Lights and handwarmers go off and on

I have a 97 Indy 600 that the lights dim, go off and come back on also the hand warmers go off and on. Read some posts about this problem but they were older and just want to make sure that it still may be the regulator and also they said that it was a little black box and hubby looked today and he said that he only saw a little silver box up by the pull start not by the key/choke...I am going to look tomorrow, just want to make sure I am looking for the right thing...thanks.

Lank - your thread is an interesting read, but I don't see how you actually had a problem that needed "fixing" in the first place (over-voltage). Battery charging works on the principle that current flows from higher voltage to lower voltage. Since the "power" produced by the sled is constant at a given RPM, the voltage will drop as the current flow increases and vice-versa. So, when your battery is nearly fully charged, the current flow drops off to essentially none and the voltage will raise as a result. If you're concerned about the voltage being too high, the fix would be a regulator I'm speaking of a regulator in-line on the charging circuit, not the one that handles voltage regulation for the entire electrical system).

As far as lights flickering and going on and off... If this happens while you're driving the sled, and not just at idle, check all of your grounds very well. If the voltage regulator goes bad and you rev up the machine (like you would when riding), you will typically fry anything electrical (bulbs blow out). A simple test is to unhook the regulator (it's on the right side of the machine, behind the console where the choke and key-switch are) and start the sled. DO NOT REV IT. If the lights come on and stay fairly constant, the regulator is likely bad. If the problem persists, however, you have grounding issues.
