hi all. we have a barcrest lucky strike (mpu4) which seems to be paying out 103 %. i have bought a switchable percentage key off fleebay and hopefully this will sort this out when i get it.
i read that it should say on the display what percentage it is set to but it does not,
 
in test mode test 7 comes up failed, is this the one for the percentage ?
 
thanks Jeff
