Been lurking the forums for a long time now and figured it was time to join officially.
I have a 1981 HJ47 RHD, originally from Australia, and have the dreaded "click" but nothing more when trying to glow or start. I pulled the glow plug relay and tested with a multimeter (relay part number is the 28610-46030) -- I'm getting +12V on the B terminal of the relay, and nothing on the G terminal when turning the key to glow or start. I can occasionally get a reading of ~+10.5V on the G terminal when the relay is intermittently functioning, but it's left me high and dry in a parking lot before and I need it to be reliable while I'm working on our other vehicles.
That said, I've searched thick and thin, and learned a ton of useful info regarding the glow plug wiring (and some of the erroneous material in the FSM), but haven't seen much in the way of retrofitting an aftermarket glow plug / starter relay into the setup / wiring on my rig. I picked up a glow plug relay that looks to be a reasonable replacement, pic below. I wanted to consult ya'll regarding the wiring before proceeding.
My plan was to run the original wire from the battery feed "B" terminal of the stock relay to the left-hand post in the pic above, and the glow feed "G" terminal of the stock relay to the right-hand post, but I'm not sure how to wire the front two terminals. The front terminals on the aftermarket relay are marked "S" and "I", I took that to mean "start" and "ignition", but I'm not sure where to wire in the glow / start wires of the ignition switch. My rig has an EDIC motor, and I've been using the diagram below as a reference for my wiring (shout out to lostmarbles for his excellent work here, credit goes to him for the diagram). Any help would be appreciated.
Thanks!
