 -> Score-Drums are at F/G-5-6 - when You start a new game: Will be operated through "Switch on pulling Score-Reset-Relay". Score-Reset-Relay is at schema-G-3 - operated through "Switch on pulling Reset-Relay" - this coil is drawn at schema-G-3 - operated by pulling Coin-Relay. Want to investigate on these Relays (pulling ?) and investigate on switches mounted (clean ?) ?
Greetings Rolf

I would clean/adjust first row of Motor switches. Then check for a broken EOS on pop bumpers.Then look for broken wires/bad solder joints at score reels. Then turn the lights out and manually activate each score reel from relay with a wood stick and watch for blue arcs.Then look for stuck switches on coin door.

I have seen missing contacts on step units, thats prob normal. looks funky tho.
it looks like all the braided connect wires are missing from shoes...
prob on under side of that disk?
yep, prob a score motor switch that starts the reset.

Have you cleaned and checked the switch stack on the impulse cam of the score motor?

Once you have the schematic you can use a jumper cable and work backwards switch by switch to find out where the issue is. That is, first jumper straight to the coil lug and ensure the coil fires. Then move a switch back based on the schematic and repeat until you find the break.

Here is the fragment of the schematic from Four Roses showing how the score reset relay energizes:

score_reset_relay_(resized).png

In order to energize it is:

- pulsed by the score motor
- goes through a normally closed switch on the coin relay
- goes through a closed switch on the reset relay (reset relay must be energized)

So it should be pretty straightforward to get the score reset relay to energize (it should be energizing on/off as the score motor pulse occurs).

This is assuming that your set-up is the same as Four Roses. I didn't see any make/break switches on the coin relay in the Four Roses schematic 'though I might have missed seeing it.

Maybe attach a photo of the switch stack on your coin relay?

clean and adjustthose switches real good, may be it...

Once you get your schematic you could post relevant bits. I don't think the coin relay should be pulsing during reset though! I'll watch my Heat Wave reset tonight & see the behaviour.

Can you add one more pic? The score motor....

I'll analyze it tonight. It does seem that the make/break on the coin relay is critical in energizing the score reset relay.

Yes indeed.

coin relay contacts, game relay contacts, and that "0" at o r. p. s. u. switch
thats about all there is.

thats the one lookin like it needs some tlc.

Hi Wickerman2
Your post-45 "If all three of those (blades ?) are engaged ...", hmm, it is a Make-and-BRAKE-Switch. When the relay is activated -> middle blade starts moving -> middle-blade LOOSES CONTACT TO Outer-Blade-1 -> middle-blade moves on -> starts having contact with / to Outer-Blade-2. Greetings Rolf
