New Life Games Tech Forums

Hi guy first post but it wont be the last now that i have the slot bug!

i use to be an electronics tech so i was pretty stoked when i got a mk4 (broken) for a case of beer running white tiger.

iv fixed everything to the point that the power supply trips the mains circuit breaker after it has warmed up about 5 minuets then keeps tripping after reset. if i let it cool down it will do the same again trip the breaker after 5 minuets. :103-

so my question is where would i start looking on the power supply and where would i get a circuit diagram?

its been 10yrs since i have sunk my teeth into switch modes and for the life of me i cant recall seeing this fault. :103-

i have found the service manual but it doesn't have a circuit diagram for the power supply.

any help would be great,

thanks chemstar

Hi guys I found some info here http://newlifegames.net/nlg/index.php?topic=200.msg1760#msg1760

Also I forgot to mention all voltages are correct and the machine works fine until it warms up

hi guys well it is now fixed, the screws holding the first filter were loose from the case and the blue and brown wires on the input socket were the wrong way around  :103- dont know how that happened and now it wont trip the mains switch

hope this helps someone
