Hi All
Sorted power supply out on my Royal Guard after it was wired the wrong way around.. thx guys.

Problem is I think I've altered something whilst fiddling around? when playing, the playfield lights keep going off and on again?
Would my novice diagnostics be correct to say it could be a dodgy contact on the tilt relay?

Dunno how you guys go on with 20+ to look after, must be a full time occupation.

Thing is I don't know for sure??
I had another issue besides the special problem where the D & E rollover lights wouldn't always go out or flickered so I cleaned and adjusted the contacts on the relays as was mentioned in another thread and it started working fine when I turned it on??

All was fine up to me changing the hot and neutral wires around this morning before I went to work, when I tested it the lights go out as tho it's tilted but game still plays fine.
During gameplay they're on and off everytime you hear a relay pull in on the main reset bank.

Thanks' for the info again lads, I sure do owe you a all pint of your favourite beverage..

Bit more info for you pro's.

Starting from cold no lights on playfield but back box lights are on, ball no.5 has slight glow and last ball in play as a slight glow.. Also doesn't show ball in play whilst lights are in faulty mode.
After about 5 mins lights come on an go off then after around 15 mins they stay on and all's ok?

Fuse holder looks good, I would've thought the same but wondering why no.5 on ball play and last ball in play has a slight glow?
Also match feature numbers have stopped lighting but gives a reply if it matches regardless of bulb lit..

Just been playing for an hour on and off and not a flicker?. But I know when I turn it on tomorrow from cold the fault will return until it warms again?

Any thoughts guys?

Thx guys, will check these possibilities out and report back....

Found the problem.....
When I pushed harder on the 30v hold relay which was already pulled in the lights came on... Quick clean and contact adjustment and all's well..

Still got the problem with the end of game match for credit tho???
I know that if the end of game corresponding reel number matches the random match number it knocks for a credit, problem is the number isn't lighting up on the backbox??

Any pointers on where to look?

Yeah none, when I first got machine they were?
It's giving a replay tho if there is a match but no lights on the 1-9 after the game ends?
Could it be a contact on the game over relay or tilt relay, or a dodgy connection on the Jones plug?

Do you know which relay actuates the random numbers light?

Thanks' DF, will have a look tomorrow, at work at the moment.
