Elye Posted June 18, 2021 Report Share Posted June 18, 2021 My '85 Nissan 720 will not shut off when I turn my key off. Even when I remove the key from the ignition and unplug it still runs. I've changed the ignition even tested what could it be. 1 Quote Link to comment
datzenmike Posted June 18, 2021 Report Share Posted June 18, 2021 Try punctuating your run on sentence to avoid confusion and more questions. Have you replaced the alternator lately? Is there anything you have done to it lately?? When running try unplugging the plastic 2 wire plug from the back of the alternator. Does that shut it off? 1 Quote Link to comment

datzenmike Posted June 18, 2021 Report Share Posted June 18, 2021 You replaced a relay? I would start with that. Unplug it. If engine stops, try replacing this relay with a another or a correct one. 1 Quote Link to comment
Elye Posted June 18, 2021 Author Report Share Posted June 18, 2021 alright ill try that 1 Quote Link to comment
Elye Posted June 19, 2021 Author Report Share Posted June 19, 2021 so it wouldn't shut of so i removed the coil wires so it would die and when i put them back on was wondering if they where on there right and so i changed them around and it shuts off 90% of the time but sometimes doesn't 1 Quote Link to comment
datzenmike Posted June 19, 2021 Report Share Posted June 19, 2021 Lets go back to the beginning. 1/ This was working alright and then all of a sudden it wouldn't turn off??? 2/ when you turn the ignition off and it keeps running can you use your turn signals?and do the dash gauges gas and temperature keep reading? 1 Quote Link to comment
Elye Posted June 19, 2021 Author Report Share Posted June 19, 2021 the turn signals dont work at all and the my gauges work still yes 1 Quote Link to comment
datzenmike Posted June 19, 2021 Report Share Posted June 19, 2021 Have you recently replaced or messed with the ignition switch?? The ignition side of the fuse box, that's the first 5 fuses on the left, are turned on and off with the ignition switch. The first fuse is for the exhaust side coil and the forth fuse is for your gauges and some other things. These are obviously still on when the switch is turned to off. I would say the ignition switch is at fault. 1 Quote Link to comment
Elye Posted June 19, 2021 Author Report Share Posted June 19, 2021 i tested and replaced it before 1 Quote Link to comment
datzenmike Posted June 19, 2021 Report Share Posted June 19, 2021 Engine should shut off when the ignition is disconnected or unplugged. Does it? 1 Quote Link to comment
datzenmike Posted June 19, 2021 Report Share Posted June 19, 2021 Well it should. Battery power gets to the fuse box and the ignition coil(s) through the ignition switch. Where was that relay you replaced???? Try unplugging it and see if that shuts it off. 1 Quote Link to comment
