Finishing the Installation

If you have not installed a new starter, inspect the starter's terminal-post to be sure it is free of corrosion and dirt; clean as needed.

To connect the new cable to the starter do the following:

  • Be sure only one nut is on the starter's terminal-post.
  • If you're installing a Warrior starter, check the post. It should have a rubber O-ring, and two brown plastic (dielectric) washers at its base. The washers should place the lower nut high enough so it won't touch the starter case.
  • If you're installing a stock starter, check the post. It should have two brown plastic (dielectric) washers at its base. The washers should place the lower nut high enough so it won't touch the starter case.
  • Snug the lower nut down against the washer(s) at the base of the post. If you skip this, the post may come loose.
  • Slip the rubber boot onto the cable.
  • Put the cable end on to the post.
  • Install and tighten the upper nut, while holding the lower nut using an open-end wrench. Do not use thread-lock, as you want to ensure a good electrical connection. Instead, just be sure you've got the nuts good and tight (but not excessive).
  • Apply some dielectric grease to the post and nuts to inhibit corrosion. Note: Do not use excessive grease, as it can seep into the cable and discolor the look, if you are installing transparent coated cables.
  • Pull the boot down over the post and nuts.

 

See the completed installation in the photo below.

If you removed the battery, reinstall it now.

After inspecting for corrosion, reconnect the positive (left side) battery cable. Remember to smear on some dielectric grease.

Then connect the negative (right-side) lead. Remember to smear on some dielectric grease.

Now turn on the ignition and hit the starter button. The starter should be noticeably more powerful--especially if you installed the Warrior starter.

If the starter won't engage at all, be sure your transmission is in neutral.

If it doesn't spin the engine with more authority, check your connections for a loose bolt or nut. Also try removing the bolts/nuts, cleaning the terminals and fasteners again, and then re-tightening them.

If, after thoroughly searching for a poor connection, you still have little, or no, starting power, you can suspect the starter or the battery. To test them, do the following:

  • Turn on the ignition.
  • If the lights don't shine brightly, the battery terminals may not have good connection.
  • Turn off the ignition.
  • Detach the new cable from the starter, and temporarily bolt one end of the stock cable to the starter post. (Be sure the stock cable ends are clean).
  • Be sure your transmission is in neutral.
  • While protecting yourself from electrical shock with thick rubber gloves or other insulation, touch the other end of the stock cable to the positive (left) side of the battery.
  • The starter should immediately spin.
  • If not, and yet the lights come on with the ignition, the starter may be bad.

You can also try this test again, using your stock starter--reinstalled.

Once everything checks out, just put the left side-cover back on and smile. You’ve done something very good for your bike.


Ride on.

I was having an issue with my starter where it would turn over once, wait a few seconds then turn over again and start the engine. I figured I would need to replace the starter. I started with the wires first since it was cheaper.  
Like night and day now, it rarely does the hesitation start any more.  
Great mod.  
One thing I had a problem with was the Warrior relay. I didn't know it was reverse wired to the batt.

great piece. I'm experiencing starter problem where it won't start but wires and motor get hot. What about the various relays. Don't they play a part??
THANK YOU

I just finished the cable install on my '00 R/S. I stayed w/the stock starter,but put a kit[(new brushes)$60] in it while I had it on the bench. Don't know if it's the cables or the fresh starter or (probably) the combination of the two,but the starter almost spins the motor out of the frame when I bump the button now. Time & money well spent.
Great, Great article

Randy, 
This is just an outstanding article. This install is not rocket science but it sure does give a novice like me a lot of confidence to tackle something they want to fix. The details were super. Thanks for your time.

If not, what is the length? 
Thanks.
