bike is having major electrical issues!?

So i just upgraded the front turn signals to flush mount led and also side mirror with built in led turn signals. Since then I'm blowing the turn signals fuse non stop and now losing my tachometer on and off. Not to mention after riding for over 30 min I turn the bike of and it has a dead start? If I jump it with another bike it will fire right up. Anyone know the issue and if you do a link to a Web site with detailed iinstructions on how to test the faulty areas before I go replacing the voltage regulator and the stator?

It's likely one of two things:

1) Faulty R/R (voltage regulator). It fails often on these bikes as they get older and had inferior technology to begin with. You can read Tweety's Mosfet R/R thread to learn how to upgrade this part. It is not likely the stator, so don't go down that road (yet).

2) Bad wiring of the turn signals. Did the issues happen immediately after this install? If so, I'd check your connections carefully on the signals and the wires leading to them. A shorted circuit could blow fuses or maybe even draw from the battery.

I have a feeling it's number 1. When the bike is running, check the voltage across the battery terminals (at idle and at higher rpm's). If it's too high or too low, then you know what the issue is. Too high of voltage will blow fuses and too low of voltage obviously doesn't charge the battery correctly. A faulty R/R can cause both.

The turn signals worked fine for about 2 weeks after install. Now all these issues are going on at once. At idea the bike sometimes hits hard like it lost all voltage for a split second and sometimes will still run other times will die

^ Yep, sounds like your R/R. Replace it pronto, before you get stranded or do damage by overcharging. Replace it with a MOSFET unit if at all possible, and it won't happen again.

My vote is R/R as well

8541Hawk will become famous soon enough
Do you have a multi-meter? If so it is easy to test the components before you replace anything.

While it is more than likely the R\R, I hate just throwing parts at a problem.

If you have a meter, what is the voltage of the battery with the engine off?
Then get the reading for idling and at around 3K RPM.

Then to check the stator take a resistance reading on the 3 legs.
Don't worry too much about the Ohm reading except to make sure all 3 read the same (or very close)

+1 Do it right and save yourself agreevation

What is this mosfet and do any of you have a link on where to buy it and is this solution just as easy as plug and play? Or I'd there modifying that needs to be done

Wait, hold on... that was the actual stock R/R taken off your bike? I seriously thought someone photoshopped that **** on there!

Depends on where you plug it.

Got me the first time too, mine didn't say that.

Dear Hairy,
Check MOSFET Regulator/Rectifiers - The Why & The How in the Knowledge Base. All the answers are there and do as 8541Hawk and NHSH suggest. Welcome aboard.

So i found the issue you where all.right it was the R/R I was out riding yesterday and my friend screams your *** end is smoking like crazy! Sure enough the R/R went up and took the wires and the harness with it...

It's not the first time we heard that here. Since you're posting this, I assume your *** did not light a fire?

Replace some wires, get a couple new connnectors (unless you hardwire it), a MOSFET R/R and you'll be ready to rock the Superhawk again. Unless the R/R took out other stuff with it (guages), which I really hope didn't happen.

Didn't we tell you? **** it is ;-), you could have saved yourself money and aggregation, but what's done is done, if the harness is beyond repair, just get a new one, I hope you didn't damage other components, these R/R's have a tendency to kill more than just the harness when they go this way, so check for the rest.

+1 to that

Mine killed my tach and after attempts to fix my tach(blown resistor) to no avail, further investigation has pointed to it killing the ICU...

Well now at least you don't have to test voltage to see if it's your r/r. And you got to leave an awesome contrail as a final farewell to the unit.
