Tractor on fire
We rebuilt the fuel system and fitted a new fuel pipe on the D160. We then connected a new battery and started it up. It ran well for a couple of minutes, then smoke and flames started coming from under the battery tray. We switched the tractor off and investigated. The regulator had shorted out and ignited debris. It was a bit of a shock but fortunately only a new regulator is required, unless it has killed the stator.
