Quoted from pinhead52:And if you finally come to the conclusion of a bad transformer.... I have one out of a Night Rider I can offer up
And if this is the case, the next question will be "why did the transformer fail in the first place"? Is there a dead short on the secondary somewhere that damaged the transformer? Why didn't the high side fuse blow? Best thing is to check those things out before just replacing the transformer and hoping for good results.
