HI GUYS
I HAVE A JPM IMPULSE MACHINE, SOME OF THE BULBS HAVE BLOWN SO I BOUGHT SOME 5MM 12V LIGHTS AND WHEN I FITTED THEM THEY WERE ALL REALLY BRIGHT AND BURNING OUT, ALSO BURNING THE LAMP HOLDER.
CAN ANYONE TELL ME IF I HAVE GOT THE RIGHT BULBS AND SHOULD I HAVE GOT 24V ONES.

THANKS
ROB

12v are the correct bulbs and as the old ones you replaced had possibly blown the same way, the fault will most probably be with the lamp multiplex driver on the main MPU will be shorting and burning them out.Apart from eg. coins on the board causing the short, the multiplex driver will be faulty and you will have to replace the MPU or run it without those bulbs.
