new here…did a search and found this
My headlight just went OUT at the same time that my starter went out…press the starter button and…NOTHING…doesnt make a sound.
However, if I hold the starter button in, the headlight actually comes on…goes off again upon release.
While I don’t care much about the electric starter, i need the headlight.
Couldn’t figure out why the headlight is tied into the starter somehow.
So what do I need to take apart and fix (its okay to talk down to me like a 4 year old…in fact, given my mechanical skills, its preferable)
Thanks in advance
oh yeah, 76 cb400f
The START buttons are frequently corroded on these bikes, from years of sitting. They need to be cleaned to improve on this situation, and if they are used more often they will work better. Don’t use a halogen headlight with the 400F and this START switch, as it will slowly burn the contacts (like the 750 and 550 bikes do).
You can often clean the switch with electrical contact cleaner or CRC Brake Cleaner: spray some in, work the switch a number of times, repeat as needed (at least 3 times). It will work better for a while, then you’ll have to repeat this process a couple more times over the year before it will become reliable again. Operating it will slowly wear away the corrosion it now has.
The switch is unobtanium now. Disassembling and cleaning the switch itself, with reassembly, is possible, but not for the impatient of feint-of-heart, as it is VERY hard to reassemble.
