KH 125 blowing bulbs

[Moxey]

Morning

So I finally managed to rig up a reg/rec to the KH the other night (utilised a 6v CG reg/rec) got it charging the battery with DC etc however I now have an issue with it over revving and blowing bulbs (ruled out a bad earth or vibration).

The lights run directly from the stator so the wiring diagram would have me believe however I trialed a few last night and it blew them all when revved to 3/4 max, that was 2 6 volt bulbs and one 12v bulb (all 35w).

Been thinking if I could perhaps run it from the battery instead of the stator as that is already regulated? Alternatively I've been considering wiring in a zener diode between the stator and the lighting circuit.

Am I missing anything or in theory should this work? Electrics aren't my strongest point.

Thanks

If you're running it straight from the stator, is it not bypassing the reg/rec? It can't get a stable voltage from the stator/generator.

Indeed, the voltage to the headlight is un-regulated but this is as Kawasaki specifies according to the wiring diagram (the Yellow wire from the stator), the reasoning for such I can only think is that the 6 volt battery is too weedy to run all the lights from (just the stop light I believe) I did consider modifying the loom to run it from the regulated battery but I'm unsure if it would work.

They did that when new.....

From memory, the tail lamp is fed off the battery anyway, so that it's lit when you turn the ignition on.

Brake-lamp is off the unregged AC-Direct, that should only be available when the engine is running... and if you is braking, engine shouldn't be being revved....

Eliminate the daft, first.. make sure the bulb is in the right way / connections are the tight way round.

Next EARTHS... most common cause of blown bulbs... apart from the fact little Kwaks were notorious for it; and a high resistance earth, making electric take path of least resistance, often back through tail lamp filiment, giving it double the amps to make it pop.

Should be reasonably reliable if all is as it aught to be... though as said, they were never great even when new.... may be worth adding a diode, not a zenner, they work back-ards, on the tail-lamp to stop un-regged stop-lamp volts back-tracking through it, but wont do much for the surge and spike on the stop fillement on AC, to which the suggestion is to not blip the throttle when you have the brakes on!
