Thanks for the kind words Chuck! I am glad you found the problem!
Everyone on a 2002-2003 VTX 1800 should look at their 2Pconnector and relay connector.
Many run cycles, electrical connector oxidation with high current = failure. The intermittent nature makes it a PIA. Dangerous also.
Just unplugging it and reconnecting it makes a better electrical connection(scrapes off oxidation).A little bit of N0-Oxide or silicone grease may help but once the tension on the wire terminations is gone---high resistance/open.
Hey, I just came upon this reply from you and I have a 2002 1800C....which 2P connector and relay connector are you specifically talking about??? I read the rest of the posts and didnt really see which ones I need to look at. I would really appreciate this info cause my vtx died and has no power going anywhere. Ill check the 30amp main fuse tonight, but all otehr fuses are OK. My email is email@example.com cause I dont think i am a member here yet. Im a member on VTX cafe.com . Thanks!
I see that location of the 2P connector on the left side from your pic, but is that the 30amp main fuse location that I see just to right in that same pic? I have similar issues and need to get home and look at the left side fuses. I only checked all the main fuses on the right side fuse box with the 5 fuses.
