Donaldw Posted November 25, 2023 Report Share Posted November 25, 2023 Hi Last time I was out on my txt 300 noticed some smoke coming from below tank, had a look and most wires for the fan were melted and charred. On Futher inspection I saw the thermostat module/rectifier/ regulator (saw it called a few things had basically melted . Are there any specific causes for this or should I just start replacing parts. Thanks in advance just looking for some knowledge. Quote Link to comment Share on other sites More sharing options...
lemur Posted November 25, 2023 Report Share Posted November 25, 2023 4 wires and connected to the DC fan motor would make it a rectifier. Overheating of that component would indicate too much current input, too much current draw, or a short circuit somewhere. You need to test everything from the alternator to the fan and thermostat and lights. 1 Quote Link to comment Share on other sites More sharing options...
lemur Posted November 25, 2023 Report Share Posted November 25, 2023 …. Your alternator outputs AC power and this is the device that converts AC power to DC so that DC devices can use it. Quote Link to comment Share on other sites More sharing options...
Donaldw Posted November 25, 2023 Author Report Share Posted November 25, 2023 Thanks for that, I will start to get everything tested 👍 Quote Link to comment Share on other sites More sharing options...
