electrical problem

[Papasmurf]

Hello I'm having a problem with my 78 280z where it refuses to start. I believe it to be a problem with an electrical relay. I have tested the battery and the starter and both are good. the connections all seem to be good. I try to start the vehicle and find all that happens is the main relay under the passengers side dash starts clicking like crazy it has these markings "25230-89958 MR 3S-561 jideco japan" I also hear a relay clicking under the black box where the fuseable links originally were, I have since replaced those links with fuses, I have also replaced my ignition with a push button set up. I have managed to make the vehicle start by bridging the poles on the starter however it's a pain in the arse to have to do that every time I want to start the car.. does anyone have any suggestions?
