Rittenhouse Service & Repair Forum

I am looking for a wiring diagram for a Rittenhouse, Spartan Electric, Fayettevile NC C8845 unit which is 30 to 35 years old. It seems to be either able to use two D cells or 16V transformer but I am got sure how to wire it up. Any ideas? Thanks.

I have the above mentioned door chime (Rittenhouse door chime model C8536) that does not work correctly. There where some broken wires from the transformer coils that I soldered back on and now it does not work correctly. Do you have a schematic for this unit?
