Dieselman966 D Anyone on here that runs a NH 1530? I'm buying a 1999 model 1530. Doesn't currently run. It turns over but and makes some smoke but it wont pop off. Tge glow plugs are not getting power when the key is turned on with temps in the mid *40. Are there any common issues with these engines? Thanks for the help. #1 · Oct 16, 2020 Anyone on here that runs a NH 1530? I'm buying a 1999 model 1530. Doesn't currently run. It turns over but and makes some smoke but it wont pop off.

Sort by Oldest first Oldest first Newest first Most reactions #2 · Oct 16, 2020 Howdy Dieselman, welcome to the forum. There is a glow plug power relay and a glow plug timer relay that are common problems. Shibaura engines require glow plugs to start, even in warm weather. After you get the glow plugs working, if it won't start check the fuel cutoff solenoid on the injection pump. If it is producing white smoke when cranking, you are getting fuel to the injection pump. #3 · Oct 16, 2020 Am I correct in assuming that the glow plug timer and relay are probably under the dash? I haven't picked up the tractor yet otherwise I would go poke around. And the fuel cut off solenoid is right on the injector pump correct? #4 · Oct 16, 2020 The fuel cutoff solenoid is right on the injector pump. I do not know where the relays are #5 · Oct 19, 2020 (Edited) Well I got the tractor home today. It cranks over pretty good and produces some smoke while cranking. The glow plugs definitely dont work so I'll have to figure out the relay and timer issue. When bleeding the fuel lines I dont get much fuel out of the injector lines. So I'm leaning towards the fuel shut off solenoid being stuck.

#6 · Oct 20, 2020 So I broke down and bought the repair manual for my 1530. Glad did. There is no replay for the glow plugs on the 1530. Power comes straight from the ignition switch when between the run and start position. I removed the fuel shut off solenoid tonight and found that that is working. I seem to have more smoke coming out of the exhaust now, but I noticed there is also some coming from the crankcase. I'm guessing this is caused by a blown head gasket or bad rings. I hoping it's just a bad head gasket. #7 · Nov 27, 2023 So are the glowplugs supposed to come on while the engine is cranking rather than heating up on a timer first? I have the same tractor and I'm wondering how it's supposed to work. My glowplug light comes on no matter what when I turn the key all the way to the start position, no matter if the engine is cranking or not (i.e. if the neutral safety switch is engaged). I think my glowplugs are very weak. So I have to put the tractor in gear to activate the neutral safety and turn the key to activate the glowplugs manually for about 30-40 seconds without the engine cranking. Then I put it in neutral to deactivate the safety switch and let the engine crank. It won't start at all if I don't do this, so I know the glowplugs are activating somewhat with this method. It's been like this since I got it so I don't know how the glowplug system is supposed to work on this tractor. If you could tell me that would be greatly appreciated. 0 Reply #8 · Mar 9, 2024 There's a position on the ignition where you can activate the glow plugs before cranking the engine. If you turn the key just past the accessories position (but not far enough to trigger the starter), you'll see the glow plug light come on -- hold the key there for 6-8 seconds (when the weather is warm, longer if cold) before cranking. Note that the glow plug indicator light on the dashboard goes out after a few seconds but the glow plugs themselves stay on as long you hold the ignition in that position. #9 · Jun 17, 2024 I’m trying to troubleshoot my 1530 that won’t start. I appears my air flow sensor switch is missing, maybe knocked off by a branch. Can’t find it listed in my user or parts manual. Does yours have one? TIA 0 Reply Insert Quotes Post Reply
