I saw a post from last year that alluded to a problem with Honda charging systems.
Can anyone enlighten me more, as I may be having this problem
'96 VFR 750, with I think the original battery, 23k
Always started fine since I have had it and previous owner mentioned nothing, but I do not think he rode very hard.
After 8 plus hours at high speed, high revs, and very high temps the battery was dead.
Meter showed 12.5 vlts but putting lights on dropped it to 4 and no crank what so ever. Over night it totally died to where the clock even stopped. My thoughts at the time were old battery finally packed it in, charging system must be okay or it would not have had the 12.5 surface charge.
Bump start the next day, ride moderately for 5 or 6 hours, bike starts just fine after running for 10 mins., and for the rest of the day, started and stopped numerous times, no problems.
Next day, today, I am at home and can do some more diagnostics, as the batter now seems just fine.
Sitting at 12.6 vlt, running at low rpm 13.5, running at 9k 14.6 vlts. Lots of reserve, I had the lights on for 1/2 hour and battery held fine, yet was stone dead the day before.
This scenario familiar to anyone. Could the alluded to charging problem have cooked it on the long hot ride, but did not totally destroy it. I feel that the 14.6 output at 9k is a little on the high side, but it is not 15 + ..
I have no problem believing that a 7 year old battery is bad, but if it is a charging system issue, I'll deal with that first.
