Re: [DucatiST] Melted wires on 99 ST4

 

This also sounds like good advice (after I check the system for faults) I've heard of this mod before but it never occurred to me to try it. The stock VRsits with the fins in the intake air stream, so I thought it shoud be running pretty cool.

Thanks very much for the feedback, I certainly appreciate the help from everyone here on the forum!

The fix, which I have done is, to fit a mosfet regulator, these are fitted as standard on most late Yams & Hondas & can be obtained cheaply from breakers, and hard wire the leads into the loom without a connector and/or run extra leads to the battery.
