New rectifier but....

[Guest]

...the charging at 5000rpm is near 17 volts.

Should I be concerned about cooking something?

If your using a Honda RR , did you connect the black lead to the rear brake light switch to provide it with a reference? The Honda uses the black lead to read how much the bike is using. Splice it into a wire that is 12 volts with the key on.

Your recifier/regulator is not regulating.
It could be broken, it could have a bad connection on a sense lead, maybe something else

It WILL cause the battery to gas (a lot probably)

I would not ride it like that.

Check the battery fluid levels, if they are low, refill with distilled water.
