2155 electrical problems

[tinkinpiddler]

Hi, I need some help. My elderly neighbor has a cadet model 2155 that won't start. I went over there today to help him with it. I checked and cleaned the battery terminals and then both cables. They were clean to start with, but cleaned them again. Battery is fully charged. I cleaned the ground wire and the engine ground connected to the starter. I also checked the ground wire for continuity and I checked the two fuses and they were ok. We tried to start it again after I did the previous steps and nothing. He wanted to take the starter off and do a bench test on it. I did and it worked fine, I tested it both ways, with and with out the solenoid engaging. I then put it back on. I then asked him to turn it over with the key and heard a pop. I looked at the fuses and the left one was blown. (red wire, red wire white tracer on it) I put another fuse in and he turned the key over and it blew again. I looked the whole harness over as much as I could see and it looks fine. I couldn't see any spot were it might have shorted out as the cover on the harness was in excellent condition. He said the tractor was five or six years old and is great shape. He did have the seat switch disconnected, but he said thats been like that for awhile. I told him I didn't think that matters, I am not sure. I was wondering if it could be the voltage sensor module? I don't know if it could be the key switch. I sure would like to know what it could be for him, as he said the place where he had it serviced before took advantage of him. I would appreciate any ideas or help in this matter. I just don't know what to look for since the ground wire and starter are working. Thank you very much.....tink

First you need to find out why it now blows the fuse and it didn't before you pulled the starter..you must have a wire touching where it shouldn't. Then how about the switch for engaging the blade? if it is out of adjustment or bad, It stops the engine start procedure so you don't start the machine with the blades engaged. Check the seat switch..is it still disconnected? Reconnect it and give it a try. some of them prevent start unless someones on the seat. There may also be a brake switch that makes you step on the brake in order to start the engine..Is that one working? Lots of safety switches in the system..Let us know!

well I found out what it was. The switch actuator spring was broken and not engaging the brake switch. Thanks for your input.......tink
