| i have a problem with no brake lights so i changed the bulb anyway and ran the bike for a minute at the most with the bulb holder removed. still no brake light, only tail light lit, but the bulb is literally too hot to touch. is this normal? |

| 1st these are old style bulbs they get fairly hot, if your meter/gauges and horn works is not the fuse, not a short, if not check fuse "B", if burnt, replace, but it may fail again if there's a short somewhere ??, otherwise it could be brake levers, brake light switches, yes, they can both fail/get dirty contacts/loose connectors, usually not at the same time, you usually notice when 2nd one fails, a jumper across connectors on wires should illuminate brake light , the switch is the one with spades facing in on either side. Sometimes spraying switches with WD40, etc. can restore them, Good Luck. |

| WD40 is a light oil and not the best thing for electrical work. Most auto parts have specific electric switch cleaning sprays. That is what I prefer. Something like this:

On a switch that sees frequent use WD40 residue is not really an issue as the lubricants are very volatile/short life. That's why WD40 is a better (not the best) for loosening rusty parts, but poor for lubricating. BTW, I have CRC on my shelf, only use on contacts. |
