Topic: Slow crank.

After market start button, fresh battery.

Slow crank with the button. Fast as hell when i jump solenoid.

Button or solenoid?

[calj737]

Wiring to button

[Sdsbassist]

Wire size? Not wired properly?

[hsas.69]

Why did you replace the button to begin with? The button shouldn't really affect the cranking speed too much cause its just the control to the solenoid which is a relay. The main power to the starter never goes through the switch, just fromvthw battery through the solenoid and to the starter.

[Sdsbassist]

Came that way. Handlebar button missing. Looks like button is wired to each post of sol.

[Sdsbassist]

Here's what i got. Button has 2 wires. Right now has one wire on each solenoid post.

[Sdsbassist]

Works better when i hook the wire that was on the Batt post directly to batt and pushed button

[Badluckhonda]

Best way way to wires solenoid from my experience is by giving constant power to it. The button provides the ground when pushed down and completes the circuit. If you wired it thee other way it'd probably burn the wire from the high amperage

[Sdsbassist]

So what post should i be on? Post with starter wire through button then ground?

When i hook up wires this way, nothin when i push

[Badluckhonda]

Don't really understand what you mean but if your switch has two wires do this. Make sure your selenoid getting 12volts as soon as you turn on the key. it should have two wires beside the lager wires that go to battery and starter. Wire one of these with 12volts after the ignition switch.

 So then on your switch/ starter button, run a good ground to one wires then the other wire to the ground on the solenoid. So now when you push the button it will ground out the selenoid

[Sdsbassist]

Where do i hook up the ground on the solenoid?

[Bodi]

This problem is inside the solenoid, not with the button or its wiring. Since crossing the studs gives good cranking, clearly the solenoid's internal high current contacts are not closing properly: the poor connection will be producing a lot of heat whenever you use it this way.
Remove the solenoid, disassemble the stud end, file clean flat contact surfaces on the stud contacts and switching bar. Clean the moving parts as well as you can. Reassemble and it should be OK. Replace it if it's badly burnt or seized mechanically.

[Sdsbassist]

I can do that. Question still remains...which post should i ground?

[Badluckhonda]

What color are the tw smaller wires on the selenoid ? If it oem the green one. Which is ground on these old honda

[Sdsbassist]

So hook it up to that?

[Sdsbassist]

And the other to the starter post?

[Badluckhonda]

Ok one more time. There's two large wires one the solenoid  one to battery positive thee other to the starter.

Which leaves the two smaller wires on the solenoid. One gets power after the ignition switch. And thee other goes to the starter button, which ground out the solenoid complets circuit

That's the way it was probably already hooked up. You just need clean up the solenoid

[Sdsbassist]

Gotcha. So find where the green wire ended up after the PO hack job and hook it to the button, then to a ground

[Don R]

If it's a factory start button it makes the ground when you push it.

[Don R]

 it's a custom job but i've used this,

Heres what i found today. Yellow/red and green/red. If i look correctly at the diagram, yellow red should be power all time, green red ground (through switch). My yellow/red was capped in the harness. Green red looks to be plugged into a ground connector.

Should i wire yellow red to a power after ignition, then green red to my switch and frame?

[Sdsbassist]

Check that, opposite. Yellow/red to button, green red to power.

[calj737]

Yellow/Red comes form the START button and delivers 12v to the solenoid. The Green/Red comes from the factory NEUTRAL switch (providing the ground when in Neutral). The 2 large studs are wired to the battery POS and the other to the starter motor.

Easy.

Im pretty sure this goes against what everyone else is saying.

Here's what i tried tonight. Hooked green red to direct power and used button for a ground, nothing. Green red to power and yellow red to frame...nothing. green red plugged into harness, yellow red to ground thru button nothing. 12v through button to yellow red. Nothing.
