Default So school me.

Ending the dreaded dead spot pause when you push the starter button. What am I missing with my 1993 FLSTC? Here's what I've done so far over time.

New battery
New stator and voltage regulator
Rebuilt the starter solenoid.
New starter relay
New starter
New start button and kill switch
Separated, cleaned, greased and reconnected every wiring harness plug I can lay hands on
Still have the problem nine starts out of ten. WTF?

Can you hear a click or just no sound at all?

Does this apply any https://www.hdforums.com/forum/evo/8...ded-click.html

Not the same issue.

The issue is when the start button is pressed, the starter cranks the engine until it hits compression and the starter motor stalls.

My `89 Softail has done this for 35 years.

It did it with the original lame starter, and still does it with an all ***** starter.

I have always attributed it to the starter gearing, 9 tooth pinion gear and 66 tooth ring gear.

The factory changed the ratio between the pinion and ring gear for the `94 model year.

I have been considering changing to the 10/84 setup.

10/84

The dreaded click. That's the term I was searching for. I think I'll try the heavier gauge wire thing first then maybe the second relay if necessary. Thanks.

Exactly! I considered that connection to a compression issue but didn't know any way around it. Thanks

I had been having a sort of "low grunt"...then kick in and start on my '85 FXRS. New battery didn't resolve it. On a hunch...I disconnected the wires at the common ground on the frame. Cleaned and wire brushed the spot on the frame, and each ring terminal. Starts right up now....no "grunts".
Quality of your ground connections is critical on these 12 volt systems.

The quality of the entire electrical path is critical, not just the ground side.

I have installed an additional mass to the frame, a thicker cable for the solenoid and I have replaced the breaker with modern fuses direct to the battery, I have no more dead click (new relay and rebuild the selonoid too) in my 91 flhs

If I don't kickstart my 85 FXWD first thing in the morning, I tap the starter button a few times to eliminate that. Fires right up.

This thread is not about the dreaded click, it is about starter stall.
