[QUOTE="69ST, post: 185422, member: 5"] Hadn't realized an 1157 bulb drew quite that much. I agree with you, as in I'm practicing what I preach with this...the system, in my bike, has had no problem keeping up, even charged a drained battery...all lights on...in a 90-minute ride. That's been good enough enough for me, though I'd like to know how much output the system has. One testing caveat is that a charged battery can power an automotive headlight with nary a trace of distress...for a time. Best, educated guess, a 55W bulb would need somewhere between 30-60 minutes to drain a 12v/5.0ah battery, engine off. Running a partial-loss system could stretch that out more than enough to lead one to a faulty conclusion. A relatively small (5-20W) charging deficit, wouldn't discharge the battery for hours. For example, at -10W, there's ~5 hours of usable current, before the battery is discharged. Since 5-hour rides are kind unusual, this could take days, or weeks, to manifest. At the same time, the reg/rec needs a healthy battery to operate normally. Hence the suggestion to monitor system voltage. [/QUOTE]
