you might remember my electical issues from this thread: https://www.vn750.com/forum/showthread.php?t=2393
as a recap, my ignition switch was cutting the power off sporadically while i was riding and immediately after one of the 'power off' incidents, the voltage readings spiked up to 17 volts. when i got the bike back to base, i discovered that the r/r had been fried. also discovered that the negative battery lead had snapped off (not sure if this happened when i was taking the lead off the battery or while i was riding).
so... new ignition switch, new electrosport r/r, new negative battery lead.
i took the bike out for a test ride today. at 5000rpm, the voltmeter was reading about 14.5 volts. when i got the bike up to 6000rpm, the readings dropped to the low 13's... 13.1, 13.2 volts. when i pulled off the highway and stopped at a light (idling at 1000rpm), the readings were in the low 12's... 12.0, 12.1 volts.
two questions: 1. is the drop in voltage when i increase the speed from 5k to 6k rpm just a product of the regulator 'regulating'? it seems like 5k rpm is the sweet spot for the r/r. 2. at idle, 12.0 volts seems a little low. does this seem right? granted, it was fairly warm out today and the fan was probably running, but anything less than 12.5 volts scares me a bit.
the only thing that comes to mind is replacing the battery. this battery is new as of july... just wondering if the incident with the voltage spikes might have damaged the battery.
