Negative Battery Lead Melted

Hi all,

1st post...been lurking around here for a little over a month. Lots of great information that has helped get my new-to-me vn700 up and running. Had planned to post first in the pics thread once I have a chance to clean her up a bit more but alas, I am having a strange issue and thought I run it by you guys.

Put about 90 miles on the bike last Sunday and I was very happy with how it performed. On Tuesday I went to startup the bike and it wouldnt turn over. Instead I heard more of a clicking noise from under the seat which was immediately followed by a cloud of smoke. The insulation on the negative battery lead had begun melting away. The coppers fibers appeared to be intact as did the inline jumper, just the insulation damage.

Finally has time to take a harder look at the problem this morning and wasnt able to identify any loose/frayed connections anywhere. I tried the ignition again after electrical taping the exposed fibers on the negative battery lead and reconnecting the inline jumper. I noticed that when the ignition is engaged the clicking sound is coming from somewhere related to the positive battery lead. I can actually feel pulsing on the positive lead when engaging the ignition. I also found that the headlight is not coming on. Nor is the indicator when high beams are engaged. The wiring behind the headlight as far as I can tell is OK but Im not an experienced electrician.

I have to run out this afternoon and will pickup a multimeter to see if I can trace the problem. Also, I have not yet checked the fuses but will go through my manual and do this today as well although I cant see this being the problem.

Has anyone had anything similar occur?

Did you check the ground connection at the frame? The click is the starter solinoid tring to get power to the starter. My guess is the frame ground, clean and reconnect. hope this helps you.

Thanks for your input niterider. I did clean up the ground as suggested. It didnt solve my problem but was dirty and needed nonetheless.

Ultimately, I found the issue. The center stand had all but smashed and shredded the wire that runs from the starter to the front of the bike. Not sure how it got in the way of the centerstand but this was causing the short.

Went to Advance Auto and picked up a 40" replacement, installed it and now I am back on the road!
