got a question on a strange electrical issue I'm having with my 125. I put a small LED volt meter on it and every so often while at idle the meter will blink out very momentarily for just a split second then come back on. Its wired directly to the battery and it only happens when the bike is running and so far I've only seen it happen at idle but its kind of hard to watch it and drive at the same time so can't say for sure it doesn't happen at speed. My question is, with the meter wired directly to the battery is there anything that could happen with the electrical system, charging circuit or otherwise that could cause it to momentarily register 0 voltage at the battery, other than the meter being bad? It would seem to me that even if you lost output from the alternator or had a short somewhere beyond the battery all that would happen is that the battery voltage would drop to its non-charging voltage. I've checked the wiring to the meter and all connections are tight and wiring is all new. No matter how much I jiggle the connections the meter does not show the same symptoms.
I installed it due to the fact that sometimes when accelerating hard the bike will lose power and hesitate like what would happen if the carb bowl ran dry due to the float being set wrong and it always recovers as soon as I back off on the throttle and then accelerate more moderately. I've pretty much ruled out the carb as being the issue though and noticed that having an extra electrical load with cause this to happen like when the blinkers are working or headlight on which is why I think its electrical in nature rather than carb related. The electrical system on the bike is very rudimentary, no voltage regulator just a four diode rectifier from stator to battery. problem is I can't really pay attention to the meter when it happens cause, well, I'm paying attention to the road and traffic and the meter can be hard to read in bright sunlight. Really need to ride it some evening when I can really see the meter display but with a 6 volt lighting system I don't want to caught in full night time!
Any ideas on either issue?
