QuikStart is always off? Is it worth spending $$$ to fix?

[D0T-C0M]

I have a 1995 130HP Johnson and after completing a timing check I noticed the QuikStart feature is never coming on. From the tests I've done it is determined that the power pack must be replaced as per the service manual. I am wondering if its worth changing the power pack to get this quik start feature to work. I do have to say that the engine spits and sputters a bit when the engine cold so I hope if I do spend the money it will at least fix this. What do you guys think? Should I spend the $$$ , why is this QuikStart feature important?

The Quickstart feature advances the ign timing a bit when the motor is cold, and then shuts off when the motor warms up. You have tested the Quickstart temp sensor?

Try advancing the throttle a bit (throttle only button, if equipped) when cold starting aim for about 1200RPM, when she starts cold. Now you will need to figure out manually when the motor is warm, figure 1 minute in summer, 3 minutes in winter.

Re: QuikStart is always off? Is it worth spending $$$ to fix?

Although I have tested and confirmed my temp sensor as being good, I have opened and grounded the white/black wire manually to do these test. The QuikStart should come on and stay on everytime the engine is below 1100RPM and while the engine sensor indicates the engine is "cold" and for 5 seconds every time the engine starts. QuikStart is disabled any time the RPM is over 1100. In my case the timing never moves off its base timing.

So if really this QuikStart feature is only a convenience feature then I might wait till I get a good deal on ebay etc.

Is your port temp sensor a black/white wire or the same tan one as starboard? The one with the black/white has a separating diode in it to do both the low temps on quickstart and the high temps on the warning buzzer. Does it have the right temp sensor in there? If I were you I wouldn't buy a new powerpack to get the quickstart working if indeed that ends up being what is wrong.

Re: QuikStart is always off? Is it worth spending $$$ to fix?

My port side temp sensor has 2 wires. One is a solid tan colored wire (overtemp) and it has a white wire with a black stripe used for QuikStart. My understanding after reading the service manual is the white/black wire going to the power pack is looking for a short to ground that indicates an engine running under normal operating temperature. I manualy grounded this wire to ground while doing my timing tests so the QuikStart feature should always be on while its grounded (under 1100RPM). Regardless of the temperature switch the QuikStart feature should always come on for 5 seconds after every engine start (under 1100 RPM) and this is not happening.

I wouldn't lose any sleep over it if I were you. I have two starboard temp sensors (no tan ) from a head swap and I get by just fine. It advances for the few seconds then drops down and I just let it warm up.

Re: QuikStart is always off? Is it worth spending $$$ to fix?

So what your saying your engine is "always" running in QuikStart mode (under 1100RPM) unless you grounded the wire going to the power pack?

If you run your mtr above 3000 rpm in the water and ground out a tan wire to the temp sender will the mtr go into Slow as it should?? And will the warning horn sound ??

@boobie what does that have to do with the QuikStart feature?

Re: QuikStart is always off? Is it worth spending $$$ to fix?

I do believe the power coil on the stator runs Both Quickstart AND Slow.

It's my understanding (someone correct me if I'm wrong) that without the correct sensor it simply doesn't know to stay in QS. Dead neutral, fire it up, RPMs run up for about 5 seconds or so, then they drop even though it's still cold. I think the qs comes on mandatorily for that time period then shuts off if it doesn't detect that it ought to still be on because the motor is cold, because it believes no signal=warm motor.

boobie are you saying no quick start lead, no slow activation?

As per the service manual for my motor(1995 130HP) which has a 2 wire port temp sensor. One wire is a tan color and the other is a white/black wire. The internals of the temp switch consist of 2 dry contacts, one from the tan wire to the metal casing of the sensor which closes on temperature higher than 203f and the other contact is between the white/black wire and sensor casing and closes at temperatures higher than 96f.

If you have the same type installation as I do than by disconnecting the white/black will simulate an always "open" condition and the power pack will always think the motor is in the "cold" state thus the QuikStart feature will always be on until the 1100RPM mark is attained.

Re: QuikStart is always off? Is it worth spending $$$ to fix?

The service manual describes QuikStart as follows,

QuikStart electronic starting, which automatically advances ignition timing when the engine temp. is less than 96f AND for approximately 5 seconds each time the engine is started, regardless of temperature. Once the QuikStart electronic starting has been canceled by the egine temp sensor, the engine must be turned off before the ignition advance cycle can be repeated.

QuikStart electronic starting also incorporates an RPM limit that cancels the ignition advance when the engine speed exceeds approximately 1100RPM.

does your manual describe the SLOW feature if your model has it?...

Re: QuikStart is always off? Is it worth spending $$$ to fix?

Yes it does,

S.L.O.W. warning system, which gradually limits engine speed to approximately 2500 RPM when engine temperature exceeds 203f on V4 models.

To resume normal operation after S.L.O.W. warning system has activated, turn the engine off and allow it to cool to 162f on V4 models.

The S.L.O.W. warning system depends on input from the port sensor or starboard temperature switch tan lead. The S.L.O.W. warning system is isolated from other warning horn signals by a blocking diode in the engine wiring harness.

Reading that manual info again you are right it is going to perpetually be in qs until it gets grounded or hits 1100.

I think what boobie was getting at is that if the same stator power coil is used to run both SLOW and QS, and your your QS isn't working, is your SLOW not working either, which might indicate a stator problem not a powerpack problem?

 

[D0T-C0M]

Re: QuikStart is always off? Is it worth spending $$$ to fix?

Well as per the service manual the stator is supposed to be 96ohms +/-10 ohms range between both orange and orange/black power coil side wires and each wire should show open (very high resistance) between each wire and engine ground. Everything tested out ok so the power coil is considered good and the power pack needs to be changed.

I do believe the power coil on the stator runs Both Quickstart AND Slow.

You are right both use the power coil. I never tested the SLOW function but out of curiousity I will next time I am on the water. It can't hurt to double check the power coil before condemning the power pack

Archcycle, You hit the nail on the head. That's what I was trying to get across to him.

 

[D0T-C0M]

Re: QuikStart is always off? Is it worth spending $$$ to fix?

@boobie thanks I do appreciate the help. I am going to try the slow feature just out of curiosity to see if the SLOW works or not. Although it will change nothing for the end result. If the slow works than great that just confirms that the power coil is good for sure and I still have to change the power pack to get the QuikStart to work. If the slow doesn't work than you do the same test on the power coil as with the QuikStart testing and the end result is the power pack needs to be changed.

DOT-COM. I'm one of those guys that just don't like to replace anything unless I know it's bad. There are to many parts changers in this world and that gets costly. Maybe that's one of the faults of coming from the old school. LOL.
