Default 1992 softail custom

Hey everybody, I'm stumped. I've got a 92 softail custom and I was riding it the other day. All of a sudden I get a boiling battery and high idle so I shut it down and I womt start back up. I've already installed a new v-REG. I changed all circuit breakers. My start button on my handle bars is intermediate on when it wants to turn the bike over. Also, I have no fire to coil. I've tried tracing wires and I am absolutely stumped. Any input is much appreciated

Welcome from North Beach, FL., USA!

Just in case you have not done this and I recommend this only as a suggestion....

Add a Signature Line in your USER set up for your bike year, model, and all the letters that Harley recognizes it with. Others will see it at the bottom which enables them to know your exact model if you ever ask a question. All Harleys are not the same and year and all the model letters make a big difference.

Also, add an Avatar of your favorite shot in the USER setup for the small picture others will see in the top left corner of your post.

It's also very helpful to read the 'HDF Site Rules' listed at the top of the new member area.


​​You're all set.... Enjoy the ride! ______________

Have you done any work recently that was on or near electrical components....?

If not, start at the beginning....

With the limited info you provide, you need to be systematic and thorough in your diagnosis to find the issues(s)... it all boils down to spark, fuel, and compression.

You had high idle and boiling battery.... That suggests an electrical issues and a possible fuel issue...

Boiling battery is obviously electrical... You replaced the VR but did you check the battery and the stator...?? Those three work together and one going bad can affect the other two... you need to figure out if your 12 volt system is healthy...

After addressing your 12v system, you need to decide if the power issues caused the high idle and lack of starting, or is that a fuel issue... If it is a fuel issue, then you need to go through your fuel system to find out why it raced the engine (carb problem, like stuck float) and now won't let it run...


Keep us informed as you go through your checks and many here will share their experiences and offer suggestions...

Over voltage could cause high idle and a battery to boil over.
If your voltage regulator isn’t properly grounded it can’t dump the extra voltage

Replace the battery, get it started with the regulator disconnected from the stator and do the charging system diagnostic.
You might need to get creative with a battery charger and fan to keep it running long enough to do a proper test.

I forgot to mention I did replace the battery, I've got 13.2 volts there. So, I infact know that that is okay. so that knocks out 1 more issue. My ground is good and secure. I however haven't checked my stator. That's something I'm unsure of how to do a diagnostic test on

Go to the Evo section on this site and there will be a thread stuck at the top that will run you through how to check your charging system. You'll find lots of tech info for your bike in the Evo section. good luck.

I was referring to the ground AT the Voltage Regulator, it needs to be grounded to work properly.
