Would the headlight and a stuck brakelight switch overload the electricals on a CB400F?
I went for a ride with buddies on a warm day and after a couple hours, we stopped at a store and my bike died completely when we pulled in. No more lights, no nothing. The main fuse was the culprit. It had "undone" itself without blowing. Might have been a old fuse, I don't know, but the same thing happened on my way home. My wife brought me some spare fuses, but as soon as I got home I investigated and realized that my brake switch was stuck on, which might account for the problem. Nevertheless, I undid all the bullet connectors and put some conductive grease on all of them, as well as most of the moulded ones (didn't do the ignition lock). Beforehand, the right side of the main fuse would get quite hot. Enough to melt a dimple in the plastic cover. This morning, I rode for 30 minutes and the fuse stayed cool to the touch.
I also jury-rigged a switch and a relay for the headlight, but I decided to run with it on to see what was what.
So, could the stuck brake switch along with less than ideal connections (and that damned headlight) be enough to create enough heat in the fuse socket to melt the thing? Without blowing either of the 15A fuses that unsoldered themselves?
