Headlights and daytime runners out.

[JaredWarne93]

I have a 93 1400 and about a month ago I was heading home from work and suddenly slowing to a stoplight my low beams went out. Luckily my high beams still worked. I checked the bulb and saw it was still ok. Odd. So I rode pushing full brights for a few days and then bam. No high beams. Awesome. I've looked into the bulb again and now it's actually burnt out and my bulb connector is slightly melted. So I purchased a new connector. This one only had 1 wire for each pin. Where as the old one had 2 hots and 2 grounds to each. Rewired it to the new one with bullet connectors and nothing. No lights still No fuses blown. Cleaned small amount of corrosion on switch.. No visible grounds loose. I'm at a loss. Wire diagram available here I've seen multiple times. Can't find an issue. Any tips?
Ps. Also horn doesn't work. I can jump the horn with a paperclip. But switch is shot? Turn signals work just fine.

Electrical is most always a headache.

Without going through a Wire-by-wire continuity testing procedure. I'd first make a quick check the switches/wires on the Handlebars. They hang out there in the weather, and might be your problem-source.

I have had a lot of trouble with the horn and headlight switches, mostly because when I was working the bike sat outside all day, rain and shine. I have also gone through 3 horns.

Was the bulb you replaced the correct wattage or a higher wattage? Could be you were drawing higher watts than the wires could handle and you burned up the wires in the circuit. The week on constant high beam could have put it over the edge. Are you getting power to the new connector?

Are you getting power to the new connector?

After you verify you have power at the fuse and they are good this is where you start to troubleshoot.

I always run highbeam during the daylight hours, never caused a problem.

Is there a chance that you lost the ground somehow?

I would start tracing the power backwards from the head light. if you have power at the headlight then start checking the ground.

I think you said you have the wiring diagram that is on this site, if not let me know and I will post it.

I just mentioned the high beam because if the bulb that was taken out was of a higher watt than standard that can put a strain on the wires. The connector was melted which makes me wonder if the bulb was of the right watt.
