miketomcat Posted October 23, 2017 Share Posted October 23, 2017 The truck is a 110 with a disco 200tdi. This morning driving to work I smelt hot metal a quick check showed a hot alternator and the warning light came on and stayed on when the engine was shut down. If I start the engine the light goes out. I've disconnected the battery which has turned the warning light out. I had no problems yesterday. So do we think the alternator is toast or would a regulator pack(I have one) fix it. Mike Quote Link to comment Share on other sites More sharing options...
simonb Posted October 23, 2017 Share Posted October 23, 2017 More likely one of the diodes in the rectifier has gone short cct. More off a faff to fix than a regulator (need big soldering iron to disconnect the stator windings). Might be best to look for a replacement/recon.

miketomcat Posted October 23, 2017 Author Share Posted October 23, 2017 Thank you for the reply. I have replaced the alternator and yes duff diode is the conclusion I've been given by TSD. Mike Quote Link to comment Share on other sites More sharing options...
