Default Voltage regulator making noise???

Battery is charged, unhooked from the charger/maintainer. But the voltage regulator is making this low growling noise still 45 mins after the charger is unhooked. What is that? Is this normal? Do I have a bad voltage regulator? Is it a recently charged battery thing?

Help please

This is not my specialty and I hope someone chims in to correctly if I am wrong. I think your Voltage regulator might be done for. If you hooked up your battery correctly and per a previous post I think your charger will not let it reverse on you I am almost certain your regulator is gone.

Tech guys chim in if I am right or wrong with my conclusion.

Sorry for the dual posts, but the first post was when the battery was been charged.

Now it's doing the same low growling noise without the battery maintainer hooked up. At least 45 mins after been unhooked.

Could the battery be overcharged and the regulator is reducing the voltage?

Ok you really have me messed up now. Is the charger making the noise or the bike? I have had chargers that made a growl but not a bike. If the bike is making the noise take that charger off and carry it to a mechanic or at least talk to a mechanic. Your bike should not being doing that. I must have misunderstood your first post.

try unhooking your battery for a few minutes, then reconnect and see if it still growls. Todd

Does it growl like an African or European swallow?

There was a recall on some voltage regulators on some models. I can't remember the exact years, but I have an 06 RK Custom and the dealor replaced my voltage regulator per the recall. There was a post on the forum some time ago. If you do a search you might find it.

I have never had a voltage regulator growl.

get louder pipes

j/k
start the bike, at about 2000 rpm you should get 13.5 - 13.8 volts at your batttery with a tester. if you do, your regulator is doing its job
