Hi, John the turn signal module is located on top of the frame in between the gas tanks for this scenario you will need your service/owners manual if you can not find the first and best tool you ever bought for your Harley, despair not, for a mere zero $0 you can download another one.

My 2011 fat boy lo has its flashers on. starts fine. is there a flasher button i may have turned on by mistake

If you press and hold both the right and left turn signal buttons at the same time, it turns on the four way flashers. Do the same thing to turn them off. It may not be your four way flashers though. Do you have a security system on your bike? Could be that. Hope this helps.

Good Luck

Have changed indicator units to smaller ones with bulbs 12v 10w and they dont flash and we cannot locate flasher unit to change - how do we fix problem without putting old indicators back on

By changing the bulbs, you have changed the load resistance on the flasher unit. You Fat Boy does not use a flasher like a car does. It has an electronic turn signal canceller on it, a "black box". To solve your problems, you need a "load equalizer" installed in the wiring harness of your bike. There are several types of units on the market. Badlands makes a good one.

Ride Safe.

Where is the flasher unit on a 1995 fat boy

Your Fat Boy does not have a conventional flasher unit like on the older cars and bikes. It has a turn signal cancelling unit on it that is a flat looking box about 1/2"thick by about 1" wide and about three inches long. On the Fat Boy, I THINK it's located on the frame between the tanks. It has one large plug on it with a lot of wires going into it.

What is the unit doing or not doing. These units are pretty dependable and usually don't give any trouble. But, they are expensive and you don't want to buy one unless you need one. I have a trouble shooting guide that I'll send you. It's far too much typing to type in here, four full pages with pictures. Contact me directly at and I'll send it to you.

Good Luck
