Hi All,

Went to the boat today and found the engine wouldn't start. Ignition panel switch and lights look good and the batteries are fully charged but engine makes rapid stream of clicks and won't turn over.

I cleaned all the battery terminals and connections but no success. Could it be the buss (I didn't clean it) or do you have any suggestions? Never had any problems before.

Thanks, Dick
 
if your batteries are charged and you cleaned and tightened the cable terminals I would check the terminals connections at the engine especially the ground. If that dosent do it than I would be thinking about the starter solenoid.
 
Dick-


Sounds like you're getting power to the relay, but not to the starter itself, or the starter is seized.

Start first with Chuck's suggestions above.

Then I'd next y connect a voltmeter negative lead to the ground and use the other (positive) lead to

1. See if the large cable bringing power into the starter solenoid is live with the full battery voltage, then

2. connect it to the output side of the relay and see if when the starter is activated and the klicking starts, the full voltage is being delivered to the cable or directly to the starter if that's how it's designed (solenoid on starter body, wired internally).

I'd also find out if I could spin the starter motor manually with a tool to see if the armature is seized.

If the motor is seized, you need a new one or a rebuild by a competent electrical technician.

If the motor is not seized, then maybe the solenoid is bad, especially if you can determine in #2 above that the full voltage is not being applied to the motor when the key is turned.

If you can't make a determination, the motor and solenoid can be detached and taken to a competent person or shop.

You could also "jump" the starter solenoid by supplying power directly to the motor from the supply (inlet) side of the solenoid and/or battery with a heavy cable (00 or better) to see if the motor itself spins and is is good, which would also help you find out where the open circuit occurs. I don't think this would back up voltage and current into anywhere it would do any damage, but I'm not familiar with your particular motor.

Be care when doing all of this, the size of the current involved can produce a lot of heat and start a fire, and the motor and it's Bendix drive gears can remove fingers easily.

Sometimes difficult repairs are best left to a professional repairman.

Always use caution, and when in grave doubt, don't!

Another possibility which Joe came close to touching on: Some times a damaged Bendix gear will cause similar symptoms. Take the cover off the motor and have someone hit the starter briefly, and observe if there is any movement of the starter motor or Bendix gear.
 
Thanks for all the suggestions. I'll let you know what I find. Likely won't be able to get to it until next Saturday due to work.
 
Sometimes batteries can show full voltage at rest(12.6) but if they have internal shorts/problems the voltage will drop drastically very quickly. It may even return to 12.6 after the load is removed. I would start with Brents suggestion and put a load test on the battery if you have a tester.

Put a voltmeter on the battery and watch it as you try the key. If the voltage drops drastically and quickly it would probably be one of 3 things. A bad battery, a bad connection or something seized and or shorted.

Mt guess would be the solenoid. If it is stuck, they can engage with a tap as Bob suggests. Extreme cold can also cause them to stick. Age can also weaken them to the point that they can no longer push the bendix into engagement.

Starters can seize up but seldom when they are being used regularly. If it was seized the bendix would probably still engage and this would cause a short. Sometimes with a bad solenoid the starter will spin without the drive engaged. Does it sound like the starter is spinning?

Regards, Rob
