Ok, I'll post up some pix and offer a few of my opinions. Put a buck fiddy with it and get yourself a cup of coffee maybe.
here we have a mess of alternators....... I'm an alternator kinda guy if you didn't know.
the one closest to you is a CB350 unit...... unless I've gone totally senile
possible I suppose
now the one closest to you is a 180 watt single phase Lucas unit
damned fine alternator..... can't say much for any of the English factory wiring but the charging system components are bullet proof
the one behind the CB is an Italian alternator just a few ticks under 400 watts
really damned fine alternator
the one to the left of it is a 150 watt alternator
notice how much physically smaller all of these units are than the CB350 unit
now the standard Lucas alternator is a 135 watt unit and it will indeed run point ignition and DOT lights without a battery
yes the lights go brown at idle and you have to set the idle up so it doesn't die
and it's much more reliable with 5 ohm ignition coils
The 180 watt unit will do it no problem but you'll still have lights dimming and flickering a bit at idle
Note: the three phase Lucas units aren't really great for batteryless running simply because they don't have a high enough peak voltage at slow speed to make the ignition happy....... even though once running they do put out a bit more juice at idle speeds than the single phase units
Now the 150 and 375ish watt small units...... they will do it and the big one (single phase and very peaky) will do it with 3 ohm coils, electronic ignition, and H4 headlight
ask me how I know
I also have one of these 180 watt Lucas alternators on one of my HD's and it runs DOT (not so legal) high wattage headlights but the ignition is fired by a Fairbanks Morse magneto.... but I am sure it would light off points ignition too even if I had to run legal bulbs
I have one of the big single phase units on another HD and it lights off electronic ignition and powers non-DOT legal lights as well, LEDs in the rear though
glad to show you if you care to see
sooooooooo....... I don't know what the output of this CB unit is....... I just recall keeping it thinking it looked like it had potential
but if people who have tried have decided it just isn't enough to run ignition and lights
well Honda dropped the ball and if I was doing one........ I'd stuff a good alternator in one a
ny of these shown in these pix are smaller so I know they could be made to go without having to get too kinky with cases and such
but certainly I can see that it could be run batteryless
by simply running the output to a rectifier and then the B+ to a stack of sinked diodes to regulate or clip
or you could get fancier and build a proper regulator
less than ten bucks plus time spent
but I cannot see any reason why a Podtronics or Tympanium/Sparx unit wouldn't handle both rectification and regulation just fine
do any of you know the rated output of the CB alternator?
what coils (ohms) do they use stock?
