500 four rectifier
Bryanj:
If you wire it up permanently fully charging, any time you run with the lights off you will boil the battery and any time with the lights on it don't quite charge enough , Tucked if you do and same if you don't!!!!
Only answer is emulate a 70's Triumph and fit a well cooled, high amp Zener diode
Lobo:
Yup Mjc, Bryan has a point which is why I asked in the last post "do you have a voltage regulator in the system?"
If not, can I suggest you leave the headlamp wiring as Honda designed..
If yes, then wire as the sketch... or Bryan's suggestion. (a Zener diode only allows a certain voltage to flow... think I saw your generator is capable of 110W implying you'd need a 10A Zener minimum)
With electric start, congested / slow roads and our tendency to drive with lights on 24/7 I'd be reckoning to wire it in the 'full charge ahead' option!
On a couple of wiring diagrams I saw there was no regulator... leaving me to think the perm magnetic generator is pretty 'weak' and the regulation left to the battery in the system. This too would explain the supplemental winding for 'lights on'.
But... I've also seen CB450 wiring diags showing a regulator. So, confused.
Anyways, enjoy the fiddling...
Simon.
Woodside:
Ok
I found this in my box of treasure?
Perhaps it will do the job
Bryanj:
Nope, thats for a gereator with a wound field coil (400,500,550,750). Yours is a permanent magnet rotor. The only thing that will work properly is the correctly wired original type switches or wire it all permanently charging and use a zener.
You seem to be intent on going your own way and not listening mate
Woodside:
No Bryan
I am listening I honestlythought that was it....
Thanks for putting me right.
I'll be looking into a zener diode this week then. The only reason I have not yet is because I was certain I had a regulator somewhere but I was not aware it was the wrong one....
Or indeed no good what so ever
And once again I appreciate all the help
