Maynardb 11 #1 Posted Tuesday at 01:19 PM Hi I have what I believe is a 401 with a Lauson 5.5 hp motor. It has the internal alternator coils and 2 diode setup for charging. I believe it’s a Wico unit. My question is does anyone know what the dc resistance of each coil is supposed to be? At around 2000-2500 rpm, I’m reading about 4 volts ac with the diodes removed, yet the information I have says it should be more. I’m guessing that maybe the tie to ground on the coils might not be good or the coils are bad. I’d appreciate any info thx 1 Share this post Link to post Share on other sites
