Hello everyone,
I am in need of some mechanical/electrical advice please. This will be long, so I will try to explain my mess the best I can. The issue I am having is that the skid loader engine runs only as long as I hold the ignition key on in the "start" position. As soon as I let go of the key the engine dies. I have the 3 cylinder diesel Isuzu 3KR1 engine in it. I have a 1 year old battery in the machine, I thought the alternator was my problem, so I had that tested, it was fine. I did have new bearings and brushes put in the alternator as long as it was out. I just installed a brand new ignition switch in today thinking that was my problem. No, that wasn"t it. Engine dies when I let off the key just the same as the old ignition switch did. All the fuses are good that I can find. I have looked over the wire harnesses so many times for problems, but don"t find any. When I sit in the cab as I start the engine, I hear some kind of "clicking" sound behind me to the left either in the corner of the cab or in the engine area. I can"t pinpoint this exact noise myself. But it does the same noise every time the engine dies when I let off the ignition key. I checked the 2 wire harness plugs in the corner of the inside of the cab. The back plug seems to have a wire lug/terminal broke off but I am not sure it makes electrical contact when the harness is plugged in again. I also had the starter relay tested from the "dash" panel and it tests ok. My operator"s manual doesn"t help me and I have down loaded the shop manual on my computer to with no help. I am really stumped with this issue. I really believe it is an electrical issue. And electrical diagrams are like algebra to me, they don"t make sense. I appreciate any ideas/advice anyone may have for me. I am trying to not have to take it to the local dealer if I can help it. Thank you everyone.
