I have a Farm Pro 2420 model tractor. I am new at owning a tractor and all has been well. I have 8 hours on my new tractor and now when I try to start it the main fuse blows. My gauges and everything else works till the fuse blows. Can anyone help with this maybe something little causing it. If not I will make the haul back to the dealer. Thanks for any help. /forums/images/graemlins/confused.gif

With just 8 hours on it, the dealer should fix it free. It sounds like you have a simple short somewhere -- a wire has come loose and is intermittently grounding out. Call them, they may have an idea where to look.

Thanks for the reply I called them and they said to look at the wires coming off the starter and just my luck they are all taped up but what I could see all was fine so it will be hauled back and let them worry about it maybe it won't take all day with someone that knows what they are doing.

Unless you're hauling it, they might find it cheaper to let the guy driving the truck fix it at your place.

It it is not a short, a weak battery can cause excessive current to flow, thus blowing fuses. Also.. check the fuse value.. some tractors, like NH in particular, have had to have a service bulletin due to having a fuse that was underrated in
the ignition system.. etc. Still.. at 8 hrs.. I wouldn't even turn a bolt on it if it has a warranty...

Hello Mjack, If you have a multimeter , test your voltage at your battery, should be 12v when the tractor is off, 14.5 volts when running. That will tell you your voltage condition of your battery and if the alternator is charging it. If this checks out then you probably do have a short or a fuse that is underrated. To test for a short simply disconect your positive terminal from your battery and put your multi meter on the 10 amp dc scale. Make sure everything is turned off on the tractor and put your leads in series with the disconected lead and the terminal on the battery. If you have current flow with all devices off you have a short. Reconnect your terminals on your battery. Now follow your main cable up to your fuse box and remove the fuses one by one working from the main down . Put your multi meter in dc 10 amps again and test from the line to load side of your fuse terminals. By this process you can narrow a short down to the wire its on. From there a good inspection will be needed, tracing the path of the wire from this point. As others said here with 8 hours on the tractor this should be a dealer issue.. Good luck
