I used a back probe/t pin to get my 9v reading that should be the same if not better reading no?

Got some more testing done today and I found that to my starter I do have 12 volts going to it and at my red/black wiring from the key ignition I have 9 volts when trying to turn over is that a sign of bad signal wire connection should it be 12v?

Got it ok well mine wouldn’t have the best luck starting up rn with a push sadly as it’s like 20 degrees where I’m at currently but after I see if my power wire to the starter is getting its correct amount of voltage I may just do that suggestion you had and see if that can fix my issue

That build is insane and I love it and thanks for letting me know I’ll have to try that if I can’t get it to work I got home late and with cold weather all I could figure was that my battery is good as I tested it with a battery tester and had 545 CCA and my power wire to the starter doesn’t have an open or high resistance, I’m still gonna check for when I crank it how much voltage is it drawing and go from their but definitely a option I will do if I can’t figure it out and how often do you normally gotta use it?

Got it ok well thank you again I’ll look more into it tomorrow

Alright sounds good do you know of any manuals that give wiring diagrams for 720s also?

Got it alright and how can I test for a weak signal from the ignition switch or fix it?

I’ll have to try that tomorrow then thanks for letting me know so positive to the starter positive stud and ground to bell housing should bypass the ground and positive wiring yeah?

I have battery that’s at about 600 CCA and I tried a jump pack as well and as far as my connections for the positive and negative theirs no corrosion on the battery side or leading to the starter

I have a 1982 Datsun 720 with the SD22 and a couple nights ago I had changed out the ignition lock with a 1980 Datsun 720 I have for parts I made sure it worked that night and it did crank over just fine after switching it over, the day after I tired to get it started and all I hear is a thunk from the starter pushing out to engage but doesn’t spin, I checked to make sure the motor didn’t seize somehow and that’s not the issue either I even put the old ignition lock back in and had the same issue, i then just bought a hitachi starter motor off of rock auto to see if that fixed the issue which it didn’t it did the same thing, i even tired pulling the starter out and had it all hooked up and it would kick out but not turn over but did work at an oreillys when hooked up with their machine, has anyone ran into an issue like this? Or is their some sort of reprogram I don’t know about with these old trucks you need to do for new ignition locks or got an idea of what to test wiring wise and see what my issue is?

Just bought a 1982 720 diesel and it doesn’t have a key but can start and with a screwdriver and the issue I’ve had is that when I turn to key the off position it doesn’t shut off and It I had been using the choke it has which I’m also not sure is original or some aftermarket stuff but that doesn’t shut it off either not sure where to start on making so I can shut it off if anyone got an ideas I’d appreciate it
