1977 CB550F
Just put it back together with a Dyna ignition and coils.
Went for a long midnight ride last night and as soon as I get into the middle of nowhere (about 40 miles in) everything dies.
It is pitch black, my visor was fogging up, and I'm mid-turn on an unfamiliar road going a little too fast...lucky I didn't wander off into a ditch...my heartbeat kicked up a couple notches for that one...
I manage to bring it to a stop on the side of the road where I find the main fuse has blown and melted the fuse box along with it...
It also managed to get hot enough to melt the solder on the back of the connection (there were little balls of solder bouncing around inside it)
Now, it might be worthwhile to note that when I took the bike apart, I noticed a jumper wire going from the bottom post of the headlight fuse to the bottom post of the main fuse so that the 7 amp and 15 amp could essentially share the load...I inspected the wiring diagram decided to discard it and see what happens because it was obviously not and OEM piece.
Well, the bike obviously ran pretty well for 40 miles, and I can't really think of any specific reasons why it failed all of a sudden. But chances are, this was a problem before I owned the bike, juding by the presence jumper wire across circuits.
So far my list of things to check are:
--Short at the coils (because this is obviously something different that could be causing a problem)
--Extra current draw from the DYNA could be causing the voltage regulator to get pissed off and run a little too hot???
--Check for a short somewhere else within the system...not sure the best way to go about that one...but it is probably my best bet given the fact that this problem seemingly existed before the modification.
Any other thoughts on this one?
