Motorcycle Questions? Ask a Mechanic.
Hi and thank you for your question.
If your solenoid is just clicking, it could be a few things. First, I would suggest checking all of the battery cable connections, starting at the battery, then at the solenoid, then at the starter motor for both the positive and negative. If all of them were tight, then I suggest removing all the spark plugs, putting them back in the caps then grounding the spark plugs on the cylinder head away from the open spark plug holes. Attempt to crank the starter now and see what happens. If it still doesn't want to crank, or sounds exceptionally slow, check the battery voltage. Do a static test of voltage on the battery and then a dynamic test where you leave the volt meter connected to the battery and crank the engine. This is called a voltage drop test. Observe the voltage while the engine is cranking. This tells you the condition of the battery. If the voltage is ok, like 12.5 volts or more statically, but drops severely when cranking, your battery needs to be replaced.
Let me know what you find.
Thank you for the additional information.
Please don't assume that is the extent of my diagnositics. I still need to know the results so we can move forward from here.
Now that you mention it, what exactly did you rebuild and has it run since the rebuild? It sounds like I need a lot more information relative to the recent rebuild, it could hold a clue to resolving this issue. Please be as detailed as possible, and include any other pertinent information as well.Thanks,
I have thought about this some more, and have another question. Did the engine stop turning over, then you put the battery charger with the engine start mode on the battery? Also, is the battery itself any good? Here is where I am going with this. If the battery is in good condition and the cables are tight, we have a mechanical problem with either the starter system or the the engine. A cold engine has less compression than a hot engine so if a good battery isn't spinning the engine over by itself, there is a mechanical issue. Unless you have a high compression head on it...... I still need to know if it will spin over with the spark plugs out, and what the voltage drop test results are.
Thank you for the additional information. Did the ski sit unused for an extended period of time waiting for the starter idler to be replaced? It sounds like you had a reason to believe the engine was cranking over slowly, so you added the booster. If it didn't change the cranking speed with the booster, it sounds like there are other mechanical issues with the engine or pump.
What impression are you talking about?
Are you able to do a voltage drop test on it?
I am still interested in the answers to the questions I posed in my first response.
I am interested in the current compression too.
