Stator Prognosis Needed

Why wouldnt hooking it up the original factory way (minus the extra Yellow and White/Blue) keep it working without burning up the stator?

I remember running my other 78 back in the 80's without the light.
The factory wired your 78 so that the headlight switch openned one loop of the stator output when headlight was off- this dropped the stator output considerably,so less heat was generated.
If you run with headlight on ,best to follow oldvet66's advice and wire the stator direct to a decent R/R-
 
ok, so, if I leave the extra yellow and white/blue disconnected.... AND I somehow accidentally turn the headlights off... how long till the stator fries?

AND other than the stator, do you have any idea what would cause my battery to only show 12.29 volts at idle AND at 4k RPMS?
 
That I couldn't tell you. I'm guessing it's not immediate. It's required by law to have it on all the time, so don't turn it off. Usually whatever beam you use most of the time goes first if it blows out (I always use the high beam in daylight), just switch to the other beam until you can get another replacement.
 
If the bulb burns out in the daytime, and you don't notice, how soon will things fry?

I run my bike with the light off quite often, as dirt roads will break a hot filament much quicker than a cool one. Sometimes I do it for the stealth aspect, sometimes I just forget to turn it on. Because of this I always left the stator loop going throughout the light switch. I know a lot of you guys remove it, have any of you had a headlight burn out and take the rest of the system down with it?

Poor connections? Have you tested the R/R yet? What R/R is currently on the bike?

So on the end of the bundle near the battery, are the two yellows and two white/blue connected?

There may be instances when I may want the light off.... and another switch to turn the brake light off also. Lets say, when I'm off road.

Just use spade connectors joining the stator to R/R, that way if your headlight bulb burns out or you choose to run incognito, unplug one stator loop connector and you'll being doing the same thing the headlight switch did!
 
Hot / Cold filaments??

Hot / Cold filaments??

My first post to an existing thread.. In 1973-74 I worked in the engineering dept. of an automotive lighting company. We had a very noisy machine for vibration testing truck lights; there was certainly a difference between the life of a hot or cold filament, BUT it was the cold / off ones that failed way sooner; theory being that the filament was more ductile when hot, or more brittle when cold.
If you have a voltmeter and see it dropping below 13v or so. then losing your headlight can get you home, btdt with a Honda turbo..
Amazing some of the stupid stuff I remember, now what day is it??
Cheers

Hey, you edited a post while I was typing! and my computer didn't like it.
