My parents have a Model C8538R Rittenhouse Div. / Spartan Elec. Co. door bell chime and it is not working. The date stamp on the unit says 11/91 which would indicate to me that it was manufac. in 11 of 91. It appears to me as though there is no power to the unit, i have taken the door bell off and touched the wires together and nothing. Can you trouble shoot this unit if i send it to you and what might your advice be to me currently?
Thank You.
