Roz Posted May 18, 2015 Report Share Posted May 18, 2015 I've got a 72 510 that I've just gotten running with a KA24e. Everytime I hook up the battery, the relay in front of the passenger strut tower clicks on, regardless of the key position. I think it is the starter relay. The car starts and charges fine. Is this normal? Quote Link to comment
datzenmike Posted May 18, 2015 Report Share Posted May 18, 2015 Is it about the size as your fist? If so that is the external regulator for the alternator. It should not click, in fact no relay should click just from connecting the battery. If left sitting the battery will slowly drain. Do you know what alternator is in the car? Is it the one that came with the KA engine? If so it is an internally regulated and should not be run with the external regulator also connected.. Quote Link to comment
Roz Posted May 18, 2015 Author Report Share Posted May 18, 2015 I guess I should have stated that. The alternator is the KA unit, and the voltage regulator is gone, with the wires jumpered. The wires to the relay are yellow, blue, black, and white w/ blue Quote Link to comment
datzenmike Posted May 18, 2015 Report Share Posted May 18, 2015 Yes, this is the electric choke heater relay and when converting to internal regulated alternator it will permanently wire the relay ON even with the key OFF. Long story short... disconnect the relay. You don't need a choke or choke relay on an EFI KA swap. Quote Link to comment
Roz Posted May 18, 2015 Author Report Share Posted May 18, 2015 Beautiful, thank you. The 510 gets an exhaust today. My neighbors approve. Quote Link to comment
datzenmike Posted May 18, 2015 Report Share Posted May 18, 2015 I like easy fixes. Quote Link to comment
Laecaon Posted May 18, 2015 Report Share Posted May 18, 2015 I wonder where they put that relay on Auto cars, as that spot is for the starter inhibitor relay and the two screws to the left in the picture are for the reverse light relay. Quote Link to comment
