    We have been experiencing a starting problem since the middle of the summer. Pushing the start button we hear the new starter relay (changed out yesterday) engage with a good snap but the starter doesn’t engage with the fly wheel. The only sound when pressing the start button is the relay snap. Is my next step to remove cowling and do the go through the Skytek trouble shooting chart? Skytek starter was installed in 1997 with 1425 hours.

    Pat,

    Take a volt meter and set it to 12 – 20 volts. Then bridge the starter relay and have some one hit the starter (mags off, mixture lean) and you should only read about 0.5 to 1.0 volt. Then do the same for the starter cable (from the relay post to the starter post). Finally read the voltage at the starter.

    That should tell you all you need to know.

    You may need a new starter cable. Replace a lot of cables these days, most being 40 years old.

    Cheers

    If it’s the light weight Sky tec starter your starter mounted solenoid may be bad. Least ways it was in mine. Your has a good number of hours also. On mine the black plastic or Bakelite end was loose and the contacts weren’t contacting. Oh yeah it happened without any forewarning.

    Update on our starter issue.
    After cowl removal and depressing the start button, It took a “tap” on the selenoid to get the starter gear to engage the flywheel. Ordered and installed a new Skytek 149-12LS starter. Now when we depress the start button, the starter selenoid closes and the starter motor spins but it doesn’t extend and engage into the flywheel. We have cleaned every terminal from the battery, through the battery solenoid, through the starter selenoid and the starter cable to the starter. Used Corrosian X on all terminals and Checked proper torque on the battery terminals and tightness on every nut in sequence. Went through each step of the test procedure on Skytecks website for trouble shooting and we see 12 volts at the starter. Also there is 12 volts across the jumper wire on the starter selenoid. After all that we get the same result-starter motor turns but doesn’t kick out to engage the flywheel. There is no movement at all of the starter gear forward.
    Do we have a defective linkage in the selenoid? With a solid 12 volts at the starter, what else is required for the gears to engage? Any have any ideas? I plan to call the nice people at Skytec on Monday and go through this with them.

    It appears to be a defective solenoid. There is zero resistance through the coil of the “new” unit but testing the old one and other loaners on the field, I see about 1 ohm. Tim at Skytec is sending another one overnight. I can’t ask for more than that.
