Volt meter and radio stop while riding down the Highway

Postby Mick83 » Mon Aug 31, 2015 8:28 pm



I've been noticing my volt meter sitting under 12v shortly after I take off. I checked the 3 yellow wires and they are putting out 5+ Battery has been checking out at 13.5+ When I got home after using my truck to run to the Doc it fired rite up no Probs.

I have had a similar problem with the voltmeter and radio on occasion, which I've never found a permanent solution for, but have found an on-the-spot fix for.
I'll occasionally notice during a ride, my voltmeter reading down to zero and the radio will not work (Usually all the fairing mounted instrument panel gauges & lighting is out as well). The first several times, It all began working again at some point during the ride (vibration?), but I never realized what had affected it, positively or negatively.
On one ride in particular, I noted the problem, and began pushing, pulling and wiggling various things to see what I could make happen. I realized that by simply wiggling my ignition key more firmly towards the run position, everything began working properly again. It may be a case of worn contacts inside the ignition switch (Maybe a large key ring with the weight of many keys vibrating?) causing the problem, or simply age. But simply making sure the key switch is firmly to the run position seems to solve it.

Sounds like it. Thanks for the reply. I'm thinking it was something like that also. Something freaky. I do think I'm having some trouble somewhere in the charging system. Thanks, :) Mickey

You say your yellow wires are putting out 5 volts? How are you measuring this?

With a digital volt meter, It went up over 6 close to 7 when I started turning on all my lights. voltage gauge on the bike dropped so I checked the battery and it was down to 12.06v. Went for a ride and it stayed at 12.06 turned on just the fog lights and the dash and head lights dimmed so low I couldn't see them. I do have a lot of lights but I used to ride with them on at night once and awhile and didn't have this much trouble. they would drain a little bit but no problems like this. I would turn them off a few blocks from the house and it went back up.

OK, first off, the yellow wires are coming from the stator, which puts out AC voltage. I suspect you may be trying to measure DC on these yellow wires, which will mean you aren't reading the correct voltage. At around 3500 RPM, you should be seeing at least 48 VAC on each pair of yellow wires (1 to 2, 2 to 3 and 3 to 1).

If your bike is having trouble maintaining bus voltage, it could be any one of several things:

- Failing battery
- Failing stator
- Failing or incorrectly operating regulator
- Wire or connector corroded or providing resistance

The first thing to do is to measure the output of the stator's yellow wires, as I described above. Be careful when doing this, you are dealing with potentially lethal voltages, so don't go touching these wires with your bare hands when measuring these voltages. Treat them with the same respect you would treat the electrical wiring in your home.
