turn signal flashs real fast with brake on

Postby tprender » Thu Sep 15, 2016 3:35 pm



I have a '95 that I got last summer. A couple of times people have stopped me saying that my turn signals are not working correct. I have checked and they both work good right and left, but when I put the brake on they will flash real fast. Is there some kind of add-on that will cause this to happen. Not sure if I should look for a problem or just leave it alone.

Sounds like a bad ground causing the turn signals to feed back through the brake light bulb. Check the ground points in the rear of the bike and check all the connectors in the rear. put some dielectric grease in any connectors you unplug. Try cleaning the turn signal switch contacts.

Those who say it cannot be done should try not to interrupt those who are doing it.

I had the same problem last year. It is a bad ground somewhere. I checked all of the ground connections on the bike (and there is a bunch), checked all the light bulbs, checked sockets, checked and rechecked everything. I had the bike stripped down and still could not find it. Drove me nuts trying to find it. I finally just ran a new ground from the brake/tail light to a ground under the seat. Fixed everything....

Thanks for the help, is there a list or do I just have to look around to find all of the grounds on the 1500. It sounds like the best is to just add a ground wire to the brake light or could the bad ground cause other problems that I don't know about?

If your turn signal lights start to glow when the brakes are applied, if your turn signals flash rapidly when you use them then chances are it is just a bad ground somewhere. I just added a ground wire and all has worked just fine for the last year and 9,000 miles. Nothing else seems to be affected.

Oh, and there are many ground locations plus many, many connectors that have ground wire connections in them. If you search ground connections here you can probably get a list of all the locations. I used to know them all but i have since forgotten where they all are unless I think on it really hard and I don't want to do that right now.

I would try wiring another ground say from the ground connection right under the seat on the frame to one of the sockets and see if that solves all of your problems.
