New replacement half-wave rectifier for 1980 and 1981 Honda CT110s.
This unit replaces Honda part numbers 31700-124-003 & 31700-124-008

Please verify that the unit you are replacing looks like this one!  
This is for 1 rectifier only. 
I also sell 4 wire rectifiers for the 1982 and later CT110s, check my other listings for those. 

Thanks for looking!
