Hi guys Got a bit of a problem with my 04 VFR 800 vtec. Had a flat battery last week as its been on there for the 2 years I've owned the bike I bought a new one. Fitted the new battery all good. Then I noticed the Scott oiler needed bleeding so left it ticking over for 5 minutes or so to run the oil through the pipes with the seat off. Noticed a whisp of smoke from the battery area and found the Red wire that comes off the positive terminal of the battery which has a 30 amp fuse a joiner and goes to a plug behind the battery was very hot. Checked it wasn't over charging. It seemed fine. No silly voltages even when revving. Any ideas before I start to strip it down and chase the fault?? Thanks in advance. Shane.
Is this wire coming from the rectifier? If it is, check the terminal at the battery, if the wire is getting hot it's because there is a bad crimp or joint at that terminal. If the wire is sending power somewhere else, check the connector on the other side of this wire for the same. Heat happens when power reaches a high resistance joint.
This is a common and known issue, the wiring harness and connectors in the charging system are crap. The wire is undersized from the main fuse. Cut it out with the fuse holder and replace with a new one (12g wire on the fuse holder). You will also want to look at the threads titled "The Drill" and "Electrical Loads"
Will make it easy as I am not sure many who may not frequent this site often know what is being referred to. The Drill http://vfrworld.com/forums/showthread.php/39277-How-to-fix-common-regulator-Stator-failures Electrical Loads http://vfrworld.com/forums/showthread.php/50566-Electrical-Loads
Jeff Sir you are a star!! I ordered a 30a fuse holder with 12 g wire. Went out to prep the bike for fitting it when it arrives to find someone has already fitted one exactly the same. Unfortunately the numpty had use crimp connections. I removed both of these. Soldered one wire directly to the original spade connector and spliced and soldered the other end. Ran the bike for 15 minutes wires were stone cold. Problem solved. Many thanks to you and the other guys that replied. This is why I love forums. Cheers guys. Shane.
Problem is and it comes up often when you tell people to solder and heatshrink the wires and then they come back a bit later and say they have reused the same type of connector that failed in the first place, some people just don't listen
Every time I read a thread like this I cross my fingers and put my head back in the sand. I know that my bike didn't go in for the wiring recall. I know that I should do the drill and upgrade the wiring. I know that I am tempting fate. Jeff_Barrett has even posted a very good "how to" and made it even easier by posting pictures. This winter when the snow flies I will do it. I promise. Those of us that haven't, should. The only excuse after learning about the issue and repair is stupidity, I shall claim this.
