Solved: cold injector now working/ but unsure about my solution Posted by 2nd Owner [Email] (#70) [Profile/Gallery] (more from 2nd Owner) on Tue, 8 Dec 2020 18:15:02 In Reply to: Thermo-time switch testing help, 2nd Owner [Profile/Gallery] , Mon, 7 Dec 2020 12:59:19 Members do not see ads below this line. - Help Keep This Site Online - Signup |
This morning I found another section of the Bentley with ohms testing numbers to confirm my TTS was good.
So I moved my attention to the starter solenoid its wiring. I noticed that the terminal 50 spade connector had clearly been grounding out on the heat shield. I tested the terminal and it had no voltage during cranking. I then jumped 12v to the wire itself and the cold injector squirted fine.
Instead of buying a new solenoid I decided to move the 50 wire connector to the empty spade next to the ignition switch connection spot on the solenoid. They are clearly bridged as one piece of copper, so it now gets 12v while the key is rotated to cranking, and the car fired right up.
Here is my big question because I can find no diagram/schematic googling around to tell me what that empty connector is normally for. Also, I don't completely know for sure but I assume the original location for that 50 wire must tap into the battery feed directly when the solenoid activates // so do you think instead tapping into the voltage of the ignition switch directly to fire that injector will be a problem? I can't imagine much amp demand by the injector. Anyone have an opinion if I can leave it set up this way? I only see two other spots that terminal 50 shows up during cranking / at the time relay and the hot start pulse relay - but I don't know what happens with it there.
overall, I hope this solves a bunch of little oddities. I wonder what mischief was happening when it was totally grounded out during running.
