voltage regulator?

I had the same problem on my 90 fltcu. The connector from the stator was not making a good connection. It was intermittent which made it a bitch to find. Recheck the plug mine the radio would cut out and the blinkers stopped working when the plug was not connected. Don't go by the volt meter on the bike it can be off by a volt or two. Hope this helps.

The volt meter in the faring is accurate, but it only measures the voltage on the accessory line inside the faring, not battery voltage, which is what you would want. Keeping that in mind, it is still useful as a relative indicator of what is happening in the electrical system. When your volt meter reads 10V and your blinkers are not working, it is most likely because something is shorting to ground, causing a large current draw, which then is visible as a lower voltage inside the fairing.
Finding the intermittent short is a biatch. I have found a few over the years, but never when I was looking for it. A common problem with our bikes (per the forum here) seems to be wires rubbing the insulation off under the tank and at the steering neck. You might very closely inspect those areas for a start.

Hey guys, haven't found the prob yet, but updating anyway. Took the fuse panel out and cleaned it good, couldn't find any bare wires anywhere. Figured I'd run the bike over to him (10 mi) and buy a cycle electric v-reg from him just to see. The dash was at 13v there and back.
He said I'm charging fine, and to check the relays under the outer fairing. (He had the same problem, and it was corroded relays)
So I just pulled the fairing, is it ok to spray electric
Cleaner on the connectors, wires, fuse box?? It says it's ok on the can, but wanted to dbl check with the experts on here. Thanks

You will need to disconnect all wires before spraying.

If it's CRC electrical cleaner don't hose down the connectors that have a weather pack seal. A rubber seal around the housing of it that seals when connector is pushed together. Have had the stuff swell up this seal and not let the connector go back together as it should, makes for a bad connection.

I'm chasing the same issue. I have the same symptoms and I'll add a couple of others. Like the OP, my problem is intermittent so it is difficult to track down. When I am at 14 amps (normal) my blinkers cause the volt meter to bounce violently, from the normal 14 down to 8. The needle bounces with the flash of the blinker. This is not an intermittent symptom, this happens every time I put either blinker on.
When I am at the reduced voltage and the blinker won't come on, I can get it to come on by turning the headlight off. I can then turn the light back on and the blinker will stay on.
Sometimes, not always, when I put the blinker on it will go off when I hit the brake.
I'm thinking my problem is the voltage regulator. I didn't find any corroded wires.

Batteries fail but can be easily tested to determine failure.
Wiring needs special attension and determining good connections is your responsibility.
Follow your manuals instructions and do the deeds needed.

Morning guys! Picked up a new volt reg last night (96 ultra) did not realize it doesn't have a ground like the stock one did, is it built in? The new one is a cycle electric, ce-320 rectifying regulator. Says it's for 89 to 96 all flh, flt, cept fuel injected, which mine is carbed. Its a 32 amp also, thanks
