MEI cashflow bill. was working for a while. on this machine, the main battery seemed to be running low, a new one lasted a week or two. i removed the varta and u16, and put in a new main battery. BV doesnt light up. one slow flashing green led. swapped BV's with another game, and same deal. the other still worked. swapped MPUs, and same deal. still not working, the other works. cash can door switch bypassed and shows closed in test.
cash can opto seems to be good, removing and installing the can causes the BV to cycle. bill acceptor is enabled.
two things i noticed. the first, if i go to bill acceptor test and try to calculate the CRC , it goes into waiting, and finally , no response. on my other game, it calculates in seconds. the other is i get a fair amount of random reel tilts on start up. i did swap the slanted IO card, no help.
swapped mpu's, swapped Bv's, cleaned the edge connectors, did a clear/key, enabled acceptor, and i got nothing.
thanks
