JimmyS Posted January 23, 2020 Share Posted January 23, 2020 I found this old cutout in a drawer in my grandpa’s shop, I don’t think it was ever used, looks NOS. It has 3 terminals, I believe the fused terminal goes to the generator (seems odd?) H to the battery? And S to? The cutout on my 32 Chrysler only has one to generator and one to the ammeter (battery) any thoughts? Link to comment Share on other sites More sharing options...
Guest Posted January 23, 2020 Share Posted January 23, 2020 It looks more like a fused relay than a cut out? Link to comment Share on other sites More sharing options...
TerryB Posted January 23, 2020 Share Posted January 23, 2020 There were some cut outs that used a fuse in the field circuit to protect the generator. The S and H connections are a little confusing. Link to comment Share on other sites More sharing options...
Graham Man Posted January 24, 2020 Share Posted January 24, 2020 Could be a headlight relay this is a Delco unit Link to comment Share on other sites More sharing options...
Mikefit Posted January 25, 2020 Share Posted January 25, 2020 Horn relay. H= horn. S= switch. ?????? Link to comment Share on other sites More sharing options...
Frank DuVal Posted January 25, 2020 Share Posted January 25, 2020 That makes sense. Looking close at the picture, hot goes to screw by fuse, so current goes through fuse (conventional current flow, physicists be quiet) to solenoid core (yoke), then through braid to "armature" (in relay speak that is the movable contact) where it waits for the contact to close then the current flows to the H terminal. The solenoid coil connects to the yoke/core to get a hot, then the other end of the solenoid winding can be clearly seen connected to the S terminal, where a switch connected to ground would energize the solenoid coil, making the H terminal hot. You have found a Horn relay. Link to comment Share on other sites More sharing options...
