Action P102 DB Fairmount Alpine / P 93 version 3
Well the car is sorted £275 later , now back to the boat . Well you were right yet again Dave it was the fuse .
This is the action taken ,disconnect T5&T6 fit new fuse ,switch on all ok .
Switch off .
Connect T6 feed to amp and decoder ,switch on , all ok .
Switch off.
Connect T5 feed to P93. Switch on fuse blows , switch off .
Disconnect T5 fit new fuse ,switch on ,OK . Switch off.
Disconnect feed to bow thruster after P93 . Switch on .Fuse blows .
This to me points to the P93 as a source of my problem
Remove P93, removed cover . No damage visible ,no smell.
Check heat sinks ,not touching ,OK .
Looking at the diagram on the P 93 for bow thruster, just to confirm set to mode 6 ,7.2 v out to thruster .
This is where I am not sure of the connection if I have it right , as I understand the diagram the two centre go to the thruster ,it will not matter which way round thy go that why it's in yellow .
Is there any test that I can do to fault find , I only have a multimeter.
Thanks for the help
David
