New flasher unit

Been tinkering with my turn signals lately. Flashed too quick sometimes on right side. And a sporadic indicator at best. Took it apart, cleaned contacts and made sure of ground, made new indicator bezel. Wound up with no indicator, but turn lamps work great now. Indicator wired to flasher, so I bought a new one. Electronic, nowadays. No flash anywhere. What gives? Hope it ain't back inside that little box! Too tiny for my fat clumsy fingers!
